Playwright vs Browserbase
Playwright MCP and Browserbase MCP both let an agent drive a real browser, but they make opposite infrastructure bets. Playwright, Microsoft's official server, runs the browser locally and exposes pages as structured accessibility snapshots, giving you a free, deterministic, self-hosted option. Browserbase runs the browser in its cloud and drives it with Stagehand's natural-language actions, trading a per-session fee for zero local infrastructure. This is the comparison most teams face after the legacy Puppeteer reference server was deprecated, so here is a balanced look at how the two differ on where the browser runs, how the agent interacts with the page, cost, and the kind of work each suits best.
How they compare
| Dimension | Playwright | Browserbase |
|---|---|---|
| Where the browser runs | Locally on your machine or your own host; you launch it over stdio with npx. | In Browserbase's cloud, so nothing runs locally; ideal for serverless and CI. |
| Interaction model | Structured accessibility snapshots plus explicit tools like click, type, and navigate; deterministic and token-efficient. | Natural-language actions through Stagehand (act, observe, extract); the server figures out how to carry out an intent. |
| Cost | Free and open source; you pay only for any infrastructure you run yourself. | Cloud browser sessions are a paid product (with a free tier), and you also supply an LLM key for Stagehand. |
| Browser coverage | Chromium, Firefox, and WebKit, with a large tool surface for tabs, network, forms, and PDFs. | Managed cloud browsers with a small, high-level six-tool surface focused on intent and extraction. |
Verdict
Neither server is strictly better, they fit different constraints. Choose Playwright when you want a free, deterministic, locally-controlled browser with broad cross-browser coverage and fine-grained tools, which is most local development and testing. Choose Browserbase when you need to automate the web from an environment where running a browser is impractical, such as a serverless function or CI runner, and you are comfortable paying per session for managed infrastructure and natural-language control. Many teams start with Playwright locally and reach for Browserbase when they need to scale or run headless in the cloud.
FAQ
- Why not Puppeteer?
- The original @modelcontextprotocol/server-puppeteer reference server is deprecated and unmaintained, so Playwright and Browserbase are the current well-supported options.
- Can I use both?
- Yes. They are independent MCP servers; you can register Playwright for local work and Browserbase for cloud or CI in the same client.
