Browserbase & Stagehand vs Playwright

Managed headless browser infrastructure against running the same library on your own machines.

Browserbase & Stagehand is managed headless browser infrastructure with session replay, plus an AI agent layer that drives pages from natural language. It is maintained by Browserbase, runs on Cloud · Playwright/Puppeteer CDP · Stagehand SDK, and starts at free tier · from $39 / mo.

Playwright is headless Chromium, Firefox and WebKit with per-context proxies — the default engine for JavaScript-rendered scraping targets. It comes from Microsoft, runs on Node · Python · .NET · Java, and starts at Free.

The library is identical — Browserbase is a place to run it. Self-hosting is cheaper per browser-hour once utilisation is steady; Browserbase is cheaper in total when your load is spiky or your team should not be operating a browser fleet.

We score every scraping tool on five axes that decide real projects: how quickly a new engineer becomes productive, how far the tool scales before it needs replacing, how well it survives anti-bot systems, how good the documentation and community are, and what you get per dollar. Browserbase & Stagehand scores 8.3/10 overall against 9.3/10 for Playwright, but the aggregate hides the trade-off that matters to you.

The clearest gaps are on value for money and scale. Read those two rows first; the rest are close enough that team familiarity should decide.

Throughput decides your proxy bill as much as your compute bill: a tool that needs a full browser to read a page transfers ten to thirty times more bytes than one that parses HTML directly, and residential bandwidth is priced per gigabyte.

Browserbase & Stagehand sustains Concurrency-limited by plan and uses roughly None (remote). Playwright sustains 8 – 40 pages/min per worker at roughly 250 – 600 MB per context. On JavaScript-heavy targets, Browserbase & Stagehand handles rendering like this: Full, managed Chromium Playwright: Full — Chromium, Firefox, WebKit

Browserbase & Stagehand: Billed by browser-hours and concurrent sessions; proxy bandwidth is metered separately.

Playwright: Apache-2.0. Real cost is CPU and RAM: a browser page uses 40–120× the memory of an HTTP request.

Neither list price is your real cost. Add proxy bandwidth for every tool that does not bundle it, add the compute hours for anything that drives a browser, and add the engineering time that a self-hosted stack consumes every month. A framework that is free to license routinely costs more per delivered page than a paid unlocker once residential gigabytes and failed requests are counted honestly.

Proxy strategy is where most scraping projects leak money. Browserbase & Stagehand expects: Built-in residential proxies per session, or bring your own Managed pool by default; bring-your-own proxy URLs once volume justifies a direct contract.

Playwright expects: Per-browser and per-context HTTP/SOCKS5 proxies with username auth Attach the proxy per browser context so one identity keeps one exit for a whole session.

Whichever tool you pick, tier your proxy network per domain rather than globally. Start every target on datacenter IPs, promote it to rotating residential when the block rate on that specific domain passes a few percent, use static ISP IPs for anything logged in, and reserve mobile exits for app-only endpoints. Teams that apply one proxy type to every target routinely overpay by five to ten times.

Neither tool is strictly better. The lists below are the differences that changed our recommendation during testing, not feature-sheet trivia.

The library is identical — Browserbase is a place to run it. Self-hosting is cheaper per browser-hour once utilisation is steady; Browserbase is cheaper in total when your load is spiky or your team should not be operating a browser fleet.

Choose Browserbase & Stagehand when: Spiky agent workloads, no ops capacity, and a need for session recording, stealth defaults and instant scale-out.

Choose Playwright when: Steady, predictable concurrency where a container fleet you already run costs a fraction of managed browser minutes.

A large share of production stacks run both. Using Browserbase & Stagehand for the bulk of the crawl and Playwright for the fraction of domains it handles better is almost always cheaper than forcing one tool to cover every target, because the expensive path only gets used where it earns its price.
