This is a new service (in "alpha" status) for creating Linux virtual machines, which can do whatever you like. here's their announcement post.

It's free for now, but they plan to charge $20 a month. The interesting bit is that they automatically install a coding agent for you in the VM. I'm not sure there's anything all that groundbreaking here, but it seems nicely done and I was curious enough to actually try vibe-coding something.

The UI is rather minimal. Signing up is easy; it just requires an email. You can create a passkey or continue to sign in using email.

Once you're signed in, you can create a VM. There is a "description" field where you can optionally describe what you want your VM to do. The coding agent automatically starts up and starts building whatever you asked for.

So I asked it this:

Make a minimal website where I can share links, listed in reverse chronological order. Each link has a URL, title, and one-line summary. When I paste in a link, automatically download the page. Automatically choose the title and summary using an LLM.

And so it wrote me a little website in Go, using sqlite for the database. I can talk to the coding agent in a web browser by connecting to port 9999.

It didn't get it right the first time. I had to ask for some corrections. Also, the part where it calls out to an LLM to choose a description didn't work, so I told it to take that out and put in an edit button. But a few minutes later, I had a dumb little link-sharing website at https://skybrian-links.exe.xyz/.

There are no tests and it's just editing the live site. The initial website was committed to git (locally, in the VM), but any changes you ask for won't be committed unless you ask. I haven't bothered to upload it to github.

To make it public for everyone else to see, I had to ssh to exe.dev and run 'share set-public skybrian-links'. The coding agent can't do this, but it can tell you what to do.

Here's a post by one of the developers about how they asked it to create a shopping list app while in the grocery store.
