Browserbase

Browserbase runs headless browsers as a service for AI agents and automation, handling concurrency, proxies, CAPTCHA solving, session recording and stealth so teams do not operate their own Chrome fleet. It pairs the hosted infrastructure with Stagehand, an open-source framework that lets an LLM drive a browser instead of hand-written CSS selectors.

Browserbase provides managed headless browser infrastructure for AI agents and web automation, aiming to make the web, in its own framing, as reliable and programmable as an API. Rather than operating a fleet of Chrome instances, customers open a session against Browserbase and get isolation, concurrency, proxy rotation, automatic CAPTCHA solving, live view, session replays and logs as platform features. Each browser runs in a dedicated virtual machine on an isolated subnet behind strict firewalls, a zero-trust design that assumes any given browser may be compromised and is what let the company obtain SOC 2 Type II and HIPAA compliance early. The platform is organised around several primitives: Browsers for raw sessions, managed Agents, Search and Fetch web-data APIs, a sandboxed Runtime for deployments, Identity for authenticated navigation, a unified multi-model API and observability tooling. Two open-source pieces sit alongside it: Stagehand, an automation framework for Python and Node that uses an LLM to interpret a page and act on it — surviving pop-ups, layout changes and form variation that break selector-based scripts — and a Browse CLI. Director, launched with the Series B, lets non-technical users describe a browser task in plain English and generates an executable script deployed on the same infrastructure. Browserbase was founded in 2024 by Paul Klein, a three-time founder whose previous company was acquired by Mux in 2023, and announced a $40 million Series B on 17 June 2025 led by Notable Capital with CRV and Kleiner Perkins participating. At that point it reported more than 1,000 customers, over 20,000 signed-up developers and 50 million browser sessions served in 2025. Named users include Microsoft, Stripe, Vercel, Okta, Anthropic, Perplexity, Ramp, Clay, Amplitude and Lovable.

• ✓
  Managed browser sessions

  Headless Chrome instances on demand with configurable concurrency, so scaling an agent fleet is a plan change rather than an infrastructure project.

• ✓
  Zero-trust isolation

  Every browser runs in a dedicated VM on an isolated subnet behind strict firewalls, preventing lateral movement if a session is compromised.

• ✓
  Stagehand framework

  Open-source Python and Node automation that lets an LLM interpret and act on a page instead of relying on brittle CSS selectors.

• ✓
  Director

  A no-code tool that turns a plain-English description of a browser task into an executable script deployed on Browserbase infrastructure.

• ✓
  Proxies and CAPTCHA solving

  Proxy bandwidth and automatic CAPTCHA solving are bundled into paid plans rather than assembled from separate third-party vendors.

• ✓
  Observability with session replay

  Live view, recorded replays and logs make agent failures debuggable, which is otherwise the hardest part of shipping browser agents.

• ✓
  SOC 2 Type II and HIPAA

  Compliance attestations obtained early, which is what makes the platform usable for finance and healthcare automation.

• •
  Agents operating portals with no API

  Let an agent log into a supplier, insurer or government portal and complete a task no integration exists for.

• •
  Large-scale web data collection

  Run hundreds of concurrent browsers against JavaScript-heavy sites without provisioning or babysitting a Chrome fleet.

• •
  Automated end-to-end testing

  Drive test flows with LLM-interpreted navigation so tests survive layout changes that break selector-based suites.

• •
  Sales and GTM data enrichment

  Gather firmographic and contact signals from public web sources at concurrency, as customers such as Clay do.

• •
  Business process automation across SaaS

  Automate multi-step work spanning several web applications where no single API covers the whole flow.

Pricing is published and metered on browser hours plus concurrency, with proxy bandwidth, agent runs and fetch calls as secondary meters. Paid tiers run $20 and $99 a month with included hours, then $0.12 and $0.10 per browser hour respectively beyond them; the free tier gives one browser hour and three concurrent browsers. HIPAA, a DPA and SSO are gated behind the custom-priced Scale plan. The vendor's own rule of thumb is that a typical scrape runs under two minutes, so 100 hours is roughly 3,000 page-level tasks — model your own task duration before comparing tiers.
