Does Workers for Platforms work with Durable Objects? I didn't see that mentioned in the documentation. Thanks!

demotime•6/6/25, 7:47 AM

does anyone know whether we can run user-workers with a regular http url/api, or if it's ONLY via. the dynamic dispatch worker?

demotime•6/6/25, 8:06 AM

it's very awkward running locally, because the flow goes:

edit user code & run

but the APIs to create/edit users-workers seem to not have a local equivalent. so there's no (simple) way to save and test a change, which is pretty fundamental WFP interaction? Also makes it very hard to test the combined code when we add platform stuff to user-stuff

if there's a way to just run the production worker from local that would be one solution I think. interested how anyone else gets around this or what I'm missing

i guess i could deploy a proxy dispatch worker, then abstract a proxyOrRun method, if env.proxyDispatchUrl is set go via. that. anyone happen to know any best practice or workflow which would let us deploy and test scripts locally (local env, local dispatch worker, scripts either locally emulated or production ones)

darkpool•6/6/25, 1:54 PM

maybe im not understanding but in my case I simulate local dev with treating the user code as a module and importing it before wrapping my own platform code around it to "hydrate" it. Also you can run dispatch locally with --remote to test deployed user workers

Rafflesia•6/6/25, 5:18 PM

In the call accounts/{account_id}/workers/ dispatch/namespaces/ {dispatch_namespace}/scripts/ {script_name}

Is there a way to also bind the domain? Or must that be a seperate call

Rafflesia•6/6/25, 5:18 PM

~~Currently I can create the worker programmatically but I cannot figure out how to bind a domain~~
Resolved by just properly using a dispatch worker

Rafflesia•6/6/25, 5:18 PM

And it doesn't even have a default workers.dev domain

Rafflesia•6/6/25, 6:35 PM

if not, is there a "workers for platforms" equivilant of https://developers.cloudflare.com/api/resources/workers/subresources/domains/methods/update/

for included monthly, when it says 1000 scripts included, is that 1000 new scripts per month or is that 1000 scripts total

Is there a frequency limit if workers are used to operate r2 or vector?

Zuch•6/12/25, 2:50 PM

Everyone, I'm going bankrupt. My bill last month included a charge of $2,581.76 for Workers for Platform Scripts. The bill shows a quantity of 129,088 workers, a unit price of $0.02, and a total price of $2,581.76.

However, when I look at the console, I only have 4,628 workers. So, does anyone know how the 129,088 is calculated?

Zuch•6/12/25, 3:57 PM

Also, the documentation does not indicate whether worker scripts are a one-time payment or a monthly payment.

Walshy•6/12/25, 4:01 PM

We're looking into it, thank you

As for the frequency, yeah it'd be monthly, we'd encourage making sure to cleanup any unused scripts to make sure you're only billed for what you're actively using

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

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?

Successful-Arm-3762•6/21/25, 10:56 PM

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

Specifically the "namespaces" limit.
