DeepSeek-Reasonix

The DeepSeek-native terminal coding agent.

Designed around prefix-cache stability, so it can grind through long-running tasks unattended. The npm TypeScript line is now legacy; main development has moved to Go.

34,683 star Reasonix Desktop v1.27.0 Terminal agent / CLI GitHub

Install

Node >= 22 (npm install path); building from source needs Go 1.25+, and the desktop build needs Node 24+ with pnpm 10; a paid DeepSeek API key is required (no offline or free option). Known pitfalls: the current npm TypeScript line (Reasonix 0.x) is legacy and receives bug fixes only, since main development has moved to a Go rewrite (main-v2 branch); switching directories mid-session is not supported (by design); DeepSeek only, not multi-provider.

An npm package: install it globally once, or run it with npx without installing.

npm i -g reasonix

npm install -g reasonix reasonix code my-project

cd my-project npx reasonix code

Short alias

npm install -g dsnix npx dsnix@latest code

macOS HomebrewmacOS

brew install esengine/reasonix/reasonix

Desktop: official download page — macOS (.dmg/.zip) / Windows (.exe / portable .zip) / Linux (.deb/.tar.gz)WindowsmacOSLinux

VS Code: install from the marketplace, extension ID SivanLiu.reasonix-agent

Build from source (Go 1.25+)Windows

make build # 产出 bin/reasonix(.exe) make cross # 跨平台二进制

Full tutorial

01Confirm Node >= 22 (macOS/Linux/Windows), then install globally or run through npx

02Request a DeepSeek API key at platform.deepseek.com/api_keys (paid)

03Paste the API key on first run and it is stored persistently; or run reasonix setup to configure provider/model

04reasonix opens an interactive session, or reasonix run "implement the TODOs in main.go" for a one-shot run

05reasonix doctor for a health check, reasonix update to upgrade, reasonix code --help for every flag

config

配置位置：~/.reasonix/config.json（全局）+ <project>/.reasonix/（项目级覆盖）；Go 版为 reasonix.toml（providers/agent/tools）。README 未给出完整配置文件示例片段。

Features

·Cache-aware context maintenance: designed around prefix-cache stability, suited to long unattended runs

·Pluggable: MCP servers + Extension Protocol v1, configuration-driven (providers/agent/tools)

·Multiple distribution forms: CLI/TUI, desktop app, VS Code extension, and a single static binary

DeepSeek-Reasonix Now this is the kind of harness I can get behind! Built for the poor API users, all around cache hits even has a GUI (wrapper) already @victor207755822 take ideas or collaborate idk

Reasonix 真的很优秀，不要被它的项目名字（DeepSeek-Reasonix）所误导了，只要中转站支持 OpenAI-compatible 都可以支持...再次推荐。主要是它的技能、记忆、Hooks、MCP等功能都很好用...它被我用于替代OpenCode 了

Reasonix is genuinely excellent — don't be misled by the project name (DeepSeek-Reasonix); any relay endpoint with OpenAI-compatible support will work... Recommending it again. Its skills, memory, Hooks, MCP and other features are all great to use... I've made it my OpenCode replacement.

I am using it with the tui plugin which was added 2 days ago or so. It is great comparing to reasonix as it handles permissions much better and in general output seems to be more concise and def more consistent.

Are these reasonx bots? All 3 posted in the same minute, all have low karma, and I've genuinely never heard of reasonx before now lol
