Freebuff Review

Depends

Should I use Freebuff?

Free coding agent: CLI + Web for full-stack apps. No subscription, no setup, no lock-in. - freebuff.com

· 1 month ago

Buy it if you want a zero-cost coding agent for learning, side projects, or escaping $20-50/month subscriptions. Skip it for production or commercial work where code quality, security posture, and predictable limits matter.
