Freebuff

Full-featured AI coding agent, completely free with no subscription

Quick answer

Freebuff — Full-featured AI coding agent, completely free with no subscription. It's free. Best for building side projects and prototypes without paying for a coding agent subscription.

Freebuff is a fully free, ad-supported AI coding agent that gives developers access to Claude Code and Cursor-class capabilities across five distinct product surfaces without requiring a subscription, API key, or credit card. Built by the team behind Codebuff, a Y Combinator F24-backed company, Freebuff is designed for developers who want powerful AI-assisted coding without the financial commitment of monthly paid plans from competitors like Cursor or Lovable. The platform spans a CLI tool, a desktop application, a web app builder, a cloud sandbox, and a chat interface, making it one of the most versatile free coding agents available today. Developers working solo on side projects, students learning to code, and professionals who want to experiment with AI coding before committing to a paid tool will find Freebuff especially appealing. The ad-supported model keeps costs at zero for end users while the established team behind it lends credibility to its long-term development, though users should be aware that throttling is possible under the free tier and long-term sustainability depends on the ad revenue model holding up over time.

Key features
