What is OpenClaw? A Beginner's Guide

OpenClaw is an open-source AI agent platform that gives language models access to a real computer — with a filesystem, terminal, web browser, Git, and a suite of external integrations. It's the difference between an AI that talks about writing code and an AI that actually writes, runs, and debugs it.

Unlike chat interfaces, OpenClaw agents maintain persistent memory across sessions. They remember your preferences, your codebase, your architecture decisions, and your ongoing projects. Every conversation picks up where the last one left off.

What Makes OpenClaw Different

Most AI tools are stateless chat interfaces. You get a response, the context evaporates, and tomorrow you start from scratch. OpenClaw is built around a fundamentally different model:

• Persistent workspace. Your agent's files, memory, and context live on a dedicated volume at /home/node/.openclaw. Reboots don't erase memory.
• Real tool execution. Web search, shell commands, file reads and writes, Git operations, Linear issues, email via Resend — your agent can act, not just advise.
• Multi-model routing. OpenClaw supports pluggable model providers. Switch between Gemini, Claude, GPT-4, or any OpenAI-compatible model without reconfiguring your workflow.
• Web interface. The gateway exposes a terminal UI on port 18790, accessible from any browser via a WebSocket connection. No SSH, no local install required.
• Open source. The entire platform is open source. No model lock-in, no vendor dependency on the agent runtime itself.

What Can You Do With It?

The tool profile determines what capabilities the agent has access to. In full mode — the default for Komodo agents — every tool category is enabled:

• Coding assistant — reads, writes, and runs code with full project context across sessions
• Research agent — browses the web, summarizes findings, tracks topics over time
• DevOps agent — monitors deployments, manages cloud resources, executes scripts
• Automation engine — runs heartbeat tasks on a schedule, processes queues, sends alerts
• Team member — receives messages via NATS, posts updates to team channels, escalates blockers

How It Works Under the Hood

The Gateway Architecture

OpenClaw's core is a gateway process that starts on port 18790. It serves a WebSocket-based terminal UI and acts as the broker between the user interface and the underlying AI model calls. When you open your agent's URL, your browser establishes a WebSocket connection to the gateway, and the gateway manages the conversation loop with the configured model provider.

The gateway config lives in openclaw.json — a JSON file that specifies everything about how the agent behaves: which models to use, which tools to enable, the heartbeat schedule, and gateway security settings.

The openclaw.json Config Schema

A typical Komodo agent's openclaw.json looks like this (simplified):

{
  "scope": "agent",
  "gateway": {
    "port": 18790,
    "token": "<GATEWAY_TOKEN>"
  },
  "agents": {
    "defaults": {
      "model": {
        "primary": "cloudflare-gemini/gemini-3.1-flash-lite-preview",
        "fallbacks": [
          "cloudflare-gemini/gemini-2.5-flash",
          "cloudflare-anthropic/claude-sonnet-4-20250514"
        ]
      },
      "heartbeat": {
        "every": "10m",
        "prompt": "Read HEARTBEAT.md and follow it.",
        "activeHours": {
          "start": "06:00",
          "end": "22:00",
          "timezone": "America/New_York"
        }
      },
      "elevatedDefault": "full"
    }
  },
  "tools": {
    "profile": "full",
    "exec": { "security": "full", "ask": "off" }
  }
}

The tools.exec.ask = "off" flag is particularly significant: it means the agent executes shell commands without asking for confirmation. This is what enables truly autonomous operation — an agent that can run scripts, install packages, and manage files without waiting for human approval on each step.

Multi-Model Provider System

Model providers are defined under the models.providers key. Komodo agents use two providers by default:

• cloudflare-gemini — routes to Google's Gemini models via the Cloudflare AI Gateway (komodoagents-public) at the /google-ai-studio/v1beta endpoint
• cloudflare-anthropic — routes to Anthropic's Claude models through the same gateway at the /anthropic endpoint

The primary model is gemini-3.1-flash-lite-preview — fast and cost-efficient for routine tasks. If it's unavailable, the gateway automatically falls back to gemini-2.5-flash, then to claude-sonnet-4-20250514 for complex reasoning. You never lose an agent to a model outage.

Persistent Volume Storage

An agent's data lives at /home/node/.openclaw — a persistent volume that survives reboots, image updates, and even machine replacements. This directory contains:

• openclaw.json — the gateway configuration
• workspace/ — markdown context files (IDENTITY.md, COMPANY.md, HEARTBEAT.md, TOOLS.md)
• soul/ — the four-layer soul config JSON files downloaded at boot
• Conversation history and any files the agent creates during its work

The workspace markdown files are loaded as context at the start of every conversation. This is how an agent "remembers" who it is, what company it works for, and what it's supposed to be doing — without any database query or external API call.

Heartbeat Scheduling

OpenClaw supports a heartbeat system: a configurable interval (default: every 10 minutes during active hours 06:00–22:00 ET) where the agent wakes up, reads its HEARTBEAT.md file, and acts on whatever instructions are there. This is how an unattended agent monitors deployments, checks task queues, sends reports, or escalates blockers — without any human prompt.

How to Get Started

You have two paths:

Self-host: Install OpenClaw on a Linux machine or Mac. You'll need Node.js 20, configure openclaw.json manually, and manage updates yourself. Good for experimentation.

Managed hosting: Sign up at Komodo Agents. Your agent provisions in under 60 seconds — with a dedicated VM, pre-configured model fallback chain, vault-backed secrets, NATS messaging, and the full tool profile active from day one. See our OpenClaw hosting guide to compare your options.
