Should I Use Freebuff?
Free coding agent: CLI + Web for full-stack apps. No subscription, no setup, no lock-in.
Depends
DependsBuy it if you want a zero-cost coding agent for learning, side projects, or escaping $20-50/month subscriptions.
Free ad-supported coding agent. Great for tinkering; capped by FreeCoins and uneven on some stacks. Not for critical work.
