Input and output
Turn a URL or HTML payload into the artifact your workflow needs.
Use one API surface for screenshots, PDFs, visual diffs, metadata, and LLM-ready content extraction.
PDF export
Generate documents with page format, orientation, and background graphics for invoices, reports, and evidence.
Content extraction
Return markdown, HTML, plain text, and metadata beside a screenshot for AI agents and analysis workflows.
Visual diff
Compare two URLs pixel-by-pixel and return changed pixels, diff percentage, and a highlighted diff image.
Batch capture
Render up to 10 URLs in one request with bounded parallelism through the browser pool.
Async webhooks
Queue heavier jobs, return a job ID immediately, and notify your application when the capture finishes.
Clean captures
Screenshots without the clutter that ruins reports.
Block ads, trackers, cookie banners, fonts, media, or your own selectors so every capture is consistent enough for audits, research, and customer-facing workflows.
Ad and tracker blockingGhostery-powered rules keep noisy pages under control.
Device emulationMobile viewport, timezone, geolocation, and dark mode.
Custom CSS and JSInject page fixes before the screenshot is taken.
Deterministic cache keysEvery output-changing option becomes part of the cache key.

Use cases
Built for teams that need screenshots to be evidence, not decoration.
Research monitoring
Track pages, competitors, and market changes on a schedule.
Compliance audits
Archive proof of what users, vendors, or public pages showed.

Compare deploys and catch layout changes before customers do.
AI agents
Give agents screenshots plus markdown context in one request.
Marketing assets
Generate consistent product, website, and report visuals.
How it works
From request to cached artifact in a few predictable steps.
The browser pool renders the page once, applies capture options, stores the output when needed, and serves repeat requests from cache.
1
Request
URL, HTML, and render options.
2
Render
Browser pool loads and prepares the page.
3
Capture
Image, PDF, diff, or JSON payload.
4
Return
Stream, store, cache, or webhook.
Free start
