<p align="center">
A self-hosted multi-agent AI platform that orchestrates specialized agents across Telegram, WhatsApp, and a web dashboard — with 100+ tools, 15 autonomous data scrapers, vector memory, and cron scheduling.
</p>

---

## What Can OpenCrow Do?

- **Run AI agents** on Telegram, WhatsApp, and web — each with its own persona, model, tools, and memory
- **Scrape data sources** autonomously — HackerNews, Reddit, GitHub, X/Twitter, App Store, Play Store, news, and more
- **Remember everything** — conversations, facts, and observations are indexed into vector memory and recalled across sessions
- **Generate ideas** — research agents collect signals, ideation agents synthesize them into product/crypto/AI startup ideas on a schedule
- **Automate with cron** — schedule any agent to run at intervals, one-shot times, or cron expressions
- **Self-manage** — agents can deploy code, restart processes, manage other agents, and monitor system health
- **Scale horizontally** — each agent, scraper, and subsystem runs as an isolated process with crash recovery

---

## Architecture

OpenCrow runs as a thin core process that spawns and supervises isolated child processes. Each subsystem (agents, scrapers, web, cron) runs independently with crash-loop detection, exponential backoff, and automatic recovery.

```
core (orchestrator + internal API)
  └── spawns:
      ├── cron                       (scheduled jobs + agent execution)
      ├── web                        (React dashboard + Hono API)
      ├── agent:default              (Telegram + WhatsApp channels)
      ├── agent:<id>                 (per-agent Telegram/WhatsApp bots)
      └── scraper:<id>               (one per data source, isolated)
```

- **Process isolation** — Kill a scraper, everything else keeps running. Crash one agent, others are unaffected.
- **Dynamic scaling** — Agents and scrapers are added/removed via config. The orchestrator reconciles desired vs actual state every 5 seconds.
- **Monolith mode** — For development, `src/gateway.ts` runs everything in a single process.

## Stack

| Layer | Technology |
|-------|-----------|
| Runtime | [Bun](https://bun.sh) |
| AI | Claude Agent SDK (`@anthropic-ai/claude-agent-sdk`) via MCP bridge |
| Web Framework | Hono |
| Frontend | React SPA (TSX + CSS bundled by Bun HTML imports) |
| Database | PostgreSQL (`Bun.sql` tagged templates) |
| Vector Search | Qdrant |
| Telegram | grammY |
| WhatsApp | Baileys |
| Embeddings | OpenRouter (`text-embedding-3-small`, 512 dims) |

## Agent System

Agents are the core of OpenCrow. Each agent is an AI persona with its own system prompt, model, tools, and channel connections.

### How agents work

1. Message arrives via Telegram/WhatsApp/Web
2. Router checks authorization, resolves which agent handles the chat
3. Agent SDK spawns a Claude Code subprocess with the agent's system prompt
4. OpenCrow tools are exposed via an in-process MCP server (no network hop)
5. Agent iterates: thinking → tool use → response, auto-continuing until done
6. SDK session ID is captured and resumed on next message for conversational continuity
7. Observations are extracted from the conversation and indexed into memory

### Agent features

- **Session resume** — Conversations persist across messages via SDK session IDs
- **Cross-session memory** — Related memories and user preferences are injected into prompts
- **Auto-continuation** — Agents keep working when they have pending tool use, unlimited iterations
- **Sub-agent spawning** — Agents can spawn specialized sub-agents for complex tasks
- **Activity logging** — Real-time progress shown as an editable Telegram message with tool tracking
- **Hot-reload** — Agent configs stored in DB (`config_overrides` table), reloaded every 30 seconds
- **Agent templates** — Predefined templates (chatbot, researcher, coder, etc.) for quick agent creation
- **Tool filtering** — Per-agent allowlist/denylist controls which tools are available
- **Intelligent tool routing** — Tools are ranked by category match, recency, success rate, and keyword relevance

### Built-in sub-agents

31 specialized agents for orchestrated workflows:

### Orchestration workflow

```
TRIVIAL task   → Agent answers directly
MODERATE task  → Agent states plan, executes
COMPLEX task   → Agent spawns sub-agents:
                 planner → user approval → backend/frontend → reviewer → security-reviewer
```

- **Anti-detection** — Stealth scripts, cookie auth, GraphQL API interception for X/Twitter
- **Multi-account** — Reddit, Product Hunt support multiple accounts with separate cookies

- **Rate limiting** — Per-source delays (App Store: 2s between calls)

### X/Twitter automation

The X/Twitter scraper is a full automation suite:

- **Timeline scraping** — Capture tweets from your home timeline via GraphQL interception
- **Bookmark sharing** — Share bookmarked tweets to configured Telegram chats
- **Auto-like** — Automatically like tweets matching configured criteria
- **Auto-follow** — Follow users based on interaction patterns
- **Interaction tracking** — Track likes, retweets, replies across accounts

## Memory & RAG

Hybrid search engine combining vector similarity and full-text search for long-term agent memory.

