Hi Walshy, how is it going?

ZZuch Hi Walshy, how is it going?

Walshy•6/13/25, 3:00 PM

Should have a reply to your ticket shortly, working on getting you sorted :)

Is there an API to grab realtime logs for workers?

Rafflesia•6/16/25, 9:25 PM

Wow! This seems quite concerning I hope CF has a good answer for this. I've been wondering if it's the amount of workers that exist in a month or how workers that exist for one day and are deleted the next are billed

WWalshy Should have a reply to your ticket shortly, working on getting you sorted :)

there's still no news.

ZuchOP•6/17/25, 7:59 AM

Yes, CF does not specify how to calculate the number of worker scripts.

laurynas•6/17/25, 2:32 PM

are there plans for a better local dev experience? Would love to be able to test some flows without needing a deploy

This should work? https://developers.cloudflare.com/api/resources/workers/subresources/scripts/subresources/tail/

Cloudflare API | Workers › Scripts › Tail

I'm not sure if I can just put the dispatch namespace in the URL and if it will just work

RRafflesia but I dont see that for workers for platforms

Hard@Work•6/17/25, 9:45 PM

If you initiate a tail for your Dispatch Worker, it should show logs for WfP Scripts

Rafflesia•6/17/25, 9:45 PM

alright, I was mostly just checking that I wouldn't need to make a tail worker instead

Successful-Arm-3762•6/21/25, 12:59 AM

Hi everyone,

I'm trying to understand the binding capabilities in Workers for Platforms user workers (not the dispatch worker). Specifically:

Service Bindings: Can user workers have service bindings configured when they're uploaded to a dispatch namespace? The docs mention that service bindings "don't work in the Workers for Platforms model because User Workers are uploaded ad hoc" but it's not entirely clear if this means user workers can't have ANY service bindings or is this forbidding the use of Service Bindings as a replacement for the WfP dispatch mechanism itself?

I found this in the docs: https://developers.cloudflare.com/workers/runtime-apis/bindings/service-bindings/#workers-for-platforms but it's not completely clear on the scope of the limitation.

Service binding documentation says that binded service worker must be deployed before the one that declares the binding. So if I have the service worker deployed would they be accessible from the namespace/user-workers called by the dispatch worker? https://developers.cloudflare.com/workers/runtime-apis/bindings/service-bindings/#deployment

I assume that workers for platforms keep talking about customer user code and since it is "namespace" bound, they might not be available, but this programmable pattern tells me other common resources are available:

https://developers.cloudflare.com/reference-architecture/diagrams/serverless/programmable-platforms/#resource-isolation-model

Workflows: Are Workflow bindings available in user workers? I couldn't find specific documentation about this.
request.cf: If the cf object always unavailable in WfP?

Does anyone have any definitive info on this? Thanks!

They can have service bindings but they must bind to non-wfp-workers

Workers and WfP is currently incompatible

It's available

Successful-Arm-3762•6/21/25, 4:47 PM

Thanks Walshy!
Just a small follow up: workflow will still be available on the non-wfp-workers and the dispatch worker?

Walshy•6/21/25, 4:50 PM

Yes you could use it on the dispatcher

rob•6/21/25, 6:01 PM

does thsat new worker upload on the SDK released work for WFP?

WWalshy Yes you could use it on the dispatcher

Successful-Arm-3762•6/21/25, 10:56 PM

thanks mate!

Successful-Arm-3762•6/23/25, 3:50 AM

is it possible to deploy a shared/common worker, and use WfP to create user workers using that script with different bindings? and any updates/new deployments made to that common worker picked up by the user workers?

Successful-Arm-3762•6/23/25, 4:13 AM

I think this is not possible. Correct me if I'm wrong.

Does anyone else have better patterns for creating workers with tenant specific bindings?

Successful-Arm-3762•6/23/25, 4:25 AM

On another note: I think if this is just made available, it would be a great way to deploy custom binded workers that update on just one wrangler deploy. This solves the dynamic D1 bindings not available problem.

The model would stay the same as depicted here in the docs: https://developers.cloudflare.com/reference-architecture/diagrams/serverless/programmable-platforms/#resource-isolation-model

Programmable Platforms

A programmable platform allows customers to customize a product by writing code. Unlike traditional SaaS with fixed features, it enables users to extend functionality, deploy backend logic, and build full-stack experiences—all within the platform’s infrastructure.

Yes, maximum 1000 per docs here: https://developers.cloudflare.com/kv/platform/limits/

Isaac McFadyen•6/24/25, 8:21 PM

Specifically the "namespaces" limit.

Isaac McFadyen•6/24/25, 8:21 PM

Ah sorry - missed that this was for WfP. Not sure if the limit is the same or not for KV.

darkpool•6/27/25, 7:54 PM

gotcha. are you using multi part form upload?

darkpool•6/27/25, 8:02 PM

hmm not sure sorry. I am just using api to upload user workers but dont see why it wouldn't work since wrangler is using it behind the scenes.

Rafflesia•7/6/25, 6:12 PM

is there a way to have a tail worker for a whole dispatch namespace?

Walshy•7/6/25, 6:45 PM

You can tail the dispatch worker and get logs for all user workers

Rafflesia•7/6/25, 6:45 PM

oh cool

Rafflesia•7/6/25, 6:46 PM

Tailing is not enabled for your account. Please see our docs for more information: https://developers.cloudflare.com/workers/observability/logs/tail-workers/

Tailing is not enabled for your account. Please see our docs for more information: https://developers.cloudflare.com/workers/observability/logs/tail-workers/

I get this when I try and add a tail consumer to a worker in a dispatch namespace though and I dont really see a way to really enable them, should I just add it to the dispatch worker instead in that case?

Rafflesia•7/6/25, 6:46 PM

or is there a specific procedure I'm missing

Walshy•7/6/25, 6:50 PM

You should have tailing, do you have workers paid?

Rafflesia•7/6/25, 6:50 PM

just checked, we pay for workers for platforms but the dispatch worker is still workers free (since we're still just trialing it)

Walshy•7/6/25, 6:51 PM

Ah, that'll be why unfortunately

Walshy•7/6/25, 6:51 PM

We should probably make tailing available too for WfP sub though, will chat with the PM on Monday.

Rafflesia•7/6/25, 6:52 PM

alright

KernelDeimos•7/7/25, 1:31 AM

yeah extra fee for that is not an issue but just inconvenient, it seems a little silly IMO

Village (Josef)•7/8/25, 9:15 PM

Hey, is there any way to set up Email Routing for Workers for Platforms/Cloudflare for SaaS? I'm essentially hoping to be able to process any emails sent through client domains (obviously if they've configured it to do so) through an Email Worker.

Hi Walshy, how is it going?
