How to Scrape Dynamic Websites with Hyperbrowser
Hyperbrowser is a hosted browser-automation API: you send a URL, it loads the page in a real headless browser and returns markdown, HTML or structured data. Because the browser runs remotely, it handles JavaScript-rendered content that a plain HTTP fetch would miss.
It sits between a simple scraper and a full Playwright setup you maintain yourself. You give up control of the browser environment and skip the part where Chrome crashes on a server at 3 a.m.
How do you scrape your first page?
- Create an account and copy your API key.
- Call the scrape endpoint with a target URL and output format.
- Read the returned markdown or HTML.
A single scrape request looks like this:
POST https://api.hyperbrowser.ai/api/scrape
Authorization: Bearer YOUR_KEY
{ "url": "https://example.com", "formats": ["markdown"] }Markdown output is the reason to use it. You get readable text stripped of navigation and ads, which is exactly what a downstream LLM wants.
What kinds of sites does it handle?
Anything that needs a real browser:
- Single-page apps that render content in JavaScript.
- Infinite-scroll pages where you need more than the first screen.
- Pages behind a simple interaction, like clicking a tab to load a table.
If your target is static server-rendered HTML, a plain request library is cheaper and faster. Reaching for a browser API on a static page is paying for capacity you do not need.
Is Hyperbrowser free?
There is a free tier with a monthly allowance of credits or browser minutes, then usage-based pricing for higher volume. Browser time is the unit that matters — one minute of headless browsing costs far more than one HTTP request. A scrape of a heavy site can take several seconds, so small allowances disappear faster than you expect.
What will get you rate-limited?
Hammering one domain in parallel is the fastest route to blocks. Use their session and proxy features to rotate, and keep concurrency per domain low. Two requests at a time against the same host is usually safe; twenty will get the IP banned and waste your credits on challenge pages.
Also respect robots.txt and terms of service. Automated browser access is not a licence to ignore them, and a blocked account is harder to fix than a slower scraper.
Where does it get expensive?
Large crawls. Scraping ten pages is cheap; scraping ten thousand is a real bill, because each page spins a browser session. For anything more than a few hundred pages, evaluate whether a static-request path can cover most URLs and reserve the browser API for the pages that genuinely need JavaScript.
Quick Summary
- Hyperbrowser runs headless browsers in the cloud and returns markdown, HTML or data.
- Best for JavaScript-rendered pages and single-page apps.
- Free tier with a monthly allowance, then usage-based pricing by browser time.
- Rotate sessions and limit concurrency to avoid IP blocks.
- Large crawls get costly — use plain requests for static pages.
