Cua Cloud (Fleets) has ended

Cua Cloud and Cua Fleets stopped on 16 October 2026. What changed, what happened to your data, and where to run sandboxes now.

Cua Cloud, including Cua Fleets (pools, claims, warm replicas and the Terraform provider), stopped on Friday 16 October 2026. Remaining customer data was deleted then. The Fleets pages that used to be here have been removed.

What still works#

The same SDK calls, images and cua CLI commands run anywhere else:

Where	How	Guide
This machine	`Sandbox.create(...)` (the default), `cua sb create`	Set up local runtimes
Your own AWS, Google Cloud or Modal account	`on="aws"`, `on="gcp"`, `on="modal"`; `--on aws` in the CLI	Use your own cloud
A machine you run, shared with your team and agents	Cua Spaces	Cua Spaces

In your code#

on="cloud", local=False, --on cloud, Cua.fleet() and cua fleet are deprecated and no longer reach a service. They are removed in cua 0.5.0.
Replace on="cloud" with a local runtime or your own cloud. Sidecars, services, secrets and images work the same way there: Sidecars, Services, Secrets, Images.
Fleet pool names, claim TTLs and warm-replica settings have no replacement. Your own cloud gives each sandbox a time limit and cleans up after it (Time limits and cleanup).
