    This project provides a remote development platform that enables users to access a full-featured integrated development environment through a standard web browser. By decoupling the user interface from the server-side filesystem, it allows for persistent coding workspaces to be hosted on remote servers, virtual machines, or cloud-native infrastructure, ensuring a consistent development experience from any device. The platform distinguishes itself through a secure gateway architecture that manages traffic, authentication, and encryption at the edge. It utilizes persistent WebSocket connections

    Code-server gives you VS Code in the browser on a remote server, but it is designed for persistent workspaces rather than ephemeral, template-based sandboxes, so it is a neighbouring remote-dev platform rather than the isolated disposable environment you are looking for.
