> *What if your AI assistant ran on your own server — and you could reach it from any chat app you already use?*
That’s the premise behind OpenClaw, and once it clicks, it’s hard to go back to the subscription treadmill.
Most of us got used to AI assistants through ChatGPT or Claude.ai: open a browser tab, type a question, wait for an answer. It works, but it comes with trade-offs you don’t always notice until they start to sting — your conversations are stored on someone else’s servers, your monthly bill scales with usage, and you’re locked into whatever the platform decides to offer. If you’ve ever thought *”I wish this just lived on my own machine”*, OpenClaw is for you.
What Is OpenClaw?
OpenClaw is a self-hosted AI gateway — a piece of software you run on your own hardware (a laptop, a Linux server, a VPS, or even a Raspberry Pi) that bridges your favorite chat apps with an AI agent you control.
In plain English: you install OpenClaw once, point it at an AI provider of your choice (Anthropic, OpenAI, etc.) using your own API keys, and then you get a personal AI assistant you can message from WhatsApp, Telegram, Discord, iMessage, Signal, or Slack — wherever you already spend your time. No extra app to install. No new subscription. No data leaving your machine unless you explicitly tell it to.
It’s MIT-licensed and open source, which means you can read every line of code, modify it, and run it without asking permission.
How It Works: Gateway → Channels → Skills
OpenClaw has three moving parts, and once you understand them, the whole system makes sense.
1. The Gateway
The Gateway is the heart of OpenClaw. It’s a single long-running process that you start on your machine:
openclaw gateway startOnce it’s running, it handles authentication, session management, routing between channels, and communication with the AI model. Think of it as the switchboard that keeps everything talking to everything else.
2. Channels
Channels are the chat apps you already use. OpenClaw connects to them and listens for your messages. You configure the channels you want, and the Gateway handles the rest — you don’t need a separate app or dashboard open to interact with your AI.
3. Skills (AgentSkills)
Skills are modular capabilities you install on top of OpenClaw. They give your AI agent new powers — from checking the weather to controlling smart home devices to transcribing voice notes. More on these in a moment.
Channels: Talk to Your AI From Anywhere
One of OpenClaw’s most practical features is the sheer number of channels it supports out of the box. You’re not forced onto a new platform — you meet your AI where you already are.
Core built-in channels include:
- Telegram — the fastest to set up (just a bot token). Great starting point.
- WhatsApp — the most popular globally; uses QR pairing.
- Discord — full bot support across servers, channels, and DMs.
- Signal — privacy-focused, via signal-cli.
- iMessage — available on macOS via BlueBubbles integration.
- Slack — workspace apps via the Bolt SDK.
And the list goes well beyond the big six — Matrix, IRC, Mattermost, Microsoft Teams, Nextcloud Talk, and more are available via plugins.
You can run multiple channels simultaneously from a single Gateway. Send a message from Telegram, get a reply. Then DM yourself on Discord, get the same agent picking up the conversation. One installation, every platform.
> Pro tip: Telegram is usually the easiest place to start. It takes about two minutes to create a bot token and you’re up and running.
Skills: Extend Your AI With New Superpowers
Out of the box, OpenClaw gives you a capable AI assistant. But the magic really starts when you add Skills.
What Is an AgentSkill?
An AgentSkill is a self-contained capability package — a set of tools, prompts, and instructions that get loaded into your AI’s context when relevant. Skills are how your assistant learns to do specific jobs: pull live data, control software, talk to APIs, or automate workflows.
The ClawHub Marketplace
Skills are distributed through ClawHub, an open skill marketplace. Installing a skill is a single command:
clawhub install weatherOr search for what you need:
clawhub search "smart home"Skills Worth Installing
Here’s a taste of what’s available right now:
| Skill | What It Does |
|---|---|
| weather | Current conditions and forecasts via wttr.in / Open-Meteo. No API key needed. |
| github | Check PR status, CI runs, create issues, review code — all from chat. |
| whisper | Local speech-to-text transcription using OpenAI’s Whisper model. |
| tmux | Remote-control terminal sessions by sending keystrokes from chat. |
| openhue | Smart home control for Philips Hue lights. |
| obsidian | Read and write notes in your Obsidian vault. |
| camsnap | Grab a snapshot from a connected camera. |
| sag | Text-to-speech via ElevenLabs — send voice replies. |
| trello | Manage cards and boards from chat. |
| gemini | One-shot Q&A and generation with the Gemini CLI. |
And there are dozens more in the marketplace: Notion, Spotify, Discord bots, image generation (nano-banana-pro), web search via Brave/Perplexity, and a growing community of developer-contributed skills.
