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**Hyperbrowser.** Sessions, Fetch and Search can be bought by x402 at api.hyperbrowser.ai with USDC on Base or Solana and no account, and unit prices are public. The official MCP server was last published in April 2025, no request rate limits or SLA are published, and the privacy notice covers only the website.\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### Hyperbrowser\n\n1. With a wallet and no key, POST to https://api.hyperbrowser.ai/x402/session and read the `PAYMENT-REQUIRED` header. Sessions are prepaid for 5 to 60 minutes with no refund\n2. Save the x402 creation response. It holds the only copy of the connection tokens, and `managementToken` is what stops the session\n3. Stop sessions explicitly in cleanup code. Browser time bills per second until the timeout\n4. Use Fetch at $0.001 a page for static pages and keep browser sessions for pages that need interaction\n5. Add `\u0026keepAlive=true` to `wsEndpoint` to reconnect after a CDP disconnect. Treat that URL as a secret because it carries the session token\n\n## Questions\n\n### Which is better for AI agents, agent-browser or Hyperbrowser?\n\nHyperbrowser and agent-browser score within a point of each other on agent readiness, 66.9 (B) and 66.6 (B). agent-browser leads on schema \u0026 documentation, agent ergonomics and security \u0026 auth.\n\n### Do agent-browser and Hyperbrowser need an API key?\n\nagent-browser needs no key. Hyperbrowser takes an API key or an OAuth sign-in. An agent can also pay Hyperbrowser per call over x402, with no account.\n\n### Can an agent call agent-browser and Hyperbrowser without installing anything?\n\nagent-browser runs on your own machine, with no hosted endpoint listed. Hyperbrowser has a hosted endpoint at https://api.hyperbrowser.ai.\n\n### Are agent-browser and Hyperbrowser open source?\n\nagent-browser is open source (Apache-2.0). No open-source release is listed for Hyperbrowser.\n\n\n## For agents\n\n- This comparison as JSON: https://www.anchorterminal.com/compare/agent-browser-vs-hyperbrowser.json, and with the fewest tokens: https://www.anchorterminal.com/compare/agent-browser-vs-hyperbrowser.min.md\n- Over MCP at https://www.anchorterminal.com/mcp (no key): `compare_tools {\"a\": \"agent-browser\", \"b\": \"hyperbrowser\"}`.
