# Merge request widgets **(FREE)**
The **Overview** page of a merge request displays status updates from services
that perform actions on your merge request. All subscription levels display a
widgets area, but the content of the area depends on your subscription level
and the services you configure for your project.
## Pipeline information
If you've set up [GitLab CI/CD](../../../ci/index.md) in your project,
a [merge request](index.md) displays pipeline information in the widgets area
of the **Overview** tab:
- Both pre-merge and post-merge pipelines, and the environment information, if any.
- Which deployments are in progress.
If an application is successfully deployed to an
[environment](../../../ci/environments/index.md), the deployed environment and the link to the
[review app](https://about.gitlab.com/stages-devops-lifecycle/review-apps/) are both shown.
NOTE:
When the pipeline fails in a merge request but it can still be merged,
the **Merge** button is colored red.
## Post-merge pipeline status
When a merge request is merged, you can see the post-merge pipeline status of
the branch the merge request was merged into. For example, when a merge request
is merged into the [default branch](../repository/branches/default.md) and then triggers a deployment to the staging
environment.
Ongoing deployments are shown, and the state (deploying or deployed)
for environments. If it's the first time the branch is deployed, the link
returns a `404` error until done. During the deployment, the stop button is
disabled. If the pipeline fails to deploy, the deployment information is hidden.
For more information, [read about pipelines](../../../ci/pipelines/index.md).
## Merge when pipeline succeeds (MWPS)
Set a merge request that looks ready to merge to
[merge automatically when CI pipeline succeeds](merge_when_pipeline_succeeds.md).
## Live preview with Review Apps
If you configured [Review Apps](https://about.gitlab.com/stages-devops-lifecycle/review-apps/) for your project,
you can preview the changes submitted to a feature branch through a merge request
on a per-branch basis. You don't need to check out the branch, install, and preview locally.
All your changes are available to preview by anyone with the Review Apps link.
With GitLab [Route Maps](../../../ci/review_apps/index.md#route-maps) set, the
merge request widget takes you directly to the pages changed, making it easier and
faster to preview proposed modifications.
[Read more about Review Apps](../../../ci/review_apps/index.md).
## License compliance **(ULTIMATE)**
If you have configured [License Compliance](../../compliance/license_compliance/index.md) for your project, then you can view a list of licenses that are detected for your project's dependencies.
## External status checks **(ULTIMATE)**
If you have configured [external status checks](status_checks.md) you can
see the status of these checks in merge requests
[in a specific widget](status_checks.md#status-checks-widget).