Because skills are just directories of Markdown files and scripts, writing your own is within reach for any developer. The spec is documented and the community is active.
Why Self-Hosted Actually Matters
“Self-hosted” can sound like a buzzword, but for developers, the practical benefits are concrete.
Privacy You Can Verify
When your OpenClaw Gateway runs on your hardware, your conversations stay on your hardware. There’s no external service ingesting your queries to train future models. There’s no Terms of Service that changes overnight to permit things you didn’t agree to. If you’re working on proprietary code or sensitive projects, this matters more than you might think.
Cost That Makes Sense
You bring your own API keys — Anthropic, OpenAI, or any supported provider. You pay for what you use, at API rates, with no platform markup. For moderate usage, this is dramatically cheaper than premium subscriptions. For heavy users, the savings compound fast.
Customisation Without Limits
Because you run the whole stack, you can configure things that hosted products won’t let you touch: custom system prompts, multi-agent routing rules, per-channel access controls, allowlists, skill composition, model failover chains. OpenClaw’s config file (~/.openclaw/openclaw.json) gives you fine-grained control over every aspect of behaviour.
Who Is OpenClaw For?
OpenClaw is a great fit for:
- Developers who want a personal AI agent that understands their workflow (GitHub, terminal, editor) without sending their code to third-party servers.
- Privacy-conscious users who want the power of modern AI without the data trade-off.
- Power users who’ve hit the ceiling on what hosted platforms allow — custom integrations, unusual channels, complex automation.
- Hobbyists running home servers or a Raspberry Pi who want an always-on assistant for ~$0/month in infrastructure.
- Teams who want to self-host an AI tool on internal infrastructure without routing sensitive data through external SaaS.
If you’re comfortable with a terminal and you’ve used npm before, you’re already qualified to run OpenClaw.
Getting Started in 5 Minutes
Here’s the short version. Start by installing:
# Recommended: the installer script (handles Node detection automatically)
curl -fsSL https://openclaw.ai/install.sh | bash
# Or via npm if you already manage Node yourself
npm install -g openclaw@latestThen run the onboarding wizard, which walks you through auth, Gateway settings, and channel connection:
openclaw onboard --install-daemonThe --install-daemon flag sets up OpenClaw as a background service so it survives reboots. Once onboarding is done, check your status:
openclaw gateway status
openclaw dashboard # opens the browser Control UIFrom there, connect a channel (Telegram takes under two minutes), send your first message, and you’re live.
> Note: You’ll need Node.js 22 LTS (v22.16+) or Node 24. The installer script will handle this if you don’t have it.
Frequently Asked Questions
Do I need to pay for OpenClaw itself? No. OpenClaw is MIT-licensed and free to use. You pay only for your own API keys (e.g., Anthropic or OpenAI). Usage costs depend on how much you chat — for moderate use, it’s typically a few dollars a month.
Can it run 24/7 without my laptop being on? Yes — that’s the sweet spot. Run it on a VPS (Hostinger is a popular affordable option starting under $5/month) or a Raspberry Pi (available on Amazon). The Gateway runs as a systemd service and auto-starts on boot.
Is my data stored anywhere? OpenClaw itself does not store your data externally. Your conversations are local to the machine running the Gateway. The AI responses are processed by whichever model provider you configure — so review that provider’s data policy (Anthropic, OpenAI, etc.) as you would for any API call.
What AI models does it support? OpenClaw supports any provider that works with the built-in model catalog, including Anthropic (Claude), OpenAI (GPT), Google (Gemini), Amazon Bedrock, and more. You can also configure failover chains — if your primary model hits a rate limit, it automatically falls back to the next in the list.
