Refact.ai is an open-source, local-first AI coding assistant and autonomous software-engineering agent built by Small Magellanic Cloud Ai Ltd. ("SmallCloud"). The product combines an IDE-integrated chat experience (Ask / Explore / Debug / Review / Plan modes), accurate code completion powered by Qwen2.5-Coder with RAG over the workspace, and the Refact Agent — an autonomous mode that plans, executes, and iterates on engineering tasks end-to-end, integrating with Git hosts, databases, shells, browsers, and MCP servers. The full agent stack — a Rust HTTP/LSP engine (`refact-lsp`), a React/Vite chat GUI, and VS Code + JetBrains plugins — is open source under BSD-3-Clause at github.com/smallcloudai/refact and ranked #1 open-source agent on SWE-bench Lite (60.0%) and 93.3% on Aider's Polyglot benchmark with thinking mode. Refact supports a cloud SaaS tier (Free / Pro / Enterprise) — though Refact Cloud is being wound down in favor of BYOK + self-hosting — plus enterprise on-premise deployment with LLM fine-tuning, AWS Marketplace listings, and bring-your-own-key access to Anthropic, OpenAI, Google, xAI, DeepSeek, Groq, Ollama, LM Studio, vLLM, GitHub Copilot, and any OpenAI-compatible endpoint. Refact is positioned as a privacy-preserving, self-hostable alternative to closed cloud coding agents — workspace context, checkpoints, knowledge graphs, and trajectories are stored locally; no code is sent to the vendor's servers in self-hosted mode.
