Refact
Refact is a self-hosted AI coding assistant that lets you run models on your own infrastructure and fine-tune them on your codebase. Code never leaves your servers. MCP tools add controlled external access while keeping the core AI pipeline completely private. Ideal for organizations with strict data residency requirements.
