Would UDP services and anycast DNS be supported in the future e.g. to be able to run dnsdist or similar services.

They stated on the livestream they're considering TCP, but I suspect UDP is not coming soon since Workers themselves don't support UDP. All traffic going to Cloudflare Containers must be "proxied" through the Workers platform.

If my math is not wrong, running a single “standard” container during 1 month (non-stop) would cost ~55$.

This looks extremely expensive for anything other than a simple demo/toy project. I can’t think of a reason I’d use this for heavy services instead of using [anything else]. Maybe I’m not seeing the use-case?

I don't think you can calculate the cost of serverless compute this way. What containers do you have that run "non-stop"?

If the container doesn't run any workloads, it doesn't cost you anything. Most of the compute i pay for sit idle most of the time.

This is amazing pricing.

Say I want to deploy a service that is currently receiving 1rps at a constant rate, no upticks, no gaps. Wouldn’t that be the cost? If the answer is “yes”, then no, that is a terrible pricing.

Math is not wrong for the standard instance.

This is about using and abusing the _on-demand_ part.

The first example in the Getting started goes with sleepAfter = '10s'.

A 1 CPU + 2 GB of RAM + 50 GB ephemeral storage on Cloudflare Containers is $74.90.

The same on Fly Machines is $31.00 (performance-1x, varies by region). Fly Machines has the same sleeping functionality as Cloudflare.

Rivet Containers also has a similar price point of $29.40, but takes a different approach to sleeping (opts for optimizing coldstarts + autoscaling over snapshotting). (I work at Rivet)

I think Modal, which AFAIK has a similar feature set to Cloudflare Containers, also works out very favorably price wise compared to Cloudflare Containers.

And the gigantic AWS-tier bandwidth costs. This misses the mark by a lot. Classic example of pricing ruining a launch of decent technology.

It seems like always-on containers are not viable on this, so what's the point?

It’s likely aimed at bursty workloads. ie not one instance but a use case that fluctuates between 1 and 100 instances.

(I work at Cloudflare) We shipped a Containers 101 video today showing how to get up and running. YT: https://www.youtube.com/watch?v=oyOaxMY4eNo

We published an in-depth comparison between Cloudflare Containers, Fly Machines, and Rivet Containers: https://rivet.gg/blog/2025-06-24-cloudflare-containers-vs-ri...

So can we now host a whole website distributed in all regions on the edge with Cloudflare workers + containers ?

kentonv• 1 year ago

You've been able to do that for years, just using Workers (using Durable Objects for storage).

Egress is $25/TB unlike their other stuff. No thanks

Havoc2• 1 year ago

Sounds similar to what bunny is offering

Think CF lets you rate limit right?some form of it seems necessary with those egress rates
