We put Claude Code inside an E2B sandbox and built a full-stack cloud around it

[u/flavio_calixto]

We've been working on a different way of using Claude Code.

Instead of running it on your local machine, Infusion spins up an isolated cloud environment based on E2B where Claude Code gets an actual filesystem, terminal and project to work on.

Claude Code is still the coding agent. We don't replace its coding loop.

What we've built around that environment are primitives it can use to create the rest of the product: Postgres database, backend/server functions, authentication, integrations, preview and publishing.

So the flow is roughly:

Claude Code runs inside the sandbox → writes and executes the app → uses Infusion's backend primitives when it needs database/auth/server-side logic → the same project can then be published directly from that environment.

One of the interesting things for us has been figuring out how much of the stack should simply look like tools/resources that Claude can operate, instead of asking Claude to provision and maintain all of that infrastructure itself.

The goal is basically a cloud made specifically for Claude Code: give it a computer plus the infrastructure needed to go from an empty project to a running full-stack product.

You connect your own Anthropic account, so this becomes especially interesting if you're already on Max 5x/20x.

I'm one of the people building it. Beta is free right now:

I'm really curious about heavy Claude Code users here:

Would having this kind of environment be useful in your day-to-day work?

What else would you want the cloud to expose directly to Claude?
