Can you use proxies ?

TThibault I have taken 226 screenshots today Does it mean I wasted $22.6 😭

they are working on keeping the session alive for longer. I saw a github branch https://github.com/cloudflare/puppeteer/commits/add_keep_alive_option by @sc

but best way is to just use durable objects I think. You can use the same session for parallel requests.

I've filed https://github.com/cloudflare/puppeteer/issues/36 but it would be really good to see some upstream updates for this now that Browser Rendering has hit GA

do we still need to request access here?

You don't. Browser Rendering is now available on all Workers paid plans

ahhhhh think i missed that in the docs

How can i find the browsers overview in the dashboard?

.Zero•4/7/24, 8:08 PM

I have gone through all sections and i cannot see where i can find that? I had beta access before but now i just cannot find it

The dashboard UI isn't enabled yet

Yacine Hmito•4/8/24, 11:08 PM

From what I remember of sifting through the git log, the puppeteer version is tied to the Chrome version, and this is the version of puppeteer that matches the version of Chrome currently running on the Browser Rendering API. But I may be mistaken.

James•4/8/24, 11:09 PM

Quite possible. It appears to be Chrome 110 when I last looked, but some kind of strategy and commitment to updates would be good.

cj•4/9/24, 4:39 AM

Is there a separate pricing for the browser rendering api? I can't find anything on how much it will cost

cj•4/9/24, 4:46 AM

Oh. It's free untill they make the pricing public.

While you won’t be billed for the Browser Rendering API yet, we want to be transparent with you about costs you start building

But from their Running Serverless Puppeteer with Workers and Durable ObjectsRunning Serverless Puppeteer with Workers and Durable Objects blog post back from 09/28/2023 it will cost $0.10/browser session

Oom Why is it still showing beta in docs?

It says betabeta in the dashboard too. IDK

Can I start using browser-rendering-api in a production app yet?

cj•4/9/24, 6:26 AM

I'm trying to run the get started screenshotscreenshot code - link

But I get the error

Cannot read properties of undefined (reading 'fetch')

Is there a working example I can try running? Cloudflare should fix their examples on the docs page.

You need a cloudflare workers paid account to get access to the browser rendering API. If you have that, then just visit the docs page to get started. FYI, it didn't "just work" for me.

Browser Rendering is now available to all customers with a paid Workers plan. Each account is limited to running two new browsers per minute and two concurrent browsers at no cost during this period. Check our developers page to get started.

How would pricing evolve for long running browser sessions?

For example, an automated testing browser session + queue. I will only run a single browser session and use a queue to manage my tasks. But in this case a browser session can exist for multiple minutes.

Is it currently possible to run a long running browser session on cf api?

cj•4/9/24, 7:44 AM

Pricing for existing headless browser APIs like browserless.io depend on unitsunits per months - where one unit = 30 seconds

Pricing – Browserless

The headless browser platform that scales your automation.

Advany•4/9/24, 9:48 AM

With do's, if you manage it properly, you should be able to use 2 sessions to get as many units as are on the start plan

cj•4/9/24, 11:45 AM

(180,000 units * 30 seconds)/ 60 seconds / 60 minutes / 24 hours = 62.5 days
So two browser sessions + a lot of DO million seconds.

cj•4/9/24, 11:50 AM

Quick math to run a browser session for a whole month:

Cost Estimate for 1 Month

Browser Sessions: 1 session for the whole month = $0 or $0.1 (if you exceed free tier)

Durable Objects Costs:
RequestsRequests: Alarm DO every 10 seconds = 259,200 pings / month. The first 1 million pings are free = $0 or $0.03888 (if you exceed free tier) - 259,200 requests / 1,000,000 = 0.2592 million requests * $0.15 = $0.03888
TimeTime: 30 days * 24 hours/day * 3600 seconds/hour = 2,592,000 seconds
Compute DurationCompute Duration: The DO is active for 2,592,000 seconds. Converting to GB-seconds: 2,592,000 seconds * 128 MB / 1 GB = 331,776 GB-s. The first 400,000 GB-s are free = $0 or $4.1472 (if you exceed free tier) - 2,592,000 seconds * 128 MB / 1 GB => 331,776 GB-seconds / 1,000,000 => 0.331776 million GB-seconds * $12.50 = $4.1472

Estimated Total for 1 Month:

$5 (workers paid plan)
$4.28608 (if you exceed free tier)

cj•4/9/24, 11:50 AM

vs $200 with browserless.io

cj•4/9/24, 11:59 AM

But concurrency is the key here. I don't have a usecase where I need to run a single session for a month - but instead use cloudflare's infra to many handle requests for a product (eg screenshot api). So only after cloudflare let us run 500 concurrent sessions will it be really useful.

Advany•4/9/24, 2:24 PM

you know that you can run current requests on 1 do / 1 browser session? I am easily running 25ish current requests on one browser session. It just opens multiple pages and closes them after its done

cj•4/9/24, 2:54 PM

Are there any limitation on the number of tabs opened? Memory limit or something?

I know there is none stated in the limits page but did you face any issue while in production?

rob•4/9/24, 5:02 PM

Im curious on that also

Ccj You are already using it in production?

Advany•4/9/24, 7:43 PM

I had a hard time crashing it. I set the limit to 25 for myself to be save.

Also using it in production.

I did test it once with 100 to 1000 current pages. Crashed around 200ish.

You get 500 included.
