OpenCode Monitor

OpenCode Monitor is a desktop app for monitoring and interacting with OpenCode agents across multiple workspaces.

It is forked from CodexMonitor by Dimillian, adapted to use OpenCode's REST API + SSE backend while preserving CodexMonitor-shaped frontend event contracts.

OpenCode Monitor is an independent community project and is not affiliated with or endorsed by the OpenCode team.

Status

Active development — core REST/SSE support is live for thread/session lifecycle, event translation, messaging, model discovery, approvals, and image attachments. Remaining work is parity polish and OpenCode-specific UX cleanup.

Install

Download the latest packaged build from GitHub Releases.

Current release targets:

• macOS Apple Silicon
• Windows x64
• Linux x64 / arm64 (AppImage and rpm)

Requirements

1) OpenCode CLI (required)

OpenCode Monitor uses your local opencode CLI installation and manages its own local opencode serve process automatically. You do not need to start the server yourself.

Install OpenCode first:

# Recommended (macOS/Linux)
brew install anomalyco/tap/opencode

# Or npm
npm i -g opencode-ai@latest

Then verify the CLI:

opencode --version

2) Local tooling for development only

• Node.js 20+
• npm 10+
• Rust stable toolchain (cargo)

First Run

1. Install the opencode CLI and confirm opencode --version works in your terminal.

2. Launch OpenCode Monitor.

3. Open Settings -> OpenCode if you want to verify the managed server status. The app starts and monitors its own local OpenCode server, which defaults to http://127.0.0.1:14096.

4. Add a workspace and start a thread.

Development

To run from source:

npm install
npm run tauri:dev

Architecture

• Frontend: React 19 + Vite + TypeScript
• Backend: Tauri 2 (Rust)
• Protocol: OpenCode REST API + SSE, translated in Rust to CodexMonitor-shaped frontend events

Validation

npm run typecheck
npm run test
cd src-tauri && cargo check
cd src-tauri && cargo test

Release Build

npm run tauri:build
