Both run managed browsers so you don't maintain your own Chromium servers. Cloudflare Browser Run, formerly Browser Rendering, takes screenshots of HTML or a URL through a REST API, with viewport, full-page, clipping, and timing controls. Both also output PDFs.
Browser infrastructure right next to your Workers application. Use Quick Actions for a screenshot or PDF, or drive a full browser session through Puppeteer, Playwright, or CDP. That makes it a good fit when you're also crawling pages, extracting content, or running custom browser steps.
Cloudflare runs the browser. Saving and serving the images, caching repeat requests, filling in template variables, and retrying failures are up to you. If you already use Workers and R2, those pieces can fit naturally into your stack.
HTML/CSS to Image connects them: a visual designer and saved templates, signed template URLs that create images on request, hosting and CDN delivery, and application-level deduplication. Reusing an existing image URL never consumes another credit.
HTML/CSS to Image
Hosting and CDN delivery are included. Application-level caching keeps an existing image URL reusable, even after a CDN cache miss, without consuming another image credit.
Paid plans keep images while your account is active. Custom-storage-only images use your own delivery.
Cloudflare Browser Run
The screenshot endpoint returns image output. Connect it to your own storage, delivery, and cache logic.
Cloudflare applies separate limits to Quick Actions, at 30 requests per second on Workers Paid, and to browser sessions, at 200 concurrent browsers by default and three new instances per second. Paid limits can be raised on request. HTML/CSS to Image has no concurrency caps or per-minute limits on creating and rendering images.
HTML/CSS to Image
Send image creation and rendering requests in parallel, with no concurrency caps or per-second or per-minute rate limits.
Image credits and plan limits still apply.
Cloudflare Browser Run
Workers Paid allows 30 Quick Actions requests per second. Browser sessions have a default 200 concurrent-browser limit and three new instances per second.
Plans and pricing
Cloudflare charges for browser time. Quick Actions use browser-hour billing, and browser sessions also have a concurrency charge. Workers Paid includes 10 browser hours a month, then $0.09 per additional hour. Session concurrency is billed on the monthly average of your daily peak browser count: 10 included, then $2 per additional browser.
Add your Workers plan, storage, and delivery to those browser costs. HTML/CSS to Image prices the whole workflow per created image, with hosting, reuse, and output variants included.
$14/month for 1,000 images on Basic.
Includes templates, the visual editor, and hosted image delivery. A free plan includes 50 images per month.
Workers Free includes 10 minutes of browser time per day.
Free usage is time-based rather than an image allowance.
$69/month for 10,000 images on Basic.
Optional overages cost $10 per 1,000 images. Includes templates, hosted image delivery, storage destinations, and bring-your-own proxies at this volume.
Browser-time billing, plus your Workers plan and image storage and delivery.
Browser-session concurrency adds a separate charge, which doesn't apply to Quick Actions.
It can be, for short captures. Workers Paid includes 10 browser hours a month, then $0.09 an hour, and browser sessions add a concurrency charge. Storage and delivery are extra. HTML/CSS to Image charges per image, from $14/month for 1,000, with hosting included.
Yes. Cloudflare renamed Browser Rendering to Browser Run.
No. The screenshot endpoint returns the image, and storing and serving it is up to you, often with R2. HTML/CSS to Image returns a hosted image URL with CDN delivery included.
Not out of the box. You'd build the HTML and fill in the variables in your Worker. HTML/CSS to Image has saved templates, a visual editor, and signed template URLs.
