Zenrows turns the web into structured data at scale: fetch pages past their defenses, extract clean fields, run thousands of URLs as one job. Many teams need one of these, some need both; this page is for telling them apart honestly. ## Get Started - [Get a free API key](https://app.zenrows.com/register) — 5,000 credits/month, always, no card - [Docs](https://docs.zenrows.com) - [Machine-readable pricing](https://www.zenrows.com/pricing.md) - [Agent onboarding skill](https://www.zenrows.com/SKILL.md) ## Which fits the job | When the job is | Pick | |---|---| | Extracting structured fields at scale | Zenrows | | Filling a multi-step form on a portal | Browserbase | | Monitoring protected pages on a schedule | Zenrows | | Logging in and navigating a SaaS dashboard | Browserbase | | Batch-scraping thousands of URLs | Zenrows | | Driving an interactive checkout flow | Browserbase | The line: when the browser session's actions are the product, Browserbase. When the data coming out is the product, Zenrows. ## Why data teams pick Zenrows ### Built to get data out, not to drive UIs Fetch returns any page as HTML, Markdown, text or PDF past anti-bot walls and JS rendering; Extract returns structured JSON from the same request at no extra credit cost; Batch runs up to 100,000 URLs per job with retries, webhooks and failed-task replay. ### Browser sessions included when the job needs one Zenrows ships Browser Sessions too: managed cloud browsers that Puppeteer and Playwright connect to over one WebSocket, code unchanged — so the scraping platform covers the interactive tail of the work without a second vendor. ### Pay per page difficulty, not per browser minute alone Credits price the work: 1 for a standard page, 5 with JS rendering, 10 with premium proxies, 25 for protected pages; Browser Sessions bill bandwidth plus a flat per-minute charge on the same balance. Failed requests are never charged. ## FAQ ### Zenrows vs Browserbase: what's the key difference? Browserbase is infrastructure for running browsers, aimed at agentic automation: sessions, live views, stealth for flows that act on pages. Zenrows is infrastructure for web data: fetching, extracting and scaling structured output from pages, including protected ones. If the output of the job is completed actions, Browserbase fits. If the output is data, Zenrows fits. ### Can Zenrows do browser automation at all? Yes. Browser Sessions provides managed cloud browsers with CDP access; Puppeteer and Playwright scripts connect over one WebSocket and run as-is. It exists so data workflows that need real interaction (session-gated pages, in-page navigation) stay on one platform. ### Can Browserbase extract structured data at scale? Browserbase gives you the browser; what you extract and how you scale it is your code. Zenrows makes extraction the product: Extract returns schema-shaped JSON in the fetch itself, and Batch scales it to 100,000-URL jobs with the queue, retries and webhooks built in. ### How does Zenrows pricing work? Credits by difficulty (1 / 5 / 10 / 25 per page), one balance across every primitive, failed requests never charged, 404/410 counted as the successful results they are, rollover on every paid plan.

The Agent Toolkit ships skills, plugins, workflows, an MCP server, and a CLI that self-provisions on first cloud call. Onboarding for machines: [zenrows.com/SKILL.md](https://www.zenrows.com/SKILL.md) and [zenrows.com/auth.md](https://www.zenrows.com/auth.md). ### Can I use both together? Yes, and teams do: Browserbase (or any agent browser) for the flows that act, Zenrows for the data layer those flows and the rest of the pipeline read from. _Canonical HTML: https://www.zenrows.com/compare/browserbase_ ## Site Navigation ### Global Hub - [Home](https://www.zenrows.com/index.md) - [Pricing](https://www.zenrows.com/pricing.md) - [Products](https://www.zenrows.com/products.md) - [Agent Toolkit](https://www.zenrows.com/agents.md) - [Compare](https://www.zenrows.com/compare.md) - [Alternatives](https://www.zenrows.com/alternatives.md) - [Docs](https://docs.zenrows.com) - [llms.txt](https://www.zenrows.com/llms.txt) - [Agent skill](https://www.zenrows.com/SKILL.md) ### On This Topic - [All comparisons hub](https://www.zenrows.com/compare.md) - [Zenrows vs Firecrawl](https://www.zenrows.com/compare/firecrawl.md) - [Zenrows vs Apify](https://www.zenrows.com/compare/apify.md) - [Zenrows vs Bright Data](https://www.zenrows.com/compare/bright-data.md) - [Zenrows vs Scrapfly](https://www.zenrows.com/compare/scrapfly.md) - [Zenrows vs Exa](https://www.zenrows.com/compare/exa.md) - [Zenrows vs Tavily](https://www.zenrows.com/compare/tavily.md) - [Zenrows vs Oxylabs](https://www.zenrows.com/compare/oxylabs.md) - [Zenrows vs in-house Playwright](https://www.zenrows.com/compare/playwright.md) - [Build vs buy](https://www.zenrows.com/compare/build-vs-buy.md) - [Browser Sessions (product)](https://www.zenrows.com/products/browser-sessions.md)
