You don’t need another subscription

Stop renting software.Own your own.

One subscription. The apps you need, built for you, and yours to keep: the code, the data and the insights.

How it worksWhat you own

Private beta. Invites go out by email.

Everyone pays rent on software they will never own.

A normal person now pays for notes, habits, invoices, recipes, a planner, a CRM. Five to fifteen small subscriptions, each a few dollars a month. In 2026 most of them added a second charge for their AI features. You pay more every year, and you own nothing at the end of it.

  • You pay per app

    Every tool bills you separately, and prices only move one way. The stack grows quietly.

  • Now you pay twice

    AI arrived as an upsell. The same app charges again for the feature that should have been inside it.

  • And it isn’t yours

    Your records sit on their servers. They pick the features, change the price, and read your usage.

How it works.

You never set anything up. No accounts to wire, no servers, no deploys, no backups to remember.

  1. Describe it, or clone it

    Say what you need in plain words, or pick an app from Explore and clone it. Cestra designs the screens, the database and the documents, writes the code and checks it, while you watch.

  2. Cestra builds the rest

    Cestra creates the database, the functions and the AI features your app needs. The AI features run on the tokens you already have in Cestra, so there is nothing extra to pay. Nothing to wire up, nothing to host.

  3. Open it from your link

    Publishing puts it live at a link that never changes. Add it to your home screen and it opens like any other app: no app store, no install, no updates to run. Share it with family or a team, and they sign in with their own Cestra account.

Stop paying for every app.

Ownership.

Every competitor says “your data is yours” in one line and then builds a business that depends on you staying. Cestra is designed so that leaving is possible, which is exactly why people trust it enough to put their real records in.

  • Your data

    One database per app, yours, exportable at any time. Not a shared table on someone else’s platform.

  • Your app

    The code and the documents belong to you. Cestra is the team that writes and maintains them for you.

  • Your people

    Everyone you invite signs in with one Cestra account. No extra subscription for them, no user base to administer.

  • Your insights

    Who used what, how often, what is slow, all reported to you. Never sold, never fed to an ad network.

One subscription.

A single monthly plan covers building apps and the AI that runs inside them, metered as an allowance per cycle. No charge per app you create or clone.

  • What you pay for

    Building, hosting, backups, updates, and the AI working inside every app you own. One line on the bill instead of twelve.

  • Where the cost sits

    Usage is visible and capped by design: a monthly allowance, per-app caps, and a daily limit per person. You see it before anyone is invited.

  • When you share an app

    You decide who pays for AI in it: you, the person using it, or you up to a point. Nobody is switched to their own tokens without choosing it.

Explore creations.

Explore is a shelf of apps people already made. Cloning one gives you the same design and code with your own empty database, so you are useful on day one instead of staring at a blank prompt.

  • Reading LogBooks, quotes and a streak.
  • Habit GridA year of habits on one page.
  • Invoice DeskClients, invoices and what is still unpaid.
  • Trip PlannerDays, places and who is bringing what.
  • Client CRMPeople, notes and the next follow-up.
  • Recipe BoxRecipes, with the scaling done for you.

Examples of the kind of apps the shelf will hold. Explore opens with the private beta.

The last software subscription anyone needs to buy.

Cestra is in private beta. Leave your email and we will send your invite when it is ready.
