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.

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

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.

Could you please assist me in recovering access to my account? I am happy to provide any necessary verification details to prove account ownership.

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:

hi team (@Rui Figueira ?) i notice https://github.com/cloudflare/playwright hasn't been released for a few months now, but lots of stuff has made it in. what's the plan around this?

i'm also seeing playwright-mcp is pointing to 1.53.0-alpha-1745357020000 and not the cloudflare fork.. how does that work?

Hey @dandoen ! We're working on upgrading playwright to a latest version. Actually, our main branch is already in sync with playwright 1.53.0, but are still adding a few more things before releasing

Rui Figueira•7/24/25, 6:47 PM

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

dandoen•7/24/25, 9:08 PM

@Kathy running my own browser DO from which i have my ai agent make tool calls, so can’t use playwright-mcp (violates the DOs i/o rules). hence need to do a few things similar to what playwright mcp dus just in my own service logic (like leveraging private apis from newer versions of playwright to get the accessibility tree for AI). in addition i couldn’t get a few cdp things to work on the 0.11 version, so hoping upgrade would help

hope that helps!

JJames agreed, can we get some attention on this one please @Kathy ?

dandoen•7/25/25, 1:32 PM

hello team, when using the cloudflare's playwright mcp from another worker i run into this:

Error: page.goto: Cannot perform I/O on behalf of a different Durable Object. I/O objects (such as streams, request/response bodies, and others) created in the context of one Durable Object cannot be accessed from a different Durable Object in the same isolate. This is a limitation of Cloudflare Workers which allows us to improve overall performance. (I/O type: Native)

note the original request to the mcp isn't made from a DO, so i'm not sure where this is coming from and what i can do to mitigate.

i guess not ideal (i’d love to separate and in my app users can bring their own mcp servers so it may be hosted on CF) .but i can give it a try.. any guidance on how to use the mcp lib without creating the server?
