Browserbase
Browserbase is a browser-agent platform that provides managed, headless Chromium browsers and supporting web primitives for AI agents and automation workloads. Customers use a single API key to spin up sessions, fetch and search the web, persist context, route LLM calls, and observe agent behavior across replays and logs. The company maintains the popular open-source Stagehand SDK, a Director UI for agent design, a Browse CLI, and an MCP server. Target customers are AI startups, agent developers, RPA teams, and enterprises running production web automation, with SOC 2 Type II and HIPAA options. Billing is usage-based with a free tier and paid plans on the pricing page.
Browserbase publishes 12 API contracts indexed on the APIs.io network, including Contexts API, Extensions API, Projects API, and 9 more. Tagged areas include Browser Automation, Browser Infrastructure, AI Agents, Web Scraping, and Stagehand.
The Browserbase catalog on APIs.io includes 1 JSON-LD context and 2 Spectral governance rulesets.

Kin Score
Markets this provider is in provisional
The Kin Score Market layer reads a provider inside its market: its position, and how deep its integrations go. Depth is only comparable within a position. Provisional and unweighted: not part of the Kin Score or agent readiness.
| Market | Position | Depth | Registered MCP server | Declares compatibility |
|---|---|---|---|---|
| Agent Skills (SKILL.md packages) | builds-on | 37.0 | - | 1 |
| Stripe App Marketplace and Partner Ecosystem (builders on Stripe) | builds-on | 37.0 | - | 1 |
| Jamstack Hosting Integrations (Vercel Marketplace and Netlify Integrations publishers) | builds-on | 37.0 | - | 1 |
Registered MCP server and declares compatibility are report only — not weighted. Undeclared means we found nothing we can read, so there is no number: we never infer integrations.
