For a while now something about the whole “AI writes your code” wave has bugged me.
Most of these tools write code they never actually run. They hand you a snippet, act confident about it, and it’s on you to paste it somewhere, host it, wire it up, and find out later that it doesn’t quite work. The building part looks magical in the demo. The part where you have to actually run the thing, the servers, the SSL, the glue, that’s the part that quietly kills most good ideas, and it’s the part nobody shows.
The other option isn’t much better. You can just let an AI agent loose on your laptop. But an AI with the safety off can wipe the wrong file or leak a password while you look away. So you end up hovering over its shoulder, which rather defeats the point.
I kept thinking there should be a third option.. and after hitting that wall one too many times, I started building it.
So, what is it?
ctx7 is software you install and run yourself, on your own hardware. Your laptop, or a cheap €5/month server. It gives your AI a real, sealed-off machine to build on. Not a chat window, and not my cloud.
The loop is the part I’m proud of. Your AI builds inside a sealed container, opens each app it makes in a real browser to see what actually happens, and fixes what breaks. You watch over a private link and step in when you want. Because it’s walled off from everything else, you can hand it real power, walk away for a few hours, and trust it not to touch anything you didn’t give it.
Every app it builds gets its own private HTTPS link. Nothing goes public unless you say so. And your code stays exactly what it always was: a plain git repo on plain Docker. I add the networking, the SSL and the VPN. I never hold your project. One command packs the whole thing up, code and database and all, and it runs on any Docker host. That’s your exit, built in from day one.
Who’s it for?
Honestly, people who like to build things.
- Developers and founders who want their AI on a real machine that runs and tests its own work, with their own AI agent.
- Technical creatives who outgrew no-code but dread DevOps. Start on the managed option and I run the boring parts, you just describe and build.
- Agencies and studios who want to build with AI and then hand the client the actual keys. The app, the code, the server. Nothing to be locked into.
Where it’s at
It’s early. I’m opening it up in waves rather than flipping a big switch, partly so I can keep hardening the thing, partly because I want to do this properly.
If any of the above sounds like you, or if you’ve felt that same itch.. you can grab a spot on the list at ctx7.dev.
More soon!
