It would be great if you could change the default URL (<YOUR_REGION>-<YOUR_PROJECT_ID>.

cloudfunctions.net) to a custom domain. I couldn't find a way to achieve this. It should be possible to set a CNAME that points to the default URL.

Hi. Yep.. we're aware of this. It's on our roadmap, but I'll leave the bug here so you can track when it's done

Its possible with firebase functions and a custom domain from what the docs say?

One way to solve this is to deploy a small proxy yourself with Caddyserver until this has a final solution.

I am using the Load Balancing and would really like to see that you can use a cloud functions as a backend, not only buckets and instance groups.

Are there any updates from Google about this? It'd be great to know more about the timeline.

+1 for I'd like to see an update with a timeline, especially as this can be done in Firebase functions.

I'd like to see a CNAME approach to custom domains for Cloud Functions.

Firebase Hosting currently supports rewrites that point to a Function -- effectively giving us pretty URLs for Functions -- but it is slower by a magnitude of nearly 2x, and it also increases data transfer, probably because of Firebase's additional response headers.

I've attached a screenshot of response size and times from calling the same function directly (via

cloudfunctions.net) and then from Firebase Hosting rewrite.

My use case:
I have Cloud Functions REST APIs that interact with Firestore; without the ability to use my own domain to access the REST APIs is really a show-stopper. And as the above user mentioned, Firebase's performance is just not acceptable in a production environment.

Un-assigning this. We're actively working on a solution but don't have timelines to share right now.

ji...@platforma.one <ji...@platforma.one> #16Jun 19, 2019 06:28AM

Finally a solution!

Hide Functions behind Cloud Endpoints, which uses Cloud Run as API gateway and you can set a custom domain there.

Google Cloud Endpoints on Cloud Functions (

https://cloud.google.com/endpoints/docs/openapi/get-started-cloud-functions)
Cloud Run custom Domain (

https://cloud.google.com/run/docs/mapping-custom-domains)

Heads up that ^ is a beta solution, not yet advised for production use.

We're using Cloudflare Workers as a reverse proxy over Cloud Functions for now:

https://stackoverflow.com/a/66815871

ya...@gmail.com <ya...@gmail.com> #21Mar 26, 2021 12:32PM

#20 - that is only acceptable for "public" functions without authentication (except through an API key) since Cloudfare is outside of GCP.

Next to Cloud Endpoints, there is API Gateway now which seems to be a better fit.

Googlers, is that the final word for a CNAME override, using API Gateway ? If so, case closed I guess but adding a service just for that is unnecessary overhead. Maybe it is a strategy to favor/migrate external http functions to Cloud Run - which supports custom domain.

ko...@gmail.com <ko...@gmail.com> #22Mar 26, 2021 12:40PM

#21 - Cloudflare Workers work great with private cloud functions thanks to its "crypto" API and GCF service accounts. It still remains the best option I believe if you need to do more sophisticated stuff at CDN edge locations - render a single page app (SSR), inject hydrated API response, configured CSRF protection, and advanced caching strategies.

But for simpler use cases, it would still be great to have custom domain names supported natively (without Firebase, Cloud Run, or Cloud CDN) - via a CNAME.

Cloud functions will only open to more users/usages if custom domains are supported. I cannot understand why this is still not implemented after so many years.

ya...@gmail.com <ya...@gmail.com> #40Jul 3, 2022 12:34PM

This has been supported with gen2 functions for a few months. Gen2 relies in Cloud Run where you can link a custom domain to the endpoint. Agreed a Googler could have said so earlier and close the issue.

Hello Google Team, Any updates on this feature request?

de...@simpleclub.com <de...@simpleclub.com> #45Dec 6, 2022 08:25PM

One solution could be to upgrade your function to v2 and attach the domain to your Cloud Run instance: https://cloud.google.com/run/docs/mapping-custom-domains

ch...@chris-reilly.com <ch...@chris-reilly.com> #46Dec 6, 2022 09:26PM

That (Cloud Functions v2) is the correct answer and candidly I feel that this thread should be closed now. I highly doubt there will be future feature dev on CF 1, and this seems like it would be low on the list if something were to be shipped. Hopefully Cloud Run / Cloud Functions can meet that requirement for custom domains going forward. If not, a micro nginx server or load balancer can easily proxy requests from any domain you like - but neither scale to zero.
