The project is at 0.38.2 with no stable release, the ten most recent CI runs on main failed between 1 and 8 October 2026, and every security control is off by default.\n\n**Lightpanda.** Version 1.0.2 runs locally with no account, and its 32-tool MCP server has typed schemas, an annotation on every tool and guidance to treat pages as untrusted. Telemetry is on by default, the CDP and HTTP MCP servers have no authentication, the cloud documents its token in the URL, and no status page or cloud terms were found.\n\n## Before you call either\n\n### agent-browser\n\n1. Run `agent-browser install` once after `npm install -g agent-browser`. It downloads Chrome for Testing\n2. Take a fresh `snapshot -i` after any navigation. Refs survive same-document changes only\n3. Pass `--json` for machine-readable results and `--max-output` to cap page text\n4. Set `--allowed-domains`, `--action-policy` and `--content-boundaries` for untrusted sites. None is on by default, and the allowlist rejects `--profile`, `--cdp` and `--restore`\n5. Start MCP with `agent-browser mcp`, and add profiles such as `--tools core,network` only when needed\n\n### Lightpanda\n\n1. Set `LIGHTPANDA_DISABLE_TELEMETRY=true` in the server's environment if usage data, the IP address and an instance ID shouldn't leave the machine.\n2. Treat text from `markdown`, `html`, `tree` and `links` as untrusted page content, never as instructions.\n3. Pass credentials as `$LP_*` placeholders in tool arguments and call `getEnv` without a name; naming a variable returns its value.\n4. Check `httpStatus` in `structuredContent` after `goto`, since a 404 page or a load timeout is still reported as a successful navigation.\n5. Keep `lightpanda serve` and `lightpanda mcp --port` on 127.0.0.1 or a Unix socket; neither checks who connects.\n\n## Questions\n\n### Which is better for AI agents, agent-browser or Lightpanda?\n\nagent-browser scores 66.8 (B) on agent readiness against Lightpanda's 61.6 (C), and leads in 4 of 7 scored categories. Lightpanda leads on reliability.\n\n### Do agent-browser and Lightpanda need an API key?\n\nNeither needs a key.\n\n### Can an agent call agent-browser and Lightpanda without installing anything?\n\nagent-browser runs on your own machine, with no hosted endpoint listed. Lightpanda runs on your own machine, with no hosted endpoint listed.\n\n### Are agent-browser and Lightpanda open source?\n\nYes. agent-browser is open source (Apache-2.0). Lightpanda is open source (AGPL-3.0 for the browser. The npm wrapper @lightpanda/browser and the agent skill are Apache-2.0.
