GitLab application limits (FREE SELF)

GitLab, like most large applications, enforces limits within certain features to maintain a minimum quality of performance. Allowing some features to be limitless could affect security, performance, data, or could even exhaust the allocated resources for the application.

Rate limits

Rate limits can be used to improve the security and durability of GitLab.

Read more about configuring rate limits.

Issue creation

Introduced in GitLab 12.10.

This setting limits the request rate to the issue creation endpoint.

Read more about issue creation rate limits.

  • Default rate limit: Disabled by default.

  • GitLab.com: Free members may invite 20 members per day.
  • Self-managed: Invites are not limited.

Webhook rate limit

Limit the number of times any given webhook can be called per minute. This only applies to project and group webhooks.

Calls over the rate limit are logged into auth.log.

To set this limit for a self-managed installation, run the following in the GitLab Rails console:

# If limits don't exist for the default plan, you can create one with:
# Plan.default.create_limits!

Plan.default.actual_limits.update!(web_hook_calls: 10)

Set the limit to 0 to disable it.

  • Default rate limit: Disabled (unlimited).

Gitaly concurrency limit

Clone traffic can put a large strain on your Gitaly service. To prevent such workloads from overwhelming your Gitaly server, you can set concurrency limits in Gitaly's configuration file.

Read more about Gitaly concurrency limits.

  • Default rate limit: Disabled.

Number of comments per issue, merge request, or commit

Introduced in GitLab 12.4.

There's a limit to the number of comments that can be submitted on an issue, merge request, or commit. When the limit is reached, system notes can still be added so that the history of events is not lost, but the user-submitted comment fails.

  • Max limit: 5,000 comments.

Size of comments and descriptions of issues, merge requests, and epics

Introduced in GitLab 12.2.

There is a limit to the size of comments and descriptions of issues, merge requests, and epics. Attempting to add a body of text larger than the limit, results in an error, and the item is also not created.

It's possible that this limit changes to a lower number in the future.

  • Max size: ~1 million characters / ~1 MB.

Size of commit titles and descriptions

Introduced in GitLab 13.9

Commits with arbitrarily large messages may be pushed to GitLab, but when displaying commits, titles (the first line of the commit message) limits to 1KiB, and descriptions (the rest of the message) limits to 1MiB.

Number of issues in the milestone overview

The maximum number of issues loaded on the milestone overview page is 500. When the number exceeds the limit the page displays an alert and links to a paginated issue list of all issues in the milestone.

  • Limit: 500 issues.

Number of pipelines per Git push

Introduced in GitLab 11.10.

The number of pipelines that can be created in a single push is 4. This limit prevents the accidental creation of pipelines when git push --all or git push --mirror is used.

This limit does not affect any of the updated merge request pipelines. All updated merge requests have a pipeline created when using pipelines for merge requests.

Retention of activity history

Activity history for projects and individuals' profiles was limited to one year until GitLab 11.4 when it was extended to two years, and in GitLab 12.4 to three years.

Number of embedded metrics

Introduced in GitLab 12.7.

There is a limit when embedding metrics in GitLab Flavored Markdown (GFM) for performance reasons.

  • Max limit: 100 embeds.

Number of webhooks

To set the maximum number of group or project webhooks for a self-managed installation, run the following in the GitLab Rails console:

# If limits don't exist for the default plan, you can create one with:
# Plan.default.create_limits!

# For project webhooks
Plan.default.actual_limits.update!(project_hooks: 200)

# For group webhooks
Plan.default.actual_limits.update!(group_hooks: 100)

Set the limit to 0 to disable it.

  • Default maximum number of webhooks: 100 per project, 50 per group
  • Maximum payload size: 25 MB

For GitLab.com, see the webhook limits for GitLab.com.

Pull Mirroring Interval

Introduced in GitLab 13.7.

The minimum wait time between pull refreshes defaults to 300 seconds (5 minutes). For example, a pull refresh only runs once in a given 300 second period, regardless of how many times you trigger it.

This setting applies in the context of pull refreshes invoked via the projects API, or when forcing an update by selecting the Update now ({retry}) button within Settings > Repository > Mirroring repositories. This setting has no effect on the automatic 30 minute interval schedule used by Sidekiq for pull mirroring.

To change this limit for a self-managed installation, run the following in the GitLab Rails console:

# If limits don't exist for the default plan, you can create one with:
# Plan.default.create_limits!

Plan.default.actual_limits.update!(pull_mirror_interval_seconds: 200)

Incoming emails from auto-responders

Introduced in GitLab 12.4.

