That's what I'm guessing might be happening

Hard@Work•4/25/25, 11:53 PM

Also might be some other kind of detection system, idk

Chaika•4/25/25, 11:55 PM

Looks like openai does use cf for their API as well

HHard@Work That's what I'm guessing *might* be happening

Nico•4/26/25, 1:11 AM

Just wondering about this still - With email workers, is it possible to do gmail style plus addressing? That is, once I bind my worker to an email "route", can I use the example@mydomain.com and example+foo@mydomain.com to send email to that worker?

Is it possible to control the Playwright instance of Browser Rendering API using prompts through the playwright-mcp server?

LordSilver•4/26/25, 7:04 AM

I would like inside a worker to write a few promtps "navigate to this site, click this, extract this info".

Hey guys, https://phantom.com (the crypto wallet) keeps sending phishing reports through various entities to my side-project hosted on https://phantom.ac (solely because the domain names match)

Here's a sample of what I have to deal with on a regular basis, where my DNS provider namecheap got a report due to some reporting a Nextcloud instance's login page as "phishing".

Issue is that due to these countless reports, CF now labels my pages deployment as "likely phishing" due to reports like these.

Elia•4/26/25, 1:11 PM

Any thing else I can do other than respond to CF Trust and Safety? People are paying for these tools and can't access them right now

James•4/26/25, 1:49 PM

Sadly all you can do is work with Trust and Safety, sorry

RRicky U Can someone help me about how to get Secrets Store working locally? https://disc...

fforres•4/26/25, 4:13 PM

+1 to this thread. I was checking that now. I imagine as a security measure you cannot access remotely created secrets on local. (makes sense)

If you work on your .dev.vars is great, but running a team, one of the benefits is centralized secret access for some variables.

Share some remote service tokens, or that same service address for example.
...but your local DB address/password is your own setup

Would love for some examples on a development flow that leverages local (.dev.vars) + secret store

fforres•4/26/25, 4:14 PM

We had a 1password CLI integration to load vars and dumping them in .dev.vars... but it's an overkill IMO

specially if we could do

secrets store

im currently running like 1 vite and 5 workers in a monorepo using turbo. i was wondering if i should instead use wrangler dev -c and run it all in 1 process. i have a feeling this will be the recommended way going forward :thinkies:

any opinions on that?

Bonadio•4/27/25, 8:08 PM

I created a simple template using TanStack Start with Cloudflare Workers, Drizzle, and D1 for anyone that want to try TanStack Start framework on CloudFlare Workers, works very well. Seems a good option for a NextJS alternative. I worked with Remix and TanStack Start seems an evolution.

Thanks for the repo. One suggestion: a seed script and mention in the readme how to populate the DB.

Mr. Technician•4/28/25, 12:23 AM

the only part of my infrastructure that I can't run on Cloudflare is my browsers since the existing browser rendering API doesn't support the stealth plugin

mr.niko.la•4/28/25, 3:49 AM

Regarding Cloudflare Workers AI, could someone form CF provide some sample code for implementation for the whisper model ? Despite Workers being reasonably priced and having a nice platform, their documentation is incomplete all I need is a sample code!!!! and I've spent considerable time trying to make it work.

This discord is it even official I am unable to ever get any devs to answer this for the past month

edit: whisper turbo sample code.

Hi everyone, I am working on an application, which allow my customers to setup custom domains.
Each organization could have different domains.
I plan to set up a wild card domain e.g: *.myapp.com -> mypages on Cloudflare
Is that possible to do that?

i can't fetch it from our DOs, even though we are ensuring that the DOs aren't in Hong Kong (unsupported by OpenAI)

AviOP•4/28/25, 7:10 PM

its like somehow cloudflare is looking at the incoming http request, keeping track of its geo info, and then automatically attaching that to my subrequests

AviOP•4/28/25, 7:10 PM

which i dont want, and frankly, seems like a privacy issue

AviOP•4/28/25, 7:11 PM

i just can't figure out which data that is... i'm looking at the http headers, and i'm not seeing which one is even being used to make this determination

Chaika•4/28/25, 7:13 PM

going to test something quick but I think the key here is that openai's api is behind Cloudflare

AviOP•4/28/25, 7:14 PM

yes, it does seem like something magical is happening because its a cf-to-cf request
