Open source · MIT · a single Go binary A coding agent you can leave running. One local engine, four ways in, terminal, desktop app, browser, or your editor over ACP.

[!IMPORTANT] Community · 加入社区, bilingual Discord for setup help (#help / #求助), workflow showcases, and feature ideas. Config-driven. Providers, the agent, enabled tools, and plugins are all declared in reasonix.toml. No hardcoded models. Multi-model & composable. DeepSeek ships as a preset; any OpenAI-compatible endpoint is a config entry, not new code. Optionally run two models together (executor + planner) in separate, cache-stable sessions. Plugin-driven. MCP servers contribute tools, prompts, and resources; Extension Protocol v1 sidecars can also intercept runtime events, contribute Providers and structured UI, and ship versioned plugin packages. Cache-aware context maintenance. Startup injects a small stable environment summary, stale tool output is snipped/pruned before summary compaction, and the built-in tool schema contract is documented for regression review. Zero-friction distribution. CGOENABLED=0 single binary; cross-compile to six targets with one command. The result is a fully self-contained static binary, nothing to install on the target machine beyond the binary itself. Choose the path that matches how you want to use Reasonix. The CLI/TUI, desktop app, and VS Code extension all use the same local Reasonix engine.
