Why people consider alternatives to LGTM
LGTM.com was a code analysis platform that utilized CodeQL technology to automatically detect potential security issues and code quality problems in repositories.
Teams most often switch away when one of these starts to bite:
- A feature or quota ceiling that a paid specialist covers and this free tool does not.
- Missing integrations with the rest of your stack.
- Performance or scale limits as your needs grow.
- A specific feature gap you have hit in testing & qa.
The 8 alternatives below cover the same core job (testing & QA) with different trade-offs.
