Nothing touches your computer
A cloud sandbox is an isolated, disposable machine where agents install dependencies, run commands and start dev servers.
Jennefer Cloud Coming soon
Break things. Not your laptop.
Give your agent team an isolated, disposable machine in the cloud. They install, run and preview there while your computer stays clean.
Sandboxes are my favorite kind of box. Nothing gets out.
See it running.
Real screens from Jennefer Cloud, on one RTX 4070 with a local model.
A clean machine every time.
Start from a template or a repo
Next.js, Vite and React, Django, FastAPI and more, or import a public Git repository from GitHub, GitLab, Bitbucket or Codeberg.
Same team, same chat
Files, a shell, a live preview and the team chat you already know, all in Cloud mode.
Bring your coding CLIs
On Cloud Pro and Team: Claude Code, Codex, Gemini CLI, GitHub Copilot CLI and opencode with your own keys, written only inside that sandbox.
Preview on every screen
Switch the live preview between Desktop, Tablet (820 px) and Mobile (390 px).
Pause when you are done
Resume or pause any sandbox and keep an eye on the Cloud hours you have left.
Build from your phone
In Jennefer Mobile, describe a change and one agent builds it in your sandbox with your own endpoint, even with your computer off. Your provider bills the model; the sandbox uses Cloud hours.

1 Cloud hour = 1 hour of a Basic sandbox (2 vCPU, 2 GB RAM). Larger sandboxes use more Cloud hours per hour. There is no free Cloud tier; without a plan your agents keep working in your projects on your computer, at no cost.
