Browser Use vs TinyFish

Browser Use scores 77.9 (BB) on agent readiness against TinyFish's 67.7 (B), and leads in 4 of 7 scored categories. Both do browser automation. Browser Use accepts x402. TinyFish doesn't.

Which one, for what

Browser Use BB

Good for An agent that wants to hand a whole browser task to a hosted agent and get a result back, or that needs a low-cost cloud browser over CDP, and for unattended agents that can pay by x402.

Ahead on

  • Reliability, 87 against 60
  • Payments & pricing, 90 against 55
  • Transparency & trust, 65 against 59

Also in its favour

  • Agent-ready, a grade of BB or better
  • An agent can pay per call over x402, with no account
  • Runs on your own machine
  • Open source

Watch for

The privacy policy says inputs are used to train Browser Use's AI models, with no opt-out described outside Enterprise zero data retention

TinyFish B

Good for Agents that want one account for a goal-driven web agent, a raw CDP browser, and free search and fetch.

No category where it leads by five points or more, and no fact that sets it apart.

Watch for

The terms of 17 August 2026 allow Tiny Fish to train and improve its models on customer data. No opt-out was found in the reviewed pages

Verdicts

Browser Use

The hosted cloud accepts x402 top-ups in USDC on Base with no account or API key, and publishes prices, rate limits and three OpenAPI documents. The privacy policy says inputs are used to train Browser Use's models, API keys have no documented scopes, and no prompt-injection guidance was found in the docs.

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.

Before you call either

Browser Use

  1. Send the key as X-Browser-Use-API-Key with no Bearer prefix. A Bearer header returns 401
  2. Stop browsers with PATCH /api/v4/browsers/{id} and {"action":"stop"}. Closing CDP or the SDK client leaves the browser billing
  3. Poll GET /runs/{id}/status, not the full run, and wait for the returned Retry-After on 429, which can be 300 seconds at the edge
  4. Before resubmitting after a timeout, read the existing run's status. The server keeps running and may already have submitted a form
  5. With a wallet and no key, call x402.api.browser-use.com on /api/v2 or /api/v3 routes. A task stops with INSUFFICIENT_CREDITS if credit runs out mid-run

TinyFish

  1. Check result as well as status. A run can be COMPLETED while the goal failed, with result.status set to failure
  2. Don't retry POST /v1/automation/run blindly after a timeout. There are no idempotency keys, so list runs first to avoid duplicates
  3. Use /v1/automation/run-async or /run-sse when a run may need cancelling. Runs started with the synchronous endpoint can't be cancelled
  4. 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
  5. Never put passwords in goal, which is logged. Pass use_vault: true with credential_item_ids, or use_profile: true for saved login state

For companies

Do agents find, use and choose your tools?

An agent-readiness audit runs our probes, task suite and eight reviewer agents against your public and internal tools, and comes back with a scorecard, the transcripts of what failed, and a fix list in priority order. From $2,500, re-run included. We never take payment to move a rank. We do help companies earn one.
