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**TinyFish.** OpenAPI documents are published for five APIs, errors carry typed codes and request IDs, and Search and Fetch are free within daily allowances. The terms let Tiny Fish train its models on customer data, run creation takes no idempotency keys, and the status page shows an hour or more of downtime on several days for the Browser and Search APIs.\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### TinyFish\n\n1. Check `result` as well as `status`. A run can be `COMPLETED` while the goal failed, with `result.status` set to `failure`\n2. Don't retry `POST /v1/automation/run` blindly after a timeout. There are no idempotency keys, so list runs first to avoid duplicates\n3. Use `/v1/automation/run-async` or `/run-sse` when a run may need cancelling. Runs started with the synchronous endpoint can't be cancelled\n4. Allow 60 seconds for Browser session creation, connect Playwright to `cdp_url` (not `base_url`), and `DELETE` the session when done because billing is per minute\n5. Never put passwords in `goal`, which is logged. Pass `use_vault: true` with `credential_item_ids`, or `use_profile: true` for saved login state\n\n## Questions\n\n### Which is better for AI agents, agent-browser or TinyFish?\n\nTinyFish scores 67.7 (B) on agent readiness against agent-browser's 66.6 (B), and leads in 4 of 7 scored categories. agent-browser leads on security \u0026 auth and payments \u0026 pricing.\n\n### Do agent-browser and TinyFish need an API key?\n\nagent-browser needs no key. TinyFish takes an API key or an OAuth sign-in.\n\n### Can an agent call agent-browser and TinyFish without installing anything?\n\nagent-browser runs on your own machine, with no hosted endpoint listed. TinyFish has a hosted endpoint at https://agent.tinyfish.ai.\n\n### Are agent-browser and TinyFish open source?\n\nagent-browser is open source (Apache-2.0). No open-source release is listed for TinyFish.\n\n\n## For agents\n\n- This comparison as JSON: https://www.anchorterminal.com/compare/agent-browser-vs-tinyfish.json, and with the fewest tokens: https://www.anchorterminal.com/compare/agent-browser-vs-tinyfish.min.md\n- Over MCP at https://www.anchorterminal.com/mcp (no key): `compare_tools {\"a\": \"agent-browser\", \"b\": \"tinyfish\"}`.
