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.

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?

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 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 });

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, {});

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

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?

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...

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?

N

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.

C

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.

N

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?

Hi, I have some security related questions on how the Playwright MCP server works.

I was able to integrate the playwright MCP agent onto my hono backend app, and i was able to connect my Claude desktop to my local worker with a remote binding on the browser. it's really cool, but it's hard to tell what's going on.

is there idea that there is a persistent web browser connection during the lifetime of the chat session? if so, would every connection get its own browser instance / would they be shared across connections?

in general, are there recommendations on how to compose playwright MCP with specific kinds of tasks? for example, i think it could make sense to define separate playwright MCPs per web application with custom tools that are built to interact with those websites, but it sort of looks like the playwright MCP is meant to be a general purpose browser agent with only basic primitives.

I'm building a webperf tester (e.g. say similar to PageSpeed Insights) but on top of CF Puppeteer. I saw turnstile/bot challenges on some Cloudflare zones, but I'm surprised that Cloudflare's Radar itself also does get challenged.

I guess this is bot traffic so it makes sense. Would the expected behavior be that any domains who aggressively block bots should allow explicitly (via custom header or user-agent)? Or if you hit enough traffic (+1k requests/day) apply to be a verified bot?

Hello friends. I can not seem to auth with the browser rendering api, I am trying to CURL on my local system. I've checked the token's permissions, Browser Rendering - Edit is set. I checked the token itself. But I keep getting a 401 {"result":null,"success":false,"errors":[{"code":10000,"message":"Authentication error"}],"messages":[]}%

Do these api calls only work from workers running on cloudflares internal network? Or is my request malformed? Thanks a ton for any help

curl -X 'POST' 'https://api.cloudflare.com/client/v4/accounts/******/browser-rendering/content' \
-H 'Content-Type: application/json' \
-H 'Authorization: Bearer *' \
-d '{"url": "https://example.com"}'

Edit: Looks like this api endpoint only works with User scoped tokens, not account tokens. Is that true?

Final edit: I was using a bad token, I'll see myself out.
