About
ClawLess is a serverless runtime that lets you run OpenClaw agents entirely in the browser — no backend server, no cloud account, no containers. It uses WebAssembly to provide a full Node.js environment client-side, with access to the entire npm ecosystem (3.4M+ packages). A YAML-based policy engine controls what the agent can access (files, processes, ports, network egress), and all actions are audit-logged. It's open source under MIT and available as the clawcontainer npm package.
Developers who want to build and demo OpenClaw agents without spinning up any server infrastructure. Also well-suited for CI/CD pipelines, educational environments, or scenarios where keeping computation client-side is a privacy or compliance requirement.
Pros & Cons
Pros
- check Zero infrastructure: runs entirely in-browser with no server setup whatsoever
- check Full npm package access via WASM means agents can use real dependencies, not a sandboxed subset
- check Declarative YAML policies make security controls explicit and reviewable without writing code
- check Audit logging built in — you can see exactly what the agent did and why
- check MIT licensed and free — no usage costs beyond AI provider API calls
Cons
- close Browser-based execution has real performance limits — intensive tasks will be constrained by browser resources
- close WASM Node.js is not identical to native Node.js; some packages with native bindings won't work
- close Persistent state between sessions requires extra plumbing (no built-in storage)
- close Primarily targets developers — not a no-code tool
