Browserbase vs Playwright MCP Server

The question is where the browser runs. Playwright is official, free, and local: real Chromium, Firefox, and WebKit on your machine, with auto-waiting selectors and trace-based debugging, and no credential at all. Browserbase is official and hosted: browser sessions in someone else's infrastructure, with concurrency, anti-bot resilience, and sessions that persist across runs, on a freemium API key.

Choose by scale and by who is blocking you. Cross-browser testing and debugging a flaky selector are Playwright's home ground - and its trace output is the reason to prefer it while you are still figuring out why something fails. Running many sessions at once, needing different geographies, or hitting anti-bot defenses is where local Playwright stops being practical and Browserbase earns its cost.

Watch the economics rather than the features. Browserbase's own listing flags hobbyist budgets and heavy data-out scenarios as poor fits, because egress adds up. Playwright's flags resource-constrained environments, which is the polite way of saying a dozen Chromium processes will hurt a laptop. Start with Playwright since it costs nothing, and move to Browserbase at the point where concurrency or blocking - not preference - forces the change.
