Telegram (Recommended)

Easiest setup. Just need bot token from @BotFather.

# 1. Create bot with @BotFather on Telegram
# 2. Get your user ID from @userinfobot

{
  "channels": {
    "telegram": {
      "enabled": true,
      "token": "YOUR_BOT_TOKEN",
      "allow_from": ["YOUR_USER_ID"]
    }
  }
}

# 3. Run gateway
picoclaw gateway

Discord

Easy setup. Enable MESSAGE CONTENT INTENT.

# 1. Create bot at discord.com/developers/applications
# 2. Enable MESSAGE CONTENT INTENT
# 3. Get your User ID (Settings → Advanced → Developer Mode)

{
  "channels": {
    "discord": {
      "enabled": true,
      "token": "YOUR_BOT_TOKEN",
      "allow_from": ["YOUR_USER_ID"],
      "mention_only": false
    }
  }
}

Security Sandbox

PicoClaw runs in a sandboxed environment by default. File and command access is restricted to the workspace directory.

Protected Operations

✓ read_file — Workspace only
✓ write_file — Workspace only
✓ list_dir — Workspace only
✓ exec — Path must be in workspace

Blocked Commands

✗ rm -rf, del /f
✗ format, mkfs
✗ dd if= (disk imaging)
✗ shutdown, reboot

Note: Subagents and heartbeat tasks inherit the same workspace restrictions. There's no way to bypass security through subagents or scheduled tasks.

Heartbeat (Periodic Tasks)

Automate recurring tasks with HEARTBEAT.md. The agent checks this file every 30 minutes (configurable) and executes tasks.

# Create HEARTBEAT.md in workspace
# ~/.picoclaw/workspace/HEARTBEAT.md

# Quick Tasks (respond directly)
- Report current time
- Check system status

# Long Tasks (use spawn for async)
- Search the web for AI news and summarize
- Check email and report important messages
- Monitor website uptime

# Configuration
{
  "heartbeat": {
    "enabled": true,
    "interval": 30
  }
}

Quick Tasks

Execute directly and respond immediately. Good for status checks and simple reports.

Spawn (Async)

Create subagents for long-running tasks. Non-blocking, subagent reports directly to user.

Perfect For

Edge & IoT Devices

Run on $9.9 LicheeRV-Nano, NanoKVM, MaixCAM, or any RISC-V/ARM board. <10MB RAM requirement makes it perfect for constrained environments.

Old Android Phones

Give your decade-old phone a second life! Run via Termux with simple setup. Turn e-waste into smart assistants.

Low-Cost VPS

Run on the cheapest cloud instances. Minimal resource usage means lower bills. Perfect for always-on personal assistants.

FAQ

What makes PicoClaw different from OpenClaw? ▼

PicoClaw is written in Go and designed for extreme efficiency: <10MB RAM vs >1GB for OpenClaw, <1s boot vs >500s, runs on $10 hardware vs $599 Mac Mini. It's 99% smaller in memory and 98% cheaper.

Which LLM providers does PicoClaw support? ▼

PicoClaw supports 15+ providers including OpenAI, Anthropic, Zhipu (GLM), DeepSeek, Google Gemini, Groq, Moonshot, Qwen, NVIDIA, Ollama (local), OpenRouter, VLLM, Cerebras, and more. New providers can be added with zero code changes using vendor/model format.

Can I run PicoClaw on a Raspberry Pi? ▼

Yes! PicoClaw is designed for low-cost hardware. It runs on $9.9 LicheeRV-Nano, $30-50 NanoKVM, $50 MaixCAM, old Android phones via Termux, and any Linux board. It requires <10MB RAM and boots in <1s even on 0.6GHz single core.

What chat apps does PicoClaw support? ▼

PicoClaw supports 6 chat apps: Telegram (recommended), Discord, QQ, DingTalk, LINE, and WeCom (企业微信). Each requires bot token/credentials setup. Telegram and Discord are easiest, LINE and WeCom require webhook configuration.

How does the security sandbox work? ▼

PicoClaw runs in a sandboxed environment by default. When restrict_to_workspace is true (default), file and command access is limited to the workspace directory. Dangerous commands like rm -rf, format, dd, shutdown are blocked. Subagents and heartbeat tasks inherit the same restrictions.

What is the Heartbeat feature? ▼

Heartbeat enables periodic tasks. Create a HEARTBEAT.md file in your workspace with tasks to execute every 30 minutes (configurable). For long-running tasks, use the spawn tool to create async subagents. This allows automated monitoring, reporting, and scheduled actions.

How do I enable web search? ▼

PicoClaw supports Brave Search, Tavily, and DuckDuckGo. DuckDuckGo requires no API key and works out of the box. For better results, get a free Brave Search API key (2000 queries/month) or Tavily key (1000 queries/month). Configure in ~/.picoclaw/config.json under tools.web.

Which Should You Choose?

Choose PicoClaw If...

Troubleshooting

# Build issues
make deps  # Install Go dependencies

# Permission errors
sudo usermod -aG docker $USER  # For Docker
# Then logout and login

# Telegram conflict (multiple instances)
# Ensure only one 'picoclaw gateway' is running

# Content filtering errors
# Some providers (Zhipu) have content filters
# Try rephrasing or use different model

# Reset everything
rm -rf ~/.picoclaw
