Nope! Moved away from using CF rendering.

highvoltage•5/29/25, 11:24 PM

Hey CF team. I'm having trouble using the Browser Rendering binding in one of my workers to render a PDF of a web page. This was previously working ealier this month, but now the page.createPDFStream method is not returning a stream. Using page.pdf returns "Cannot create buffer". Any ideas on what would cause this?

Razmjoo•6/3/25, 3:47 PM

Hello everyone, what is the best way to increase the rate limit on the browser rendering rest api? My account is set to startup/enterprise, so I assume it is configured to the default (60 r/min). We don't use this API constantly; however, when we do, we will have spikes in our usage for a short time, then it drops back to zero (it might increase later on) (unfortunately, our workflow is triggered by demand, and we can't schedule them in advance).

Kathy•6/3/25, 8:47 PM

if you are on a paid plan, you can request higher limits here https://developers.cloudflare.com/browser-rendering/platform/limits/#workers-paid.

we ask that you only submit reqest if you're actively hitting limits as increasing limits requires manual action at this time and we want to prioritize customers who truly need the additional capacity. We're working on raising limits for everyone across the board, so this will become less of an issue in the future

hey team - do you plan to remove this limitation?

Browser Rendering is not supported locally. Please use `wrangler dev --remote` instead.

Very quick question before I spend sometime looking into this, I generate images from my worker app as react components, css/html. I’m using puppeteer to take screenshots of the component and turn them into .png. Can I incorporate this instead of puppeteer? Or is it as well as puppeteer?

LLuney Consider something like https://developers.cloudflare.com/pages/functions/plugin...

U.Senthil Kumar | Contributor•6/15/25, 1:03 PM

Great suggestion! Using @vercel/og@vercel/og via Cloudflare Pages Functions is definitely faster and more efficient than browser-based rendering, perfect for generating dynamic PNG/SVG from React components at scale.

rodders1013•6/15/25, 5:39 PM

@Luney @U.Senthil Kumar | Contributor I fully agree with vercel og/satori , in fact I used it originally when I was using vercel, before I decided to go down the cloudflare route. I might re look at it, as I was coming up with some issues passing in the component, it would defo be better,

U.Senthil Kumar | Contributor•6/15/25, 5:43 PM

i agree with vercel og/satori, i used it before when i was using vercel. then i changed to cloudflare. maybe i will try it again, before i had some issues with adding the component. but yeah, it’s definitely better.

Simun•6/16/25, 1:34 AM

Would anyone happen to know the time limit on browser rendering for Workers Paid accounts? The docs here say that free only gets 10 minutes while paid gets an unspecified number, is it limitless or just higher by some amount?

Kathy•6/16/25, 4:34 PM

hey! we are working on pricing/billing for Browser Rendering right now. Pricing will be announced soon, with billing starting shortly after. Until then, for Workers Paid usage is limitless but once we start billing, you will pay for usage over the included amount in the Workers Paid plan

Getting this below error when I launch @Cloudflare/puppeteer like below in remote

  const browser = await puppeteer.launch(env.VIRTUAL_BROWSER, {});

  const browser = await puppeteer.launch(env.VIRTUAL_BROWSER, {});

ByteBeast•6/17/25, 8:32 AM

How can I use virtual brower in local, I want to use it in local, its now working in remote mode also

ByteBeast•6/17/25, 10:08 AM

Getting so many debugging log when I launch cloudflarePappter browser at beginning and use it to load more then one URL like below.
How can I stop this logs?

const page = await browser.newPage();
await page.goto(url, { waitUntil: "networkidle2", timeout: 100000 });

const page = await browser.newPage();
await page.goto(url, { waitUntil: "networkidle2", timeout: 100000 });

this is how I launch

  const browser = await puppeteer.launch(env.VIRTUAL_BROWSER, {});

  const browser = await puppeteer.launch(env.VIRTUAL_BROWSER, {});

when I launch browser just before I want to use i ma not getting any kind of debugging logs like below

  const browser = await puppeteer.launch(env.VIRTUAL_BROWSER, {});
  const page = await browser.newPage();
  await page.goto(url, { waitUntil: "networkidle2", timeout: 100000 });

  const browser = await puppeteer.launch(env.VIRTUAL_BROWSER, {});
  const page = await browser.newPage();
  await page.goto(url, { waitUntil: "networkidle2", timeout: 100000 });

How can I stop this debugging logs?

not yet. what model would you like to use?

Lloyd•6/22/25, 9:58 PM

We currently roll our own service for this, but are looking at the rendering API as a replacement. I was wondering if as it is a CF service, are CF pages/turnstyles/I'm Under Attack modes gracefully dealt with when taking a screenshot of a target page?

James•6/23/25, 12:46 PM

Can https://github.com/cloudflare/puppeteer/issues/91 please be re-opened? And can we please remove stalebot?

NeonSpectre•6/23/25, 9:00 PM

I have been trying to use pupeteer in browser rendering worker binding and the worker logs are just filled with debug logs from pupeteer/browser rendering. Is debug logging enabled by default? how do we stop that. I am not able to see any other logs because it reaches log limit. Here is one of the logs how it looks like

"{"method":"Network.requestWillBeSent","params":{"requestId":"67.89","loaderId":"464922953717C3B69047","docum...

"{"method":"Network.requestWillBeSent","params":{"requestId":"67.89","loaderId":"464922953717C3B69047","docum...

NeonSpectre•6/23/25, 9:00 PM

Is the recommended approach to use browser rendering apis instead of the worker binding?

JJon M.I thought Pupeteer wasn't supported in CF Browser Rendering?

NeonSpectre•6/23/25, 10:32 PM

Pupeteer and Playwright are both supported. Docs here - https://developers.cloudflare.com/browser-rendering/platform/puppeteer/

Oleg Isonen•6/24/25, 8:28 AM

Hi, anybody runs into issues where some parts of the website are not correctly rendered via API while it works correctly locally? We have a heavy suspicion it's a GPU issue.

Anything that has a css blur seems to be the issue.

Connor•6/25/25, 10:05 AM

So when you use the Cloudflare Typescript SDK to capture a screenshot, where is the screenshot data? The promise is not returning a Response so I can't just return it in the worker. A bit confused. https://developers.cloudflare.com/browser-rendering/rest-api/screenshot-endpoint/#basic-usage

Cloudflare Docs

/screenshot - Capture screenshot

The /screenshot endpoint renders the webpage by processing its HTML and JavaScript, then captures a screenshot of the fully rendered page.

NeonSpectre•6/25/25, 11:31 PM

Is is possible to specify the region from which the browser rendering should load the page and take the screenshot?

Rui Figueira•6/26/25, 4:18 PM

@ByteBeast @Jon M. @NeonSpectre I also had the same puppeteer logging issue. puppeteer logs using debugdebugmodule but in cloudflare workers, unenvunenv polyfills it. I opened a PR to fix it:

https://github.com/cloudflare/puppeteer/pull/128

GitHub

In cloudflare workers, debug module fallbacks to unenv, which calls console.debug:

JJon M.I ended up having to integrate with Browserless.io instead.

Rui Figueira•6/26/25, 4:33 PM

ok, but if you want to stay in cloudflare ecosystem, there's playwright support and it doesn't have the logging issue
