What is ZeroClaw?
ZeroClaw is an open-source AI agent runtime that ships as a single native Rust binary with no Node, JVM, or Python environment required, starting in milliseconds and running on hardware as small as a Raspberry Pi. It connects to 70+ LLM providers, from local Ollama and llama.cpp models to Anthropic and OpenAI, with automatic fallback routing between them, and reaches users through 30+ channels including Telegram, Discord, WhatsApp, Slack, Signal, iMessage, Matrix, and email.
It acts through tools such as shell, browser, HTTP, and hardware peripherals (ESP32, Arduino, Raspberry Pi), and can cryptographically sign tool-call receipts. There is no hosted tier or subscription; users pay only their own model provider costs, or nothing with a fully local model.
Key features
- Single native Rust binary, no runtime dependencies, starts in milliseconds
- Connects to 70+ LLM providers with automatic fallback between them
- Reaches 30+ channels: Telegram, Discord, WhatsApp, Slack, Signal, iMessage, Matrix, email, and more
- Acts through shell, browser, HTTP, and hardware tools (ESP32, Arduino, Raspberry Pi)
- Cryptographic receipts can stamp every tool call for auditability
- Runs on ARM and x86, down to a Raspberry Pi, with no cloud dependency required
How to get started
- Install with the one-line curl script, Homebrew, or Docker
- Point it at a local model (via Ollama) or add your own API key
- Connect the chat channels you want it to reach you on
- Configure which tools (shell, browser, hardware) it's allowed to use
- Message it from any connected channel to start delegating tasks
ZeroClaw pricing
ZeroClaw is completely free and open source, dual-licensed under MIT and Apache 2.0. There is no subscription or hosted seat; the only cost is whatever LLM provider you connect, or nothing if you run a local model via Ollama.
| Plan | Price | Best for |
|---|---|---|
| Free / Open Source | $0 | All users, self-hosted on their own machine |
Our take: Its standout trait is sheer minimalism — a single Rust binary with no runtime dependencies that starts in milliseconds and can run on a Raspberry Pi, a very different tradeoff from Electron-based agent apps.

Use cases
- Developers wanting a personal agent that costs nothing beyond model API fees
- Hobbyists running an AI agent on a Raspberry Pi or other small hardware
- Privacy-focused users who want everything running on their own machine
- Builders wanting an agent that bridges to physical hardware (IoT boards)
ZeroClaw vs. alternatives
| Tool | How it compares |
|---|---|
| ZeroClaw | A lightweight, single-binary personal AI agent written in Rust that runs on your own hardware, with your own keys, and reaches 30+ chat channels. |
| Hermes Agent | Hermes Agent adds a self-improving skill-learning loop that ZeroClaw's minimalist runtime doesn't focus on. |
| AnythingLLM | AnythingLLM adds a document-chat/RAG interface on top of agents, which ZeroClaw's lean runtime does not include. |
| AgentGPT | AgentGPT runs in the browser as a hosted service rather than as a self-hosted native binary. |