GitLab ignores all incoming emails sent from auto-responders by looking for the X-Autoreply header. Such emails don't create comments on issues or merge requests.

Amount of data sent from Sentry through Error Tracking

Introduced in GitLab 12.6.

Sentry payloads sent to GitLab have a 1 MB maximum limit, both for security reasons and to limit memory consumption.

Max offset allowed by the REST API for offset-based pagination

Introduced in GitLab 13.0.

When using offset-based pagination in the REST API, there is a limit to the maximum requested offset into the set of results. This limit is only applied to endpoints that support keyset-based pagination. More information about pagination options can be found in the API docs section on pagination.

To set this limit for a self-managed installation, run the following in the GitLab Rails console:

# If limits don't exist for the default plan, you can create one with:
# Plan.default.create_limits!

Plan.default.actual_limits.update!(offset_pagination_limit: 10000)
  • Default offset pagination limit: 50000.

Set the limit to 0 to disable it.

CI/CD limits

Number of jobs in active pipelines

Introduced in GitLab 12.6.

The total number of jobs in active pipelines can be limited per project. This limit is checked each time a new pipeline is created. An active pipeline is any pipeline in one of the following states:

  • created
  • pending
  • running

If a new pipeline would cause the total number of jobs to exceed the limit, the pipeline fails with a job_activity_limit_exceeded error.

  • GitLab SaaS subscribers have different limits defined per plan, and they affect all projects under that plan.
  • On GitLab Premium self-managed or higher installations, this limit is defined under a default plan that affects all projects. This limit is disabled (0) by default.

To set this limit for a self-managed installation, run the following in the GitLab Rails console:

# If limits don't exist for the default plan, you can create one with:
# Plan.default.create_limits!

Plan.default.actual_limits.update!(ci_active_jobs: 500)

Set the limit to 0 to disable it.

Maximum number of deployment jobs in a pipeline

Introduced in GitLab 13.7.

You can limit the maximum number of deployment jobs in a pipeline. A deployment is any job with an environment specified. The number of deployments in a pipeline is checked at pipeline creation. Pipelines that have too many deployments fail with a deployments_limit_exceeded error.

The default limit is 500 for all GitLab self-managed and SaaS plans.

To change the limit for a self-managed installation, change the default plan's limit with the following GitLab Rails console command:

# If limits don't exist for the default plan, you can create one with:
# Plan.default.create_limits!

Plan.default.actual_limits.update!(ci_pipeline_deployments: 500)

Set the limit to 0 to disable it.

Number of CI/CD subscriptions to a project

Introduced in GitLab 12.9.

The total number of subscriptions can be limited per project. This limit is checked each time a new subscription is created.

If a new subscription would cause the total number of subscription to exceed the limit, the subscription is considered invalid.

  • GitLab SaaS subscribers have different limits defined per plan, and they affect all projects under that plan.
  • On GitLab Premium self-managed or higher installations, this limit is defined under a default plan that affects all projects. By default, there is a limit of 2 subscriptions.

To set this limit for a self-managed installation, run the following in the GitLab Rails console:

Plan.default.actual_limits.update!(ci_project_subscriptions: 500)

Set the limit to 0 to disable it.

Limit the number of pipeline triggers

Introduced in GitLab 14.6.

You can set a limit on the maximum number of pipeline triggers per project. This limit is checked every time a new trigger is created.

If a new trigger would cause the total number of pipeline triggers to exceed the limit, the trigger is considered invalid.

Set the limit to 0 to disable it. Defaults to 150 on self-managed instances.

To set this limit to 100 on a self-managed installation, run the following in the GitLab Rails console:

Plan.default.actual_limits.update!(pipeline_triggers: 100)

This limit is enabled on GitLab.com.

Number of pipeline schedules

Introduced in GitLab 12.10.

The total number of pipeline schedules can be limited per project. This limit is checked each time a new pipeline schedule is created. If a new pipeline schedule would cause the total number of pipeline schedules to exceed the limit, the pipeline schedule is not created.

GitLab SaaS subscribers have different limits defined per plan, and they affect all projects under that plan.

On GitLab Premium self-managed or higher installations, this limit is defined under a default plan that affects all projects. By default, there is a limit of 10 pipeline schedules.

To set this limit for a self-managed installation, run the following in the GitLab Rails console:

Plan.default.actual_limits.update!(ci_pipeline_schedules: 100)

Limit the number of pipelines created by a pipeline schedule per day

Introduced in GitLab 14.0.

