## What it is
Reasonix is an open-source AI coding assistant. The program runs on your computer; the AI model is a service you configure, which receives what it reads. You describe a task in plain language; it reads code, edits files and runs commands and tests inside the project folder you choose, and shows you each step.
You pick the model: a DeepSeek preset is built in, any OpenAI-compatible service is one config entry, and you pay the model provider directly.
## What you get
- **Read, edit, run.** It reads code, edits files and runs tests and commands, all inside your project folder.
- **Permission levels.** Have it ask every time, or let everyday actions run on their own; your forbid rules always hold. To see the approach first, use plan mode: it starts work only once you approve.
- **Rewind.** A file is saved before it changes, so you can rewind by conversation turn without touching your git history. Only files its edit tools changed are covered, not what a shell command did.
## 30-second start
Download, add a model key, open a project. New here? Start with the Studio desktop app.
1. Download and install the desktop app, Reasonix Studio, from the [releases page](https://github.com/esengine/DeepSeek-Reasonix/releases?q=studio-v&expanded=true).
2. Open it and enter your model provider and key when asked.
3. Open your project folder and write what you want, for example "add retry on failure to the http client".
4. At the level you chose, it stops and asks before anything that needs your say-so. Allow it to continue, or refuse.
Prefer a terminal? Download the `reasonix` command-line tool, run `reasonix setup` to pick a model, then run `reasonix`. See [Install](#install) and [Quick start](#quick-start).
## Four ways to use it
- **Desktop app (Studio).** A graphical app; the best place to start.
- **Terminal.** A full-screen text interface; `reasonix run "task"` also works in scripts.
- **Browser.** `reasonix web` opens a web interface on your own machine.
- **Editor.** Install the extension in VS Code; other editors that support ACP (Agent Client Protocol, a common way for an editor to connect to an AI assistant) can connect to `reasonix acp`.
All four are the same program underneath. What follows is for advanced users and contributors.
## Use it from DeepSeek Harness
DeepSeek Harness (`dsh`) can hand a task to Reasonix as a subagent over ACP. This repository publishes a plugin index for it:
1. Run `reasonix setup` on the machine that runs `dsh`. In the DSH Web UI turn on Custom plugin markets (Plugins, More) and add this index in the Discover tab: `https://raw.githubusercontent.com/esengine/DeepSeek-Reasonix/studio/integrations/dsh-plugin/market-index.json`
2. Install "Reasonix subagent" from it.
3. Open the plugin's page and turn its switch on. While it is off the model has no `reasonix` tool and may run `reasonix -p` in its own shell, which looks like a delegation and is not one.
Setup details, the permission policy and limits are in [Using Reasonix from DeepSeek Harness](./docs/DSH.md).
## Versions
Reasonix ships on two lines. See the [version roadmap announcement](https://github.com/esengine/DeepSeek-Reasonix/discussions/10748) for the reasoning behind the split.
| Line | Branch | Status | Get it |
| --- | --- | --- | --- |
| **Reasonix 2.x** | `studio` (this branch) | Active development | [Studio releases](https://github.com/esengine/DeepSeek-Reasonix/releases?q=studio-v&expanded=true) |
| **Reasonix 1.x** | [`main-v2`](https://github.com/esengine/DeepSeek-Reasonix/tree/main-v2) | Maintenance / stable | `npm i -g reasonix` · [desktop download](https://reasonix.io/?download=desktop#start) |
- **Want something stable?** Stay on 1.x. It keeps receiving bug fixes,
provider/API compatibility, updater and security fixes; its core architecture
is no longer being extended.
- **Want the new architecture?** Use 2.x Reasonix Studio. It is still moving
quickly; reports are welcome.
Valuable fixes, tests and behaviour from 1.x are reviewed one by one and ported
or reimplemented on 2.x where they fit the new architecture.
- [Moving from 1.x to 2.x](./docs/MIGRATING.md): what the two lines share, and
how to run both on one machine without losing sessions.
