The open-source platform for task-driven autonomous AI.
Every task becomes an autonomous agent — campaigns, reports, features, audits
ship in parallel. For every team.
How It Works · Features · Quick Start · Architecture · Contributing
| Step | What happens |
|---|---|
| Create | Write a task, not a prompt. Describe the deliverable — a campaign, a report, a feature, an audit. OpenCow links full context: project files, prior work, related tasks. |
| Dispatch | One task, one agent. Each task gets a dedicated agent with full context — project knowledge, team playbooks, organizational standards. 15 tasks, 15 agents, in parallel. |
| Deliver | Agents research, draft, build, and publish — autonomously. Real-time progress, instant notifications, approval gates at every step. Review. Ship. |
Everything to turn your task list into a parallel AI workforce.
|
Built-in task tracker where every task becomes an agent. Break projects into sub-tasks, each with a dedicated agent. Your task list IS your delivery plan.
|
Equip agents with your org's knowledge, standards, and tools. Skills, playbooks, integrations — every agent follows your processes.
|
|
Real-time dashboard. Track every agent's progress and actions. Approve deliverables. One screen, full visibility.
|
Dispatch agents from Telegram, Discord, WeChat, or Lark. Schedule recurring workflows. Get notified via webhooks.
|
No plugins. No integrations to configure. Every capability your AI workforce needs.

Command & Control
|
The design decisions that define OpenCow.
| Principle | What it means | |
|---|---|---|
| 1:1 | Task → Agent | One task, one agent. Full context. Full traceability. Zero ambiguity. |
| ✅ | Local & Private | Everything runs on your machine. Zero telemetry. Zero cloud. Your data never leaves. |
| 15+ | Parallel Agents | Deliver 15+ tasks simultaneously. Suspend and resume any agent without losing context. |
| 4-Layer | Deep Context Engine | Every agent inherits organizational knowledge, project context, team standards, and task-specific instructions. |
Prerequisites: Node.js >= 18 and pnpm >= 9

| Layer | Choice | Why |
|---|---|---|
| Desktop | Electron 40 | Cross-platform, native-grade experience |
| UI | React 19 + Tailwind CSS 4 | Concurrent rendering, utility-first styling |
| Language | TypeScript (strict, zero any) |
End-to-end type safety |
| State | Zustand | Lightweight reactive stores with row-level subscriptions |
| Build | electron-vite (Vite) | Sub-second HMR, triple-target build |
| Database | SQLite via Kysely | Local-first, type-safe schema with 35+ migrations |
| Terminal | xterm.js + WebGL | Hardware-accelerated terminal rendering |
| Editor | Monaco Editor | VS Code-grade editing experience |
| Testing | Vitest + React Testing Library | Fast, modern test runner |
| AI | Claude Agent SDK + Codex SDK + MCP | Multi-engine — choose Claude or Codex as your AI engine, with Model Context Protocol |
OpenCow follows a hardened Electron architecture with strict process isolation:

Security model:
contextIsolation: true— renderer cannot access Node.jsnodeIntegration: false— no direct module loading- Type-safe IPC bridge via
contextBridge.exposeInMainWorld - Sandboxed file access with explicit path allowlists
- Separate data directories for dev (
~/.opencow-dev) and production (~/.opencow)

electron-vite compiles three independent TypeScript targets:
| Target | Entry | Output |
|---|---|---|
| Main | electron/main.ts |
out/main/ |
| Preload | electron/preload.ts |
out/preload/ |
| Renderer | src/renderer/index.html |