You can limit the number of pipelines that pipeline schedules can trigger per day.

Schedules that try to run pipelines more frequently than the limit are slowed to a maximum frequency. The frequency is calculated by dividing 1440 (the number minutes in a day) by the limit value. For example, for a maximum frequency of:

  • Once per minute, the limit must be 1440.
  • Once per 10 minutes, the limit must be 144.
  • Once per 60 minutes, the limit must be 24

There is no limit for self-managed instances by default.

To set this limit to 1440 on a self-managed installation, run the following in the GitLab Rails console:

Plan.default.actual_limits.update!(ci_daily_pipeline_schedule_triggers: 1440)

This limit is enabled on GitLab.com.

Number of instance level variables

Introduced in GitLab 13.1.

The total number of instance level CI/CD variables is limited at the instance level. This limit is checked each time a new instance level variable is created. If a new variable would cause the total number of variables to exceed the limit, the new variable is created.

On self-managed instances this limit is defined for the default plan. By default, this limit is set to 25.

To update this limit to a new value on a self-managed installation, run the following in the GitLab Rails console:

Plan.default.actual_limits.update!(ci_instance_level_variables: 30)

Maximum file size per type of artifact

Introduced in GitLab 13.3.

Job artifacts defined with artifacts:reports that are uploaded by the runner are rejected if the file size exceeds the maximum file size limit. The limit is determined by comparing the project's maximum artifact size setting with the instance limit for the given artifact type, and choosing the smaller value.

Limits are set in megabytes, so the smallest possible value that can be defined is 1 MB.

Each type of artifact has a size limit that can be set. A default of 0 means there is no limit for that specific artifact type, and the project's maximum artifact size setting is used:

Artifact limit name Default value
ci_max_artifact_size_accessibility 0
ci_max_artifact_size_api_fuzzing 0
ci_max_artifact_size_archive 0
ci_max_artifact_size_browser_performance 0
ci_max_artifact_size_cluster_applications 0
ci_max_artifact_size_cluster_image_scanning 0
ci_max_artifact_size_cobertura 0
ci_max_artifact_size_codequality 0
ci_max_artifact_size_container_scanning 0
ci_max_artifact_size_coverage_fuzzing 0
ci_max_artifact_size_dast 0
ci_max_artifact_size_dependency_scanning 0
ci_max_artifact_size_dotenv 0
ci_max_artifact_size_junit 0
ci_max_artifact_size_license_management 0
ci_max_artifact_size_license_scanning 0
ci_max_artifact_size_load_performance 0
ci_max_artifact_size_lsif 100 MB (Introduced at 20 MB in GitLab 13.3 and raised to 100 MB in GitLab 13.6.)
ci_max_artifact_size_metadata 0
ci_max_artifact_size_metrics_referee 0
ci_max_artifact_size_metrics 0
ci_max_artifact_size_network_referee 0
ci_max_artifact_size_performance 0
ci_max_artifact_size_requirements 0
ci_max_artifact_size_sast 0
ci_max_artifact_size_secret_detection 0
ci_max_artifact_size_terraform 5 MB (introduced in GitLab 13.3)
ci_max_artifact_size_trace 0

For example, to set the ci_max_artifact_size_junit limit to 10 MB on a self-managed installation, run the following in the GitLab Rails console:

Plan.default.actual_limits.update!(ci_max_artifact_size_junit: 10)

Number of files per GitLab Pages web-site

The total number of file entries (including directories and symlinks) is limited to 100000 per GitLab Pages website.

This is the default limit for all GitLab self-managed and SaaS plans.

You can update the limit in your self-managed instance using the GitLab Rails console. For example, to change the limit to 100:

Plan.default.actual_limits.update!(pages_file_entries: 100)

Number of registered runners per scope

  • Introduced in GitLab 13.12. Disabled by default.
  • Enabled on GitLab.com in GitLab 14.3.
  • Enabled on self-managed in GitLab 14.4.
  • Feature flag ci_runner_limits removed in GitLab 14.4.
  • Feature flag ci_runner_limits_override removed in GitLab 14.6.

The total number of registered runners is limited at the group and project levels. Each time a new runner is registered, GitLab checks these limits against runners that have been active in the last 3 months. A runner's registration fails if it exceeds the limit for the scope determined by the runner registration token. If the limit value is set to zero, the limit is disabled.

