Frequently Asked Questions
5 questions
Codeium is significantly better for open-source work. It offers unlimited free completions (vs Supermaven's 50/month), is trained on permissively-licensed code avoiding GPL concerns, and supports more editors like Vim and Emacs commonly used in open-source communities. The unlimited free tier means contributors can use it indefinitely without hitting limits.
