Browserbase

什麼是 Browserbase？

Browserbase is a browser infrastructure platform for building agents that need to interact with the live web. It provides real browser sessions, Search and Fetch APIs, and identity tooling so software can navigate pages, extract content, and complete actions that typical APIs cannot reach.

The platform is positioned for workflows such as research, lead enrichment, price tracking, form completion, and file handling. Its browser layer is designed to work at scale, with on-demand sessions, configurable environments, and an SDK integration through Stagehand.

Browserbase 能做什麼？

Concurrent Chromium sessions

Run browser sessions on globally distributed infrastructure with isolated environments and no shared state between sessions.

Fully configurable browser environment

Configure cookies, extensions, proxies, uploads, and downloads so each session matches the task requirements.

Instant spin-up

Launch sessions on demand without cold starts and scale from one browser to thousands without provisioning clusters.

Verified agent identity

Use Web Bot Auth to provide a cryptographically verified agent identity that websites and anti-bot providers can trust.

Search and Fetch primitives

Search and Fetch APIs help agents locate pages and extract content before taking actions in a browser.

Security and session isolation

Secure sessions with encrypted connections, credential management through 1Password, and no data persistence between runs.

使用情境

“Research agents”

Point an agent at a topic or target site, use search to find the right pages, then extract readable content for analysis or follow-up actions.

“Lead enrichment”

Search for a company or contact, fetch the relevant page, and return the structured information needed to enrich records.

“Competitive monitoring”

Track prices, job postings, product changes, and competitor updates by running repeated browser workflows across the live web.

“Web task automation”

Handle browser-based tasks that require forms, logins, CAPTCHAs, or file downloads, including vendor portals and government forms.

常見問題

What does Browserbase do?

Does Browserbase have paid plans?

The pricing page shows a free starting point plus paid Developer, Startup, and custom Scale plans. It describes usage-based browser agent infrastructure rather than a fixed one-size-fits-all plan.

What kinds of workflows does it support?

Browserbase supports launch-on-demand browser sessions and says sessions can be used for tasks such as research, lead enrichment, and competitive monitoring. The source also references Stagehand as an SDK integrated with the platform.

How does Browserbase handle identity and login state?

The source says Browserbase Identity provides Web Bot Auth, credential access through 1Password, and session persistence through the Contexts API. It is presented as a way to give agents a verifiable identity across runs.