  • GitLab SaaS subscribers have different limits defined per plan, affecting all projects using that plan.

  • Self-managed GitLab Premium and Ultimate limits are defined by a default plan that affects all projects:

    Runner scope Default value
    ci_registered_group_runners 1000
    ci_registered_project_runners 1000

    To update these limits, run the following in the GitLab Rails console:

    # Use ci_registered_group_runners or ci_registered_project_runners
    # depending on desired scope
    Plan.default.actual_limits.update!(ci_registered_project_runners: 100)
    

Maximum file size for job logs

The job log file size limit is 100 megabytes by default. Any job that exceeds this value is dropped.

You can change the limit in the GitLab Rails console. Update ci_jobs_trace_size_limit with the new value in megabytes:

Plan.default.actual_limits.update!(ci_jobs_trace_size_limit: 125)

Maximum number of active DAST profile schedules per project

Introduced in GitLab 14.3.

Limit the number of active DAST profile schedules per project. A DAST profile schedule can be active or inactive.

You can change the limit in the GitLab Rails console. Update dast_profile_schedules with the new value:

Plan.default.actual_limits.update!(dast_profile_schedules: 50)

Maximum size and depth of CI/CD configuration YAML files

The default maximum size of a CI/CD configuration YAML file is 1 megabyte and the default depth is 100.

You can change these limits in the GitLab Rails console:

  • To update the maximum YAML size, update max_yaml_size_bytes with the new value in megabytes:

    ApplicationSetting.update!(max_yaml_size_bytes: 2.megabytes)
    

    The max_yaml_size_bytes value is not directly tied to the size of the YAML file, but rather the memory allocated for the relevant objects.

  • To update the maximum YAML depth, update max_yaml_depth with the new value in megabytes:

    ApplicationSetting.update!(max_yaml_depth: 125)
    

To disable this limitation entirely, disable the feature flag in the console:

Feature.disable(:ci_yaml_limit_size)

Limit dotenv variables

Introduced in GitLab 14.5.

You can set a limit on the maximum number of variables inside of a dotenv artifact. This limit is checked every time a dotenv file is exported as an artifact.

Set the limit to 0 to disable it. Defaults to 0 on self-managed instances.

To set this limit to 100 on a self-managed instance, run the following command in the GitLab Rails console:

Plan.default.actual_limits.update!(dotenv_variables: 100)

This limit is enabled on GitLab.com.

Limit dotenv file size

Introduced in GitLab 14.5.

You can set a limit on the maximum size of a dotenv artifact. This limit is checked every time a dotenv file is exported as an artifact.

Set the limit to 0 to disable it. Defaults to 5KB.

To set this limit to 5KB on a self-managed installation, run the following in the GitLab Rails console:

Plan.default.actual_limits.update!(dotenv_size: 5.kilobytes)

Instance monitoring and metrics

Limit inbound incident management alerts

Introduced in GitLab 12.5.

You can limit the number of inbound alerts for incidents that can be created in a period of time. The inbound incident management alert limit can help prevent overloading your incident responders by reducing the number of alerts or duplicate issues.

To set inbound incident management alert limits:

  1. On the top bar, select Menu > Admin.
  2. On the left sidebar, select Settings > Network.
  3. Expand General Incident Management Limits.
  4. Select the Enable Incident Management inbound alert limit checkbox.
  5. Optional. Input a custom value for Maximum requests per project per rate limit period. Default is 3600.
  6. Optional. Input a custom value for Rate limit period. Default is 3600 seconds.

Prometheus Alert JSON payloads

Introduced in GitLab 12.6.

Prometheus alert payloads sent to the notify.json endpoint are limited to 1 MB in size.

Generic Alert JSON payloads

Introduced in GitLab 12.4.

Alert payloads sent to the notify.json endpoint are limited to 1 MB in size.

Metrics dashboard YAML files

Introduced in GitLab 13.2.

The memory occupied by a parsed metrics dashboard YAML file cannot exceed 1 MB.

The maximum depth of each YAML file is limited to 100. The maximum depth of a YAML file is the amount of nesting of its most nested key. Each hash and array on the path of the most nested key counts towards its depth. For example, the depth of the most nested key in the following YAML is 7:

dashboard: 'Test dashboard'
links:
- title: Link 1
  url: https://gitlab.com
panel_groups:
- group: Group A
  priority: 1
  panels:
  - title: "Super Chart A1"
    type: "area-chart"
    y_label: "y_label"
    weight: 1
    max_value: 1
    metrics:
    - id: metric_a1
      query_range: 'query'
      unit: unit
      label: Legend Label

Environment Dashboard limits (PREMIUM)

Introduced in GitLab 13.4.

