New Two teams run production workloads on a single binary

Your next backend, built without hiring.

Your coding agent builds the backend from inside Cursor or Claude Code. Auth, schema, row-level permissions, storage, deployed and running before kickoff. Your engineers stay on the work clients pay a premium for.

Two teams moved their live apps over from Supabase, including a local clinic’s 8 GB instance, live again in under an hour without changing a line of their code.

Prefer to just describe it?

Not running an agency? This is still for you.

Tell us what you want built in plain English, no editor, no MCP, nothing to install. We build the app and everything behind it.

Your ideas stay private. We never train on your data.

Not sure where to start?

I'm not technical

You want a real app that works, explained in plain English, no jargon, no engineering hire.

I'm a developer

You want the wire-compatibility details, the config file, the binary, and the MCP setup.

What you’re actually getting

The hard part isn’t building an app. It’s everything behind it.

Every app has an engine room behind it, where your users’ accounts, data and files live, and who’s allowed to see what. AI can write a good-looking app in an afternoon; that engine room is what decides whether it survives real customers, so it’s the part we build.

01

You shouldn't need to hire an infrastructure team

Most tools leave you to run everything behind the app yourself, normally a hire, or three, the moment cost or a security review forces the issue.

How we solve it

instancez is one program, the same thing runs whether we host it for you or you run it yourself, in one command, not a new hire.

02

“You can leave anytime” only counts once somebody has

Every tool promises you're not locked in. That promise is only worth something once a real company has actually left and stayed open for business.

How we solve it

Your app talks to us the same way it talked to Supabase, so moving over means changing an address, and moving away later is just as cheap.

Outcome

A local clinic's 8 GB Supabase instance was live again in under an hour, with zero changes to their application code.

03

You should be able to see what the AI built

When AI builds your app by clicking around a control panel, nobody, not you, not a developer you hire later, can check its work.

How we solve it

Everything the AI builds is written down in plain, readable form, and every change goes to a private preview first, so nothing reaches your users until you've tried it yourself.

What you get

  • A real database
  • Rules about who can see what, enforced on every request
  • Sign-in that already works
  • Somewhere to put files
  • Custom logic when you need it
  • Runs anywhere you want it

Why the AI gets it right

We built this to be the thing AI is already best at writing.

AI models learn from the code that already exists in the world. We deliberately built instancez to work the same way as the most widely used tool of its kind, so the AI is writing something it has seen millions of times rather than guessing at something new.

That’s the difference between an app that works on the first try and one that looks finished but quietly breaks. It also gets better on its own, as models read more of that code, they get better at ours, without us changing anything.

Want us to host the app too?

Already had an app built somewhere else? Send us the code and we’ll run it for you. You get a private link to try it first, and you publish when it looks right.

And when it needs somewhere to keep accounts, data or files, that’s already here.

Nothing goes live until you say so

However you start, you get a private version to click around and test first. It goes live for real customers when you say it’s ready, not when the AI decides it’s finished.

Questions worth asking

Especially before you build something real on top of us.

Do I need to be technical to use this?

No. Describe what you want in plain English and we build it, then give you a private link to click around and try before anything goes live.

What we won’t do is leave you stranded later. Everything we build is written down in a readable form, so the day you hire a developer or bring on a technical cofounder, they can pick it up and keep going rather than starting over.

Do I own what gets built?

Yes. If you cancel, you walk away with a working app and everything needed to keep running it, not a read-only copy or an export you can’t do anything with.

Nothing about your app is locked in a format only we can open. It’s all ordinary files you can hand to any developer.

Specifically: your schema, security policies and functions are plain YAML and JavaScript you can commit to your own repository, and the runtime they execute on is open source.

Can I see changes before my customers do?

Always. Every change goes to a private version first, a real, working copy of your app that only you can reach. You click around, check it behaves, and publish when you’re happy. Nothing goes live because the AI decided it was finished.

And because the whole configuration is a file under version control, the previous working state is always something you can read, diff and re-apply.

What happens to my app if instancez goes away?

It keeps running. Everything your app needs to work is open source and yours, so the worst case is that you or a developer you hire runs it on your own server instead of ours.

We’d rather answer that honestly now than have you find out the hard way. It’s also why we made leaving cheap on purpose, an insurance policy you can inspect before you trust us with anything.

Where does my data live, and do you train on it?

We never train on your data or your prompts. Hosted projects run on dedicated Postgres instances with encryption in transit and at rest. On Enterprise you can deploy into your own cloud account and bring your own LLM provider, so nothing leaves your perimeter.

Still deciding? Talk to a cofounder, you will get an actual engineer, not a sales rep.
