DeepSeek reasonix, DeepSeek native coding agent with high caching and low cost

DeepSeek Reasonix is an open-source, MIT-licensed coding agent that runs locally as a single Go binary, offering four interfaces (terminal, desktop, browser, and editor integration) for autonomous code work. The tool prioritizes user control and auditability through features like per-turn checkpoints for undo capability, permission gating for each tool action, plan-before-execute mode, and a sandboxed workspace. It uses your own DeepSeek API key, supports extensibility via MCP (Model Context Protocol), and costs significantly less than traditional solutions.
