Data extraction that returns clean results
The web wasn't built for agents. Browserbase runs data extraction on real cloud browsers that render JavaScript, reach pages that turn away ordinary tooling, and return structured data. Describe what you need and the Stagehand SDK returns it as typed JSON, with no per-site tuning.
The Problem
Extracting data from the web is fragile by design
- Static tools miss data on JavaScript-rendered and single-page sites.
- Bot detection blocks scripted requests before the extraction finishes.
- Hard-coded CSS selectors break every time a site changes its layout.
- Every new source needs its own custom parser to maintain.
- Raw output still needs cleanup before it can land in a database.
The Solution
How Browserbase powers reliable data extraction
- Real browser rendering: full Chrome instances execute JavaScript, load SPAs, and handle infinite scroll and pagination.
- Fetch for speed: pull static pages over lightweight HTTP and fall back to a full browser only when a page needs it.
- Natural language extraction: describe the data you need in plain English. The Stagehand SDK finds and returns it as structured JSON.
- Schema-typed output: define a schema and get clean, typed data ready for your database, with no post-processing.
- Self-healing selectors: when a site changes its layout, the extractor re-identifies the right elements automatically.
- Verified: every session reaches pages that turn away ordinary tooling, with residential proxies and managed CAPTCHA solving included.
- Agent Identity: Web Bot Auth signs your agent's requests, so sites can verify it instead of guessing.
- Parallel at scale: run thousands of browser sessions simultaneously to extract from large sources fast.

Frequently Asked Questions
What is data extraction?
Data extraction is the process of pulling specific information from a source, such as a website, and returning it in a structured format. Browserbase runs extraction on real cloud browsers, so it can reach pages that static tools miss and return clean, typed data.
How does automated data extraction work?
You point the extractor at a page, describe the data you want, and it returns that data as structured output. On Browserbase, each page loads in a full Chrome session, so JavaScript-rendered content is available exactly as a person would see it.
Do I need a full browser for every page?
No. Use Fetch for lightweight HTTP retrieval on static pages, and fall back to a full browser session for JavaScript-heavy ones. The smart-fetch-scraper template does exactly this, so large extraction jobs stay fast and cost-efficient.
Can I get the data in a specific format?
Yes. With the Stagehand SDK you define a schema in TypeScript or Python, and the extractor returns data matching that exact structure. You get clean, typed JSON ready for your database or API, with no post-processing.
Can I extract data from a website into a spreadsheet?
Yes. Extraction returns structured JSON or CSV, which loads directly into a spreadsheet, database, or downstream pipeline. You can run it once or on a schedule to keep the data current.
What sources can Browserbase extract from?
Any site a person can visit, including JavaScript-heavy single-page apps and pages behind login walls using persistent contexts. Verified access and residential proxies come with every session.
Can I extract from thousands of pages at once?
Yes. You can run thousands of browser sessions in parallel in the cloud and write results straight to clean, typed JSON, CSV, or your database.
