It has no MCP server of its own, Selenium Manager sends usage statistics by default, and Grid accepts unauthenticated sessions unless a username and password are set.\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### Selenium\n\n1. Install with `pip install selenium` (Python 3.10 or later) and let Selenium Manager fetch drivers. Do not set driver paths\n2. Use `WebDriverWait` with expected conditions, never fixed sleeps, and do not mix implicit and explicit waits\n3. Set `SE_AVOID_STATS=true` to stop Selenium Manager sending usage statistics\n4. Point coding agents at https://www.selenium.dev/llms.txt. Most Selenium 2 and 3 era examples use removed APIs\n5. Set `--username` and `--password` before exposing a Grid beyond localhost. Check `http://localhost:4444/status` before creating sessions\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, Selenium or TinyFish?\n\nSelenium scores 73.6 (BB) on agent readiness against TinyFish's 67.7 (B), and leads in 5 of 7 scored categories. TinyFish leads on agent ergonomics and security \u0026 auth.\n\n### Can an agent call Selenium and TinyFish without installing anything?\n\nNo hosted endpoint is listed for Selenium. TinyFish has a hosted endpoint at https://agent.tinyfish.ai.\n\n### Are Selenium and TinyFish open source?\n\nSelenium 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/selenium-vs-tinyfish.json, and with the fewest tokens: https://www.anchorterminal.com/compare/selenium-vs-tinyfish.min.md\n- Over MCP at https://www.anchorterminal.com/mcp (no key): `compare_tools {\"a\": \"selenium\", \"b\": \"tinyfish\"}`.
