Features

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. External tools run as subprocesses over stdio JSON-RPC (MCP-compatible). Built-in tools self-register at compile time.
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. CGO_ENABLED=0 single binary; cross-compile to six targets with one command. The only dependency is a TOML parser.

Install

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.

Path A: CLI / TUI

Install the native binary through npm on any supported platform, or use Homebrew on macOS:

npm i -g reasonix                  # any OS; pulls the prebuilt native binary
brew install esengine/reasonix/reasonix   # macOS

Prebuilt archives (darwin|linux|windows × amd64|arm64) and SHA256SUMS are on every GitHub release.

Path B: Desktop app

Use the official download page for the latest desktop build.

Platform	Package	Architecture
macOS	Universal `.dmg` or `.zip`	Apple Silicon / Intel
Windows	Installer `.exe` or portable `.zip`	x64 / ARM64
Linux	`.deb` or `.tar.gz`	x64

Windows installers are code-signed through SignPath.io with a free certificate provided by the SignPath Foundation.

Path C: VS Code extension

Complete Path A first. The extension does not bundle the CLI; it starts your local reasonix acp backend and adds native chat, editor context, tool-call approvals, model selection, and workspace sessions.

VS Code: install from Visual Studio Marketplace
VSCodium / Eclipse Theia: install from Open VSX Registry
Extension ID: SivanLiu.reasonix-agent · source and usage guide

Path D: Build from source

git clone https://github.com/esengine/DeepSeek-Reasonix.git
cd DeepSeek-Reasonix
make build      # -> bin/reasonix(.exe)
make cross      # -> dist/ (darwin|linux|windows × amd64|arm64)

Quick start

CLI / TUI

These commands are for the CLI/TUI installed through Path A:

reasonix setup                      # configure a provider and model
reasonix                            # start an interactive session
reasonix run "implement the TODOs in main.go"

In an interactive session, run /init when you want Reasonix to create project instructions.

Desktop app

Download the installer for your platform from the official download page, install and launch Reasonix, then configure a provider and model in the app. The CLI commands above are not required for the desktop app.

For advanced CLI usage and configuration, see the CLI reference, Guide, and configuration paths.
