Before you commit
Verify the exact license and confirm no paid upsells or usage caps in the repo before adopting. Check if the agent runs fully locally or requires external APIs that could incur costs. Test self-hosting requirements and community support levels, as maintenance falls on you. Compare feature depth against your task complexity since free tools often lack enterprise polish or SLAs.

Can I use them commercially?