### Search pipeline

1. **Query expansion** — Semantic expansion with synonyms and related terms
2. **Parallel search** — Vector (Qdrant) + full-text (PostgreSQL) run concurrently
3. **Score merging** — 70% vector weight + 30% full-text weight
4. **Temporal decay** — Per-kind half-life (observations decay faster than documents)
5. **MMR deduplication** — Maximal marginal relevance to reduce redundancy
6. **Channel scoping** — Conversation memories stay within their channel

### Memory types

Source kinds, each with its own chunk profile and temporal decay: conversations, notes, documents, tweets, articles, products, stories, Reddit posts, GitHub repos, observations, ideas, app reviews, and app rankings.

### Observation extraction

After each conversation, observations (facts, preferences, patterns) are automatically extracted and indexed. These are injected into future prompts for cross-session context.

## Channels

Plugin-based channel system with a unified adapter interface.

### Telegram
- grammY-based with serial polling (no runner — avoids 409 conflicts)
- Per-chat message queuing via sequentialize middleware
- Activity log: editable message showing real-time tool progress
- Smart message chunking for 4096 character limit
- HTML formatting with inline buttons

### WhatsApp
- Baileys (Web WhatsApp protocol)
- QR code / pairing code authentication
- Per-number and per-group sender filtering
- Media support (images, documents)

### Web Chat
- Hono API route (`POST /api/chat`)
- Bearer token auth via `OPENCROW_WEB_TOKEN`

### Router

The message router handles authorization, agent selection, and response delivery:

- **Authorization** — Per-channel allowed senders (userIds for Telegram, numbers for WhatsApp)
- **Agent selection** — Explicit `/agent` command > persistent routing rules > default agent
- **Commands** — `/stop` (abort), `/clear` (reset session), `/status` (health), `/agent [id]` (switch)
- **Concurrency** — One active message per chat, prevents overlapping processing
- **Input validation** — Per-agent max input length enforcement

## Cron Scheduler

Agents can be triggered on schedules for autonomous work.

### Schedule types

- **`at`** — One-time execution at a specific timestamp
- **`every`** — Interval-based (e.g., every 6 hours)
- **`cron`** — Standard cron expressions via croner

### Built-in jobs

- **Idea generation** — Research agents save signals, ideation agents synthesize them (every 6 hours)
- **Watchdog** — Health monitoring: processes, errors, cron success, costs, DB, scrapers (every 30 minutes)
- **Digests** — Scheduled content summaries

### Execution

Jobs run agents with full tool access in isolation. Progress is tracked per-run with status, duration, and result summaries stored in the database.

## Web Dashboard

React SPA served via Bun HTML imports with Hono API backend. 30+ views covering every subsystem.

### Auth

`OPENCROW_WEB_TOKEN` environment variable → Bearer token in localStorage → 401 shows login modal.

## Quick Start

```bash
curl -fsSL https://opencrow.dev/install.sh | bash
opencrow setup
```

The setup wizard handles everything: Docker containers, database, `.env`, Telegram/WhatsApp, and service installation.

```bash
opencrow doctor     # Check system health
opencrow update     # Pull latest + reinstall + restart
opencrow status     # Show running service status
opencrow start      # Start in foreground (monolith mode)
opencrow version    # Show version info
```

## Manual Setup

### Prerequisites

- [Bun](https://bun.sh) runtime
- **macOS (native path):** Homebrew — `postgresql@17` and `python@3.11`; [Ollama](https://ollama.com) for embeddings
- **Linux / server path:** Docker (PostgreSQL + Qdrant run in containers)
- Claude Agent SDK credentials (`~/.claude/.credentials.json`)

### Install

```bash
bun install
cp .env.example .env
```

### Environment variables

```bash
# Required
OPENCROW_WEB_TOKEN=...                    # Web dashboard auth token
TELEGRAM_BOT_TOKEN=...                    # Telegram bot token from BotFather
OPENROUTER_API_KEY=...                    # For embeddings (text-embedding-3-small)
DATABASE_URL=postgres://opencrow:changeme@127.0.0.1:5432/opencrow

# Optional
QDRANT_URL=http://127.0.0.1:6333         # Vector search (defaults to this)
OPENCROW_WEB_HOST=127.0.0.1              # Web UI bind address
OPENCROW_WEB_PORT=48080                  # Web UI port
```

### Start services

#### Native macOS (default local)

Install prerequisites via Homebrew and pull the embeddings model:

```bash
brew install postgresql@17 python@3.11
ollama pull nomic-embed-text
```

Provision and start all four services (Postgres, Qdrant, mem0, app) via launchd:

```bash
bun run src/cli.ts native up
```

Verify everything is healthy:

```bash
bun run src/cli.ts doctor
```

#### Docker (Linux server deploy)

For a Linux server or any non-macOS host, use Docker Compose instead:

```bash
docker compose up -d    # PostgreSQL + Qdrant
```

### Run

```bash
# Development (monolith, single process)
bun run dev

# Production (distributed, process tree)
bun run start
```

## Development

```bash
bun run dev           # Watch mode (monolith)
bun run dev:web       # Web UI only
bun test              # Run tests
bun run typecheck     # TypeScript check
bun run tw            # Tailwind CSS watch
bun run tw:build      # Tailwind CSS build
```

## Deployment

### systemd

```bash
bun run service:install    # Install opencrow.service
bun run service:start      # Start
bun run service:stop       # Stop
bun run service:restart    # Restart
bun run service:status     # Check health
```
