openweavr/Openweavr: Self-hosted workflow automation with AI Agents

Self-hosted workflow automation with AI agents.
Weave your workflows together.

Weavr connects AI agents with your developer tools—GitHub, Linear, Notion, Slack, databases, CI/CD, and more. Think Zapier/n8n, but with native AI agent support and full data sovereignty.

• 🏠 Self-hosted — Your workflows, your data, your infrastructure
• 🤖 AI Agents — Autonomous agents with web search, tool use, and multi-step reasoning
• 🔌 Plugin ecosystem — Extensible integrations for any tool
• 📡 Real-time — WebSocket-powered event streaming
• 🎯 DAG execution — Parallel steps, retries, error handling
• 🖥️ CLI + Web UI — Terminal power users and visual builders welcome
• 💬 Messaging — Built-in WhatsApp, Telegram, and iMessage support

2. Choose “Data for Search” plan (2,000 free queries/month)
3. Add your API key in Settings or set BRAVE_API_KEY environment variable

You can override the scheduler database location in ~/.weavr/config.yaml:

scheduler:
  dbPath: /path/to/scheduler.db

import { definePlugin, defineAction } from 'weavr/plugins';

export default definePlugin({
  name: 'my-plugin',

  actions: [
    defineAction({
      name: 'greet',
      execute: async (ctx) => {
        const name = ctx.config.name as string;
        ctx.log(`Hello, ${name}!`);
        return { greeted: name };
      },
    }),
  ],
});
