What is OpenClaw? The Complete Guide

Everything you need to know about the open-source AI assistant platform that has taken the developer world by storm — from beginner-friendly explanations to deep technical architecture.

What is OpenClaw?

OpenClaw is a free, open-source personal AI assistant platform. Created by Peter Steinberger, it has earned 335K+ stars on GitHub. That makes it one of the most popular open-source projects in existence. The current release is v2026.3.8, and its mascot is a lobster.

Unlike ChatGPT or Claude.ai, OpenClaw runs on YOUR server. You own every byte of data it processes. You choose which AI model powers it. You decide which messaging channels it connects to. There are no vendor lock-ins, no monthly subscriptions to an AI provider's platform, and no third-party data harvesting.

Think of it as having a brilliant personal assistant who never sleeps, remembers everything you tell it, and works across all your messaging apps simultaneously. Send it a message on WhatsApp asking to schedule a meeting. Follow up on Telegram with additional context. Check in on Discord later. OpenClaw remembers the entire conversation thread across every channel.

It connects to WhatsApp, Telegram, Discord, Slack, Signal, and iMessage. It integrates with 191+ external services. It can automate tasks, monitor data feeds, generate images, search the web, manage files, and chain complex workflows together. And every line of its source code is available for you to inspect, modify, and improve.

History

OpenClaw did not appear overnight. It went through three major identities before becoming the project developers know today. Here is the timeline.

Early 2024

Clawdbot

Peter Steinberger released the first prototype under the name Clawdbot. It was a simple bridge connecting Claude to Telegram. The codebase was scrappy — a single Node.js script under 500 lines. It supported one AI model, one messaging channel, and had no memory between conversations. But it worked, and developers noticed.

Mid 2024

Moltbot

As the project gained traction, Steinberger renamed it to Moltbot (a nod to molting, the process lobsters use to grow). This version introduced multi-model support, letting users switch between Claude and GPT. It added a plugin system and basic conversation persistence. The GitHub repository crossed 50K stars.

Late 2024 – Present

OpenClaw

The final rename to OpenClaw reflected the project's maturity and open-source identity. This version introduced the 6-layer Supermemory system, multi-channel messaging, ClawHub (the skills marketplace), and the Gateway architecture. The project went viral, crossing 335K+ GitHub stars and becoming one of the most starred repositories on the platform. Version v2026.3.8 is the latest stable release.

The lobster mascot has been with the project since day one. Lobsters grow by molting — shedding their old shell to make room for a bigger one. The metaphor fits an AI assistant that continuously learns and adapts to its user.

How It Works

OpenClaw uses a Gateway architecture. Every message flows through a single processing pipeline, regardless of which channel it arrives from or which AI model generates the response. Here is the flow, step by step.

1

Message arrives

You send a message on WhatsApp, Telegram, Discord, Slack, Signal, or iMessage.

2

Gateway receives it

The Gateway normalizes the message into a standard format, regardless of the source channel.

3

Context assembly

The Gateway pulls relevant memories, conversation history, and user preferences from the Supermemory system.

4

AI model processes

The assembled prompt (your message + context) goes to your chosen AI model — Claude, GPT, Gemini, or a local model.

5

Response routing

The AI generates a response. The Gateway formats it for the original channel and sends it back.

Think of the Gateway as a receptionist who speaks every language. It receives your messages from any channel, translates them for the AI, and sends back the response in the format each channel expects. WhatsApp needs different formatting than Discord. Telegram supports different media types than Slack. The Gateway handles all of these differences transparently.

Everything runs on your VPS. Your messages never pass through OpenClaw's servers because there are no OpenClaw servers. The only external communication is between your server and the AI model provider's API (Anthropic, OpenAI, Google, etc.). If you run a local model through Ollama, even that call stays on your machine.

The Gateway pattern means adding a new messaging channel does not require changes to the AI logic. Similarly, switching AI models does not require changes to your channel configuration. Each layer is independent.

Key Features

OpenClaw packs more functionality into a self-hosted package than most commercial AI assistants offer. Here are the features that set it apart.

Multi-Model

Switch between Claude Opus 4.6, GPT-5, Gemini 3 Pro, DeepSeek V3, Mistral Large, Llama 4, and more. Change models with a single configuration line. No code changes needed.

Multi-Channel

Run WhatsApp, Telegram, Discord, Slack, Signal, and iMessage simultaneously. One AI brain, six inboxes. Conversations sync across channels automatically.

Persistent Memory

The 6-layer Supermemory system achieves 85.9% recall accuracy, compared to 58.3% with classic context-window approaches. It remembers your preferences, past conversations, and personal facts across sessions.

191+ Integrations

Connect to GitHub, Notion, Binance, Spotify, Home Assistant, Google Calendar, Linear, Jira, and dozens more. Automate workflows that span multiple services.

Skills & ClawHub

Extend functionality with community-built skills from ClawHub. Web search, image generation, code execution, file management, and calendar sync are just the starting point.

Self-Hosted

Your server, your data, your rules. No telemetry, no data sharing, no third-party access. Run it on a $5 VPS or a dedicated server in your basement.

