Codebuff
Multi-agent coding platform with composable agents; open source, with a free ad-supported CLI.
About
Codebuff (previously Manicode) is a coding agent built around a composable multi-agent architecture. When you ask it to add authentication to your API, it can spin up a file-picker agent to learn your codebase, a planner to order the work, an editor to make precise changes, and a reviewer to validate them. The core repo is open source (TypeScript monorepo) and ships a JS/TS SDK plus a TUI client.
Its unusual move is Freebuff, a free coding agent funded by small text ads shown in the terminal instead of subscriptions. You get 100 Freebucks a day across models, with some models unmetered. The honest picture: ad-supported means you trade attention for access, the free-tier models are not the strongest coders, and the multi-agent orchestration adds latency versus single-model tools.
What it can do
- Composable multi-agent coding workflows
- File picker, planner, editor, and reviewer subagents
- Free ad-supported tier with daily Freebucks
- JS/TS SDK for building custom agents
- Privacy-first: codebase not stored or used for training
Setup
Install with npm and run freebuff in your project directory, or clone the open-source repo at CodebuffAI/codebuff for the full platform and SDK.
Prerequisites
Node.js and a terminal. No API key or credit card needed for the free tier.
