(could be unrelated but) we're also seeing an odd spike in some timings collected by Browser Rendering (Puppeteer) since the 12th of July early morning UTC

katu•7/14/25, 11:06 AM

Hi, I see there has been talk about WebGL before. It's a bit of a make-or-break point for me, and the fact that it's not supported is probably going to drive me to other browser rendering products. Wondered if there's any plans on this front? It was also frustrating to find this out in practice, since it doesn't appear to be mentioned in any docs.

It turns out we had to add another “wait for idle network” call during the print flow which wasn’t needed before, weirdly enough. Not sure what made this change needed, we hadnt changed anything for over a week when the behaviour change happened.

juanferrerasOP•7/14/25, 12:43 PM

thanks! that makes sense, I haven't checked my logs but there must have been a change of infrastructure/location/etc that could make certain things take longer/timeout for example

thasmo•7/14/25, 6:03 PM

Hey!

I'm using the Cloudflare PDF REST API to render a URL to PDF and weirdly enough it seems that for a reason I can't find, the only image on the page does not render in the PDF. When using the native puppeteer client from localhost I have no issues rendering the PDF with the image. I'd assume that either Cloudflare does not load the image for some reason or the remote host (Netlify) does block the request from Cloudflare, although the request for the actual HTML file is just fetch correctly by Cloudflare. Are there any known issues regarding image loading or any related topics? Thanks a lot!

Kathy•7/15/25, 9:20 PM

thanks y'all for the reports on timing issues over the weekend. this should be resolved now. please let me know if not @katu @juanferreras @Mohammed K

katu•7/16/25, 7:50 AM

Hey I actually asked about something different

WebGL support

JJon M.Ya @Kathy , let's have that now 😉

katu•7/16/25, 5:07 PM

I can understand why it’s a complex thing to offer though. WebGL then implies need for substantial GPU resources (I would need this too!)

Kathy•7/16/25, 7:35 PM

WebGL is on the list of things to do @katu @Jon M.

Jjuanferreras hey all! is there any (very rough) ETA for the new pricing announcement?

Kathy•7/16/25, 7:35 PM

pricing is out https://developers.cloudflare.com/browser-rendering/platform/pricing/

what i wonder more about is if theres a built in way to limit concurrency? like a queue or do i need to keep track of this myself? im not expecting to hit 10+ concurrent ones but still interesting to know

Kathy•7/17/25, 4:55 PM

you can use queues or reusing sessions will help too. +if you're worried about cookies between sessions you can use incognito context (https://pptr.dev/api/puppeteer.browser.createbrowsercontext) and not worry about pollution

Browser.createBrowserContext() method | Puppeteer

Creates a new browser context.

Silvan•7/17/25, 5:16 PM

im just worried to hit 11 concurents for a second and get billed 2$ for nothing bascially x)

Kathy•7/17/25, 5:20 PM

valid concern - let me try to explain.
we're not trying to ding you if you go over to 11 for one day. we calculate the average over the month, not the max you ever hit during the month

i tried to explain using this example here. lmk if makes sense/rec on how to make more clear https://developers.cloudflare.com/browser-rendering/platform/pricing/#example-workers-bindings-pricing

How long should browser rendering take to take a screenshot? I set the timout at 10-15seconds and a lot of requests are failing.

soitchu•7/18/25, 7:02 PM

Hi! I had a quick question. We are looking into using browser rendering for a feature we are currently developing. One worry we have is that 10 concurrent browser sessions wouldn't be enough. I realize that we could fill out the form to increase that limit, but we aren't sure what the adoption of the feature would be like, so we don't currently have a concrete number. I just wanted to make sure we could increase that limit to something like 50-100, which is what I'm expecting our usage to be around.

Kathy•7/18/25, 10:31 PM

So with the new pricing announcement, we can go above 10 concurrent sessions but have to pay for each concurrent session above 10? I would need to run 20+ concurrently for 16-20 hours a month so not sure how that averages out with new pricing calcs

good question not sure if they check the avg of browsers ran or if you have days with 0 if that reduces that average

Silvan•7/19/25, 3:36 PM

i think its just total browsers used in a month devided by 30

I hope this message finds you well.

I am a Cloudflare user on the free plan, but unfortunately, I am currently unable to access my account due to being locked out by the two-factor authentication (2FA) process. I have lost access to my 2FA device and do not have backup codes available.

Because of this, I am stuck on the 2FA verification screen and cannot log in to request account recovery via the dashboard.

Hello!

I'm trying to render a page like https://www.censusdots.com/race/houston-tx-demographics that uses leaflet to render a web map. When I screenshot the page, I can see one layer of the map, but the tiles loaded by URLs like https://tiles.censusdots.com/file/race-tiles/10/240/422.png are missing.

This feels like a CORS issue. Is there something I need to be doing to allow the loading of the map? When I log network requests the tiles.censusdots.com requests 200

soitchu•7/21/25, 6:04 AM

I was testing out some pages, and saw some missing elements. Apparently, it's some weird interaction with mix-blend-mode and position sticky. Here is what it should look like vs what browser rendering captures:

regarding playwright-mcp, and to avoid significant changes in the upstream code, we keep a cloudflare folder where all workers logic is, and it also imports our @cloudflare/playwright dependency
