## What it is
Refact is an open-source, self-hosted AI coding agent written in Rust that plans and executes engineering tasks end-to-end from your IDE, with chat, code completion, RAG over your codebase, and tool integrations like GitHub and CI/CD. This original repository is now a legacy archive: active development has moved to a fork (JegernOUTT/refact) and Refact Cloud has been shut down.

## Use cases
- autonomous ai coding agent that fixes issues end-to-end
- self-hosted ai coding assistant for my codebase
- ai code completion in vscode and jetbrains
- chat with my repository using rag
- on-premise ai agent for enterprise development
- fine-tune a coding model on my own code
- open-source alternative to github copilot

## When to choose
- you want an open-source, self-hosted or on-prem AI coding agent with full data control
- you need IDE chat, completion, and autonomous agent workflows in one tool
- you want BYOK model choice, fine-tuning, and MCP/tool integrations

## When to avoid
- you expect the managed Refact Cloud service - it has been retired
- you want the actively developed version - use the JegernOUTT/refact fork instead
- you need a zero-setup hosted assistant without running your own engine
