Run any developer environment
Go beyond Docker images, leveraging Dev Containers to easily configure any type of setup, including servers, databases, and custom Docker configurations.
Build & scale seamlessly
Control sandbox dev environments with tools for terminal access, tasks, preview host, sessions, and more.
Robust snapshotting
Our tried-and-true memory snapshotting technology hibernates sandboxes and resumes them from a snapshot in 500 ms.
VM scaling
Get more CPU compute as you need it with hot-swappable VM sizes ranging from 2 to 64 vCPUs and 1 to 128 GB RAM.
Persistent storage
A git-versioned filesystem ensures your data remains accessible and secure.
"With Together Code Sandbox, we had an MVP running in a couple of hours, instead of waiting for months to see the result in a preview environment. Now, this is the core platform of HeroUI Chat that allows us to run the projects. Without it, we don't have a way to show users the result of the AI."
— Junior Garcia, Founder and CEO of HeroUI
