What is LGTM?

Editorial review

LGTM.com was a code analysis platform that utilized CodeQL technology to automatically detect potential security issues and code quality problems in repositories. It integrated with GitHub, providing analysis on new commits and pull requests, and displayed code quality badges. The platform also offered a query console for advanced users to write and run custom code analysis queries. Following its acquisition by GitHub, LGTM.com's core technology, CodeQL, was integrated directly into GitHub as 'GitHub code scanning'. As of December 2022, LGTM.com has been deprecated and shut down. Existing users were encouraged to migrate their repositories to GitHub code scanning, which offers equivalent and enhanced functionalities for continuous code security analysis.