See Environment Dashboard for the maximum number of displayed projects.

Environment data on deploy boards

Deploy boards load information from Kubernetes about Pods and Deployments. However, data over 10 MB for a certain environment read from Kubernetes aren't shown.

Merge requests

Diff limits

GitLab has limits around:

An upper and lower limit applies to each of these:

  • The number of changed files.
  • The number of changed lines.
  • The cumulative size of the changes displayed.

The lower limits result in additional diffs being collapsed. The higher limits prevent any more changes from rendering. For more information about these limits, read the development documentation.

Merge request reports size limit

Reports that go over the 20 MB limit aren't loaded. Affected reports:

Advanced Search limits

Maximum file size indexed

Introduced in GitLab 13.3.

You can set a limit on the content of repository files that are indexed in Elasticsearch. Any files larger than this limit only index the file name. The file content is neither indexed nor searchable.

Setting a limit helps reduce the memory usage of the indexing processes and the overall index size. This value defaults to 1024 KiB (1 MiB) as any text files larger than this likely aren't meant to be read by humans.

You must set a limit, as unlimited file sizes aren't supported. Setting this value to be greater than the amount of memory on GitLab Sidekiq nodes causes the GitLab Sidekiq nodes to run out of memory, as this amount of memory is pre-allocated during indexing.

Maximum field length

Introduced in GitLab 12.8.

You can set a limit on the content of text fields indexed for Advanced Search. Setting a maximum helps to reduce the load of the indexing processes. If any text field exceeds this limit, then the text is truncated to this number of characters. The rest of the text is not indexed, and not searchable. This applies to all indexed data except repository files that get indexed, which have a separate limit. For more information, read Maximum file size indexed.

  • On GitLab.com, the field length limit is 20,000 characters.
  • For self-managed installations, the field length is unlimited by default.

You can configure this limit for self-managed installations when you enable Elasticsearch. Set the limit to 0 to disable it.

Wiki limits

Snippets limits

See the documentation about Snippets settings.

Design Management limits

See the Design Management Limitations section.

Push Event Limits

Webhooks and Project Services

Introduced in GitLab 12.4.

Total number of changes (branches or tags) in a single push. If changes are more than the specified limit, hooks are not executed.

More information can be found in these docs:

Activities

Introduced in GitLab 12.4.

Total number of changes (branches or tags) in a single push to determine whether individual push events or a bulk push event are created.

More information can be found in the Push event activities limit and bulk push events documentation.

Package Registry Limits

File Size Limits

Introduced in GitLab 13.4.

The default maximum file size for a package that's uploaded to the GitLab Package Registry varies by format:

  • Conan: 3 GB
  • Generic: 5 GB
  • Helm: 5 MB
  • Maven: 3 GB
  • npm: 500 MB
  • NuGet: 500 MB
  • PyPI: 3 GB
  • Terraform: 1 GB

The maximum file sizes on GitLab.com might be different.

To set these limits for a self-managed installation, run the following in the GitLab Rails console:

# File size limit is stored in bytes

# For Conan Packages
Plan.default.actual_limits.update!(conan_max_file_size: 100.megabytes)

# For npm Packages
Plan.default.actual_limits.update!(npm_max_file_size: 100.megabytes)

# For NuGet Packages
Plan.default.actual_limits.update!(nuget_max_file_size: 100.megabytes)

# For Maven Packages

Plan.default.actual_limits.update!(debian_max_file_size: 100.megabytes)

# For Helm Charts
Plan.default.actual_limits.update!(helm_max_file_size: 100.megabytes)

# For Generic Packages
Plan.default.actual_limits.update!(generic_packages_max_file_size: 100.megabytes)

Set the limit to 0 to allow any file size.

Package versions returned

When asking for versions of a given NuGet package name, the GitLab Package Registry returns a maximum of 300 versions.

Dependency Proxy Limits

Introduced in GitLab 14.5.

The maximum file size for an image cached in the Dependency Proxy varies by file type:

  • Image blob: 5 GB
  • Image manifest: 10 MB

Branch retargeting on merge

Introduced in GitLab 13.9.

If a branch is merged while open merge requests still point to it, GitLab can retarget merge requests pointing to the now-merged branch. To learn more, read Branch retargeting on merge.
