Hosted headless-browser fleet for agents, metered in browser-hours, with live view, session replay, and CAPTCHA solving plus stealth on paid plans.
Teams that already have an agent and need someone else to run the browsers: Browserbase sells isolated Chromium sessions with live view, session replay and step logs, which is what you need to see why a run failed. The quickstart documents Playwright (JS, Python, Java, C#), Puppeteer (JS), Selenium (JS, Python, Java, C#, Ruby) and Stagehand, so existing Playwright or Selenium code connects without a rewrite. Session region is selectable per session across four AWS regions, which matters if you have a data-location requirement.
Do not prototype anti-bot work on the free plan: the pricing page lists no CAPTCHA solving and no stealth mode on Free, a 15-minute session cap and 1 browser hour. The strongest evasion tier, Verified Agents plus advanced stealth, is Scale-only, and the stealth docs say you must email hello@browserbase.com to trial Verified, so there is no self-serve path to it. Budgeting is also not one number: browser-hours, Search calls, Fetch calls, proxy GB and Model Gateway tokens are metered separately and stack on the same invoice.
Pros
Cons
Five meters run in parallel. Browser time is charged per browser-hour with published overage of $0.12 on Developer and $0.10 on Startup. Search calls, Fetch calls, proxy bandwidth per GB and Model Gateway tokens are each billed separately. A single agent run can therefore touch four line items at once, so forecast each meter rather than assuming the monthly plan fee is the cost.
On paid plans, yes. The pricing page lists auto CAPTCHA solving and basic stealth mode on Developer and Startup, and Verified Agents plus advanced stealth on Scale. Free lists neither. The stealth docs describe Verified sessions as a purpose-built Chromium with real fingerprints that defaults to Windows, and hedge the outcome: Verified only 'can provide' higher success rates, with no guaranteed figure.
Yes. The create-a-session API reference documents a region parameter accepting us-west-2 as default, plus us-east-1, eu-central-1 and ap-southeast-1, so EU or Singapore execution is a per-session choice. Session timeout is configurable from 60 seconds to 21,600 seconds, a six-hour ceiling. Recorded session data is retained for 7 days on Free and 30 days on Developer and Startup.
No. Across the pricing page, docs introduction and stealth-mode documentation there is no task success rate, WebVoyager score or anti-bot bypass percentage. The reliability story is observability instead of a score: live view, session replays and per-step logs let you detect and diagnose failures yourself. If you need a number before committing, you have to run your own evaluation on your target sites.
