GitHub Announces Planned Deprecation and Shutdown Schedule for LGTM.com

Following the integration of CodeQL analysis technology into GitHub code scanning, GitHub has announced a scheduled deprecation and shutdown plan for LGTM.com through the end of 2022.

According to GitHub's official announcement, LGTM.com's core features are now available within GitHub code scanning, prompting the gradual retirement of the platform. Users are advised to review official GitHub documentation and transition their workflows accordingly.

Scheduled Timeline and Key Milestones

• End of August 2022: New user sign-ups and the addition of new repositories will cease. Existing users can still log in, and current repositories will analyze new commits, though historical analysis will stop.
• October 2022: Migration assistance will be provided for active repositories, which includes automated pull requests adding GitHub Actions workflows for code scanning where feasible.
• End of November 2022: Analysis of new commits and pull requests on LGTM.com will officially stop.
• 16th of December 2022: LGTM.com will fully shut down, removing access to the service and the query console.

Practical Implications and Verification

Active users of LGTM.com must migrate their repositories and workflows to GitHub code scanning before the scheduled shutdown dates. Advanced configurations may require manual setup. Developers can verify announcements and read migration guides directly on the official GitHub Blog.
