Use tool ↗About Browserbase
Browserbase runs headless browsers in the cloud and rents that capacity to developers building agents that need to act inside a real browser: filling forms, logging into accounts and reading sites that have no API. Around the browsers it sells the pieces that are painful to build in-house — proxies, automatic CAPTCHA solving on paid plans, an Agent Identity layer for anti-bot and authentication walls, live view, logs and session replay — plus a Search API and a Fetch API that turn the web into agent context, and a Model Gateway for calling models through one key. The company maintains Stagehand, its open-source SDK for browser agents, names Ramp, Microsoft and Lovable among customers and reports 35 million-plus sessions a month. Browserbase Inc. is in San Francisco, was founded in early 2024 and raised a $40 million Series B led by Notable Capital in June 2025.

Pros & cons of Browserbase
Browserbase removes the operational work of running headless Chrome at scale - proxies, fingerprinting, CAPTCHA, session storage - which is exactly the layer most agent-building teams don't want to own themselves. It's infrastructure, not a finished agent, so there's still integration work to do on top of it.
Pros
- Automatic CAPTCHA solving and proxy/fingerprint handling out of the box
- Free tier available to test before paying
- Session replay and observability for debugging agent runs
- Open-source Stagehand framework for the automation layer
Cons
- Free tier is capped at just 1 browser hour, not enough for real workloads
- Requires developer effort to wire into an actual agent - it's infrastructure, not an end-user tool
- Overage billing on browser-hours can add up for high-volume use
Best for
- Developers building browser-using AI agents
- Teams scraping sites that block plain HTTP requests
- Products that need agents to log in and act on behalf of users
Not for
- Non-technical users looking for a ready-made agent product
- Simple scraping jobs a basic HTTP client could already handle
Watch out: The free plan's 1,000 search/fetch calls and 1-hour browser budget are meant for evaluation, not production traffic - most real usage lands on the $20+/month tiers.
