Anchor

At a glance

Anchor Browser is worth evaluating when an agent needs to work through a website that has no suitable API and you do not want to operate the browser fleet yourself. It provides cloud browser sessions, natural-language tasks and reusable automation tasks, with options for persistent authenticated identities. The useful tradeoff is less browser infrastructure to run in exchange for usage charges and entrusting a service with the pages and accounts involved.

Good fit

Builders connecting an agent to web interfaces, especially workflows that need a saved login across sessions. A browser session can be driven through a remote browser connection or Anchor’s API, while a natural-language task delegates the interaction to an agent. Reusable Automation Tasks are a separate workflow product. Managed identities can preserve cookies and other browser state, with credentials available for re-login where configured. A saved profile alone lasts only as long as the target site accepts its session.

Consider something else when

A direct API already covers the job, you need only a small local browser script, or the target data cannot be processed in a cloud browser under an acceptable agreement. Persistent login is not permission to let an agent make unrestricted changes. Choose the accounts and actions deliberately. The inspected documentation’s natural-language endpoint does not honor an Idempotency-Key: repeating a request starts another task, which matters for retries around consequential actions.

Start here

The documented first task extracts a heading from example.com. Use that kind of public, read-only target to check the returned result, task cost and session lifecycle before connecting an account. The linked playground currently redirected to sign-in in this assessment, despite the introduction describing a playground without an API key. No account was created or task submitted. For API use, obtain a key through the official dashboard and follow the current SDK quickstart; end trial sessions when finished.

Cost and requirements

Checked October 31, 2026: the site advertises five free monthly credits and Starter at $50 per month. The detailed pricing matters more than the headline: reusable task runs cost the higher of a $0.10 task fee or their infrastructure cost; failed runs still incur infrastructure charges. Perform Web Task instead bills AI steps plus infrastructure. Published rates include $0.01 per browser creation, $0.05 per browser hour, proxy traffic and $0.01 to $0.10 per AI step. A bring-your-own model key still incurs Anchor’s step charge as well as provider usage.

Limits to know

No cloud session, authenticated identity or agent task was run here. Marketing speed, reliability and benchmark numbers were not independently verified. Identity documentation explicitly includes sensitive credentials and browser profiles; the general privacy policy is not a substitute for confirming your service’s data terms. The pricing docs list seven-day retention for Free and Starter, while other plans offer different settings. Confirm what that retention covers, recording behavior, deletion and model-provider handling before using sensitive data. Browser access through this service also does not override a target site’s rules.

Still unclear

• What end-to-end success rate and total cost does the intended workflow achieve, including retries?
• Which session, recording, identity and model data are retained under the selected plan and agreement?
