Browserbase

Browserbase is a platform for giving AI agents access to the web. Rather than building browser infrastructure from scratch, developers use its primitives to run agents that can log in, fill forms, click through portals, and retrieve data from sites that offer no API.

The platform bundles cloud browsers, a scalable sandboxed runtime, managed browser agents driven by simple prompts, search and fetch endpoints that return agent-ready HTML, JSON, or markdown, and identity tools for authentication. Observability unifies replays, logs, and prompts for debugging, and any model can be used with a single API key.

Open-source components lower the entry barrier: the Browse CLI adds browsing skills with one command, while Stagehand is a widely used AI browser automation framework. Solution pages map these capabilities to concrete jobs such as KYB and background checks, portal filings, document retrieval, data migration, and permissioned access to payroll or patient portals.

It is aimed at developers and engineering teams building browser agents, as well as operations and data teams automating repetitive portal work. Those wanting a no-code product may find it too low-level, and pricing details are not shown on this page, so check the site directly.

A reasonable approach is to start with the open-source CLI or Stagehand, then move to managed browsers and the runtime as workloads grow. In short, it is infrastructure for agents that need to use the real web.