Automation

Schedule recurring tasks, react to events from connected services, and chain multi-step actions. Set up a morning briefing, auto-respond to emails, or monitor crypto prices.

Open Source

MIT license, free forever, transparent code. 335K+ GitHub stars and growing. Inspect every line, contribute upstream, or fork it for your own needs.

Compatible AI Models

OpenClaw supports every major AI model available as of March 2026. You can switch models at any time without reinstalling or reconfiguring your channels. Here is the full compatibility table.

Costs listed are approximate per message. With prompt caching enabled, costs drop by roughly 60%. For most personal use, expect to spend $2 to $15 per month on API calls. Start with Haiku 4.5 or Gemini 3 Flash while testing, then switch to a more capable model once everything is configured.

Many users run a hybrid setup. They route simple questions to Haiku 4.5 (fast, cheap) and escalate complex requests to Opus 4.6 or GPT-5 (slower, smarter). OpenClaw supports model routing rules that make this automatic based on message complexity, channel, or time of day.

Messaging Channels

OpenClaw connects to six messaging platforms. Each has different setup requirements, different strengths, and different audiences. You can run all six simultaneously from a single instance.

WhatsAppMost Popular

The most requested channel. Works with Meta's Business API or open-source bridges like Baileys. Supports text, images, voice messages, and documents.

Setup difficulty: Moderate — requires a Meta Business account

TelegramEasiest

The easiest channel to set up. Create a bot through BotFather, paste the token, and you are live. Supports rich formatting, inline keyboards, file sharing, and group conversations.

Setup difficulty: Easy — 5 minutes with BotFather

Discord

Ideal for teams and communities. Your AI assistant lives in a Discord server, responds to mentions or DMs, and can manage channels. Great for developer teams who already live in Discord.

Setup difficulty: Easy — create a bot in Discord Developer Portal

Slack

Built for the workplace. Deploy your AI assistant as a Slack app that responds in channels and threads. Pairs well with integrations like Jira, Linear, and Google Workspace for workflow automation.

Setup difficulty: Moderate — requires Slack App configuration

Signal

The privacy-focused option. Signal's end-to-end encryption combined with OpenClaw's self-hosted architecture creates one of the most private AI assistant setups possible. Uses the signal-cli bridge.

Setup difficulty: Hard — requires signal-cli and phone number registration

iMessage

For users deep in the Apple ecosystem. Requires a Mac running as a bridge server (or a macOS VM). Once configured, your AI assistant appears as a regular iMessage contact.

Setup difficulty: Hard — requires a Mac or macOS instance as bridge

Skills & ClawHub

Skills are plugins that extend what OpenClaw can do. Each skill adds a specific capability — web search, image generation, code execution, file management, calendar sync, or anything else a developer can build. Skills are written in JavaScript or TypeScript and follow a standard interface.

ClawHub is the community marketplace where developers publish and share skills. Think of it like npm for AI assistant capabilities. Browse available skills, install them with a single command, and your OpenClaw instance gains new abilities instantly.

OpenClawPro audits every skill before installing it on client servers.

Security Overview

OpenClaw is powerful software that runs with access to your AI API keys, messaging accounts, and personal data. That power becomes a liability when security is neglected. And the data shows that most users neglect it.

42,665
Instances exposed on the internet
93.4%
Without authentication
341
Malicious skills detected

The ClawHavoc vulnerability (CVE-2026-25253) demonstrated how an exposed instance could be hijacked to exfiltrate API keys, read private conversations, and execute arbitrary code on the host server. Attackers actively scan for unprotected OpenClaw instances using tools like Shodan and Censys.

The fix is straightforward. Enable authentication, configure a firewall, use a reverse proxy with SSL, and keep your installation updated. Most exploits target instances that skip these basic steps.

Real Costs

OpenClaw itself is free. But running it requires a server and AI API access. Here is an honest breakdown of what you will actually pay each month.

ExpenseMonthly CostNotes
VPS Hosting$5 – $24/moHetzner CX22 at $4.50, DigitalOcean at $6, or premium at $24
AI API Usage$2 – $30/moDepends on model choice and message volume (see model table above)
OpenClaw Software$0 (free)MIT license, free forever
Domain Name$0 – $1/moOptional. ~$10/year for a .com domain
Typical Total$10 – $50/moVaries by model and usage

Compare that to ChatGPT Plus at $20/month. With ChatGPT, you get one model (GPT-5), one web interface, no messaging channel integration, no persistent memory across sessions, no automation, and no data ownership. With OpenClaw at a similar price point, you get all of the above and more.

The cheapest viable setup uses a $5 Hetzner VPS with Haiku 4.5 ($0.001 per message). At 100 messages per day, that comes to roughly $8 per month total. The most capable setup uses a $24 premium VPS with Claude Opus 4.6, costing $30 to $50 per month depending on usage.

Who Uses OpenClaw

OpenClaw attracts users from across the technical spectrum. Here are the four most common profiles and how they use the platform.
