What AI browser agents do
AI browser agents use a language model to operate a web browser: they read pages, click, type and submit forms to finish a task or extract data. They are built for sites with no API, and most are sold to developers or operations teams rather than as consumer apps. Some products are the agent itself, others only supply the cloud browsers agents run on.
Who uses them: Developers building web agents, Operations and back-office teams automating forms and downloads, QA and testing teams, Data and lead-generation teams, Companies automating legacy portals with no API.
What to check before you buy
Agent or infrastructure. Browserbase sells browsers, Browser Use and Skyvern sell agents; pick based on whether you already have an agent.
Pricing model and real cost. Monthly credits (Skyvern), hours plus overages (Browserbase) and pure pay-as-you-go with a 20 percent model fee (Browser Use) behave very differently; a roundup warns proxy, browser-hour and CAPTCHA overages often exceed the advertised price.
. Browser Use is MIT; Skyvern core is AGPL-3.0; licence and self-host option affect cost and control.
Logins, 2FA and credential handling. Who holds credentials and whether they are vaulted decides risk; Skyvern lists 2FA and a vault, mostly on Pro.
Bot protection and CAPTCHA. Stealth, proxies and CAPTCHA solving are often gated to higher plans (Browserbase Free excludes them).
How we test AI browser agents
The test for this category: Same 10 web tasks (book a demo form, collect prices from 5 sites, fill a job application); success out of 20 runs each.
Every tool builds the same three workflows (for example: answer support questions from a help centre, qualify a lead and book a call, pull data from a website into a sheet). Each workflow is run 20 times with the same inputs.
Each tool is tested on a paid plan, and its review shows the plan, the price and the test dates. The overall score is the average of the five parts on the right, rounded to the nearest half star. See the full method for AI agents and automation tools.
What we measure
- Runs completed correctly out of 20
- Time to build each workflow from sign-up
- How failures are handled (retries, alerts, human hand-off)
- Cost per 100 runs at list prices
- Integrations available for the workflow without code

If there's a strange new AI tool making its way around the internet, I've probably already bookmarked it. My favorite part is figuring out what these platforms can actually do.
