Hey, early bird
Build a client portal for Acme. Every company should see only their own data, paid plans at $49 a month, and put it on a real URL.

I'll provision the infrastructure on Apper first, then build the interface against it.

Why AI stops listening?

Others pay for your AI.
So they prefer cheaper models.

Every request costs them money. A weaker model costs
them less - even when it builds you a worse app.

You've probably felt it

The AI stops understanding what you mean
One fix breaks two
other things
The design never quite
looks finished
The bigger the app gets,
the slower it goes
That's not you. That's a weaker model - and a credit meter that keeps running the longer it takes.
The part nobody owns

Other AI builders make the UI easy.
Then leave the backendto your AI.

Everything underneath - logins, permissions, custom-er data, payments - comes down to whatever your AI decides that day.

This is where data gets exposed, permissions fail, and a working demo becomes a developer's rebuild.

And you're not payingStop paying credits for any of it

Apper runs on your existing Claude Or ChatGPT subscription - you
keep the best models, and skip the AI-credit meter entirely.
Built in: profiles & permissions

AI-written rules make mistakes.
Apper adds a lockthey can't override.

Every AI builder — including Apper — uses database rules underneath. Apper adds a second, independent layer: readable profiles controlling every table, field, and operation. A bad rule can't open what a profile keeps shut.

APIconnectors & triggers

Your app talks to the tools you already use. New signup? Ping Slack, send a welcome email, update the sheet — automatically.
Other builders can't do this, because their backend has nothing to connect to. Every Apper app ships with connectors and its own API with real keys.

No connector found

The workaround, if you dare:

  1. Create a fake "robot" user in your database
  2. Use its password as a make-believe API key
  3. Write code to catch every event yourself
  4. Hope it doesn't leak access to everything
