How OpenClaw works

OpenClaw is the most-starred open-source personal assistant on GitHub, with roughly 380,000 stars on the openclaw/openclaw repository. Started by Peter Steinberger and now governed by the non-profit OpenClaw Foundation, it inverts the usual assistant model: instead of a hosted product you log into, it installs on your own machine with a curl one-liner and reaches you through the chat apps you already use — 29 channels including WhatsApp, Telegram, Slack, Signal, Discord, and iMessage.

In practice it behaves less like a chatbot and more like a resident process: it holds persistent memory of your projects and people, controls a browser, reads and writes local files, and works email and calendar tasks. It is model-agnostic, so you connect Claude, GPT, or another provider with your own key and pay only that usage. The trade-off is ownership — there is no vendor handling uptime, updates, or the security of an agent with deep access to your machine.

What people use OpenClaw for

An assistant in your existing chat apps

Message it on WhatsApp, Telegram, Slack, or iMessage instead of opening yet another dashboard.

Inbox and calendar triage

Have it sort mail, draft replies, and manage calendar entries on a schedule rather than on demand.

Private, local automation

Run browser and file tasks on your own machine so account state and documents never reach a vendor cloud.

OpenClaw FAQ

Is OpenClaw free?

Yes. The project is free and open source, governed by the non-profit OpenClaw Foundation. Your only cost is the LLM API usage of whichever model you connect, such as Claude or GPT.

How do you install OpenClaw?

A single curl one-liner from openclaw.ai installs it on macOS, Linux, or Windows. It then runs on your own machine, and its state and memory stay there rather than in a hosted account.

What can OpenClaw actually do?

It handles email, calendars, browser control, and local files, and it remembers your projects and preferences across conversations. It reaches you through 29 chat channels and can be extended with community-built skills.

Is OpenClaw safe to run?

It needs broad system and browser access to be useful, so permissions deserve care. Because it is self-hosted and open source you can audit exactly what it does, but you also own the security of the machine it runs on.
