The Stacked PRs CLI is free and open-source, that means you can use the CLI with no usage caps without creating an Aviator account. Simply follow the installation instructions to set up the CLI locally.
Aviator MergeQueue is a powerful merge-based automated workflow for pull requests in your GitHub repository and keeps your primary branch passing. Although completely optional, using the Aviator MergeQueue along with the stacked PRs CLI can significantly improve the developer experience for merging and updating the PRs.
To enable MergeQueue with Stacked PRs, create an Aviator account, configure MergeQueue mode, and set up the Aviator user access token in your Stacked PRs CLI config.
Chrome Extension is also a great way to visualize your stack from within GitHub pull request page.
