# Cloudflare Containers and Sandboxes are finally GA!

Hey everyone, it's me, Shii-chan! Today I've got a "it's finally the official release!" kind of news that folks who've been waiting will love.

## What was announced?

On the Cloudflare Changelog, **Containers** and **Sandboxes** were announced as generally available (GA). Containers let you run CLI tools that need a full Linux environment, apps in many languages, and heavier workloads right next to your Workers. It's on the Workers Paid plan.

## The story so far

Until now, Containers had been steadily stacking up features since launch. Going GA means it's no longer "try it out and stop there" — it's Cloudflare's sign-off that you can rely on it in production. It reached the official release with all the post-launch improvements baked in.

## What changes

The big deal is that you can now more seriously pick it as a base for running containers. Thanks to the higher resource limits added before GA, it can handle **thousands of concurrent containers**, and billing is an Active-CPU model that only charges for the CPU cycles you consume. Not paying for idle time is great news if you want to keep containers around for a while.

## Dive Deep

Here are the improvements that landed on the [Containers](https://developers.cloudflare.com/containers/) side after launch:

- [Active-CPU pricing](https://developers.cloudflare.com/changelog/post/2025-11-21-new-cpu-pricing/), so you only pay for the CPU you consume
- [Easy connections](https://developers.cloudflare.com/changelog/post/2026-03-26-outbound-workers/) to Workers and other bindings via hostnames
- Use existing images and registries with [Docker Hub](https://developers.cloudflare.com/changelog/post/2026-03-24-docker-hub-images/)
- [SSH access](https://developers.cloudflare.com/changelog/post/2026-03-12-ssh-support/) for debugging

And [Sandboxes](https://developers.cloudflare.com/sandbox/) (the Sandbox SDK) gained a bunch too: live preview URLs to check long-lived services, persistent code interpreters for Python, JavaScript, and TypeScript, browser-based [interactive PTY terminals](https://developers.cloudflare.com/changelog/post/2026-02-09-pty-terminal-support/), [backup and restore APIs](https://developers.cloudflare.com/changelog/post/2026-02-23-sandbox-backup-restore-api/) for snapshotting your workspace, and even [real-time filesystem watching](https://developers.cloudflare.com/changelog/post/2026-03-03-sandbox-watch-file-events/) that reacts instantly to file changes. Handy when you want to embed a whole code-execution environment.

## Wrap-up

- Cloudflare Containers and Sandboxes are now GA (generally available)
- It's on the Workers Paid plan; the highlights are thousands of concurrent containers and Active-CPU pricing
- Docker Hub integration, SSH, preview URLs, PTY terminals, backup/restore, and more — all the post-launch improvements are on board

If you want to run a full Linux environment near the edge, or safely let an AI agent execute code, this is your cue to start thinking about production!
