OpenWorker is an open-source AI coworker that delivers finished work, not just chat — a polished document, a Slack reply with the numbers, an updated calendar, a triaged inbox.

Ask it to prepare a customer brief, untangle your week, draft a report, or check where a release stands across Jira and GitHub. It works across your files and everyday tools, produces the deliverable, and checks in before doing anything consequential.

It runs on your machine and doesn't lock you into any model: bring your own API key for OpenAI, Anthropic, Google, or an open-weight provider — or run fully local with Ollama. Your data leaves your machine only through the model and integrations you choose.

⬇ macOS (Apple Silicon) _{macOS 12+ · signed & notarized · auto-updates}

Open the app, add a model key (or point it at Ollama), and ask for something real.

What it can do

Produce real deliverables — documents, spreadsheets, reports, and web pages land as files you can open and share, not text in a chat window.
Work from Slack — mention @OpenWorker in a channel; a session opens on your desktop, the work happens with your tools, and the answer comes back as a thread reply.
Use your everyday tools — 25+ integrations including GitHub, Slack, Jira, Notion, Linear, HubSpot, Outlook, monday.com, Gmail, and Google Calendar, plus your terminal and local files. Remote MCP servers plug in too, with per-tool control.
Run on a schedule — automations for recurring work: a morning brief, a weekly report, a standing watch over a channel. Runs land in the app with full transcripts.
Ask before acting — writes, sends, and shell commands are approval-gated. Unattended runs park their asks in an inbox instead of acting on their own.

Bring your own model

Model access is yours: pick a provider, paste your key, switch anytime. Supported out of the box:

OpenAI · Anthropic · Google Gemini · GLM (Z.ai) · DeepSeek · Kimi (Moonshot) · Qwen · MiniMax · Mistral · Grok (xAI) — plus open-weight models via Together and Fireworks, and fully local models via Ollama.

A curated model list marks what we've verified for tool-calling work; any model string works at your own risk. Keys are stored locally and are only ever sent to the vendor they belong to.

How it works

┌────────────────────────────────────────────────┐
│              OpenWorker desktop app            │  native shell + GUI
├────────────────────────────────────────────────┤
│           local agent server (Python)          │  engine · tools · connectors — built on aisuite
├───────────────┬────────────────┬───────────────┤
│  your files   │   your tools   │  your model   │  everything runs with your keys,
│  & terminal   │ 25+ connectors │  any provider │  on your machine
└───────────────┴────────────────┴───────────────┘

Everything — the agent loop, your conversations, connector tokens, model keys — lives on your machine. A small cloud service exists only to make connector OAuth one-click; the tokens it brokers are handed straight back to your device and stored locally. No account is required: every connector also accepts manually-created credentials, and the app is fully usable signed out.

Run from source

git clone https://github.com/andrewyng/openworker
cd openworker
bash packaging/setup_dev_env.sh          # creates .venv and installs the package

# terminal 1 — the local agent server
.venv/bin/openworker-server --cwd ~/some/project --port 8765

# terminal 2 — the GUI (browser dev mode)
cd surfaces/gui && npm install && npm run dev

Tests: .venv/bin/pytest (server), npm test and npm run e2e in surfaces/gui (GUI unit + hermetic end-to-end). Desktop bundles are built with packaging/build_dmg.sh / packaging/build_windows.ps1. Design notes and specs live in docs/.

Built on aisuite

OpenWorker's engine is built on aisuite — a lightweight Python library providing a unified chat-completions API across LLM providers and an agents layer with tools, toolkits, and MCP support. If you want to build your own agent harness rather than use ours, start there; this repo is a working reference for what aisuite can carry.

OpenWorker was originally developed inside the aisuite repository before moving to its own home here — thanks to the aisuite contributors whose work it builds on.