- [2.x roadmap](./docs/ROADMAP.md): what 2.x still has to deliver, how it ships,
and the decisions still open.
## Features
Technical highlights for advanced users.
- **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.** `CGO_ENABLED=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.
## Install
This branch is **Reasonix 2.x**. Its desktop app is Reasonix Studio; the CLI,
Studio, and editor integrations all run the same local Reasonix engine.
### Reasonix Studio (2.x)
Download the package for your platform from the latest
[Studio release](https://github.com/esengine/DeepSeek-Reasonix/releases?q=studio-v&expanded=true)
(tagged `studio-v2.*`; candidates such as `-rc.N` are marked as
pre-releases):
| Platform | Package | Architecture |
| --- | --- | --- |
| macOS | `.dmg` or `.zip` | Apple Silicon (`arm64`) / Intel (`amd64`) |
| Windows | Installer `-installer.exe` or portable `.zip` | x64 |
| Linux | `.deb`, `.rpm`, or `.AppImage` (download only) | x64 (`amd64`) / ARM64 (`arm64`, aarch64) |
Every package ships with a `.minisig` signature, and the release carries
`SHA256SUMS`. Once installed, Studio updates itself in place.
The same release also carries the 2.x `reasonix` CLI as archives for
`darwin|linux|windows × amd64|arm64`.
The Android build ships on that release as `ReasonixMobile-<version>.apk`
(`arm64`, Android 8.0 or newer). The kernel and the page run on the phone, and
the agent reaches your servers over SSH; pairing with a computer is done by
scanning the code it shows.
The APK is signed with the Android release key rather than minisign, so it
carries a `.sha256` and no `.minisig`.
When that key is absent the build is named
`ReasonixMobile-<version>-unsigned.apk`. Android refuses to install an unsigned
package, so those builds stay a workflow artifact for whoever wants to sign one,
and the release carries no APK at all.
### Reasonix 1.x (stable)
The 1.x CLI installs through npm on any supported platform, or Homebrew on
macOS:
```sh
npm i -g reasonix # any OS; pulls the prebuilt native binary
brew install esengine/reasonix/reasonix # macOS
```
The 1.x desktop app is on the
[official download page](https://reasonix.io/?download=desktop#start). Windows
installers are code-signed with a Certum code-signing certificate.
### VS Code extension
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. Install the 1.x CLI first.
- **VS Code:** [install from Visual Studio Marketplace](https://marketplace.visualstudio.com/items?itemName=SivanLiu.reasonix-agent)
- **VSCodium / Eclipse Theia:** [install from Open VSX Registry](https://open-vsx.org/extension/SivanLiu/reasonix-agent)
- **Extension ID:** `SivanLiu.reasonix-agent` · [source and usage guide](https://github.com/SivanCola/reasonix-vscode)
### Build from source
Clone the repository; `studio` builds 2.x and `main-v2` builds 1.x:
```sh
git clone https://github.com/esengine/DeepSeek-Reasonix.git
cd DeepSeek-Reasonix
git switch studio
```
#### CLI
The CLI build requires **Go 1.25+**. The module pins a `toolchain` directive;
keep `GOTOOLCHAIN=auto` so Go downloads the pinned toolchain, or install it.
```sh
make build # -> bin/reasonix(.exe)
make cross # -> dist/ (darwin|linux|windows × amd64|arm64)
```
#### Studio
Studio additionally requires **Node 24+ and pnpm 10**
(`npm install -g pnpm@10`) for the frontend.
```sh
make studio
```
See the [Studio build guide](desktop/README.md#prerequisites) for platform
webview dependencies and Linux build tags.
## Quick start
### Reasonix Studio
Install and launch Studio, then connect a provider and model in the app. No CLI
setup is needed.
### CLI / TUI
```sh
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.
For advanced CLI usage and configuration, see the **[CLI reference](./docs/CLI.md)**,
**[Guide](./docs/GUIDE.md)**, and
**[configuration paths](./docs/CONFIG_PATHS.md)**.
