The questions that decide it.

No. Designing, Run and Debug are free — in the beta and for ever. You can build a whole application, start it, use it and step through it without a key; the Run loop is the entire evaluation. What a licence buys is turning that project into an .app, test build and release build alike — in the beta exactly as after 1.0. Schools need nothing from us: Run and Debug are the entire classroom loop.

Every application you already shipped keeps running — for ever, on any number of Macs, and it never checks a licence. The IDE keeps designing, running and debugging with no key. The one thing that waits until you renew is producing a new build: you rent the workshop, never the things you make in it. Renew and building comes straight back — no read-only mode, nothing crippled, nothing taken away.

One thing every build does carry, whatever the subscription is doing: an imprint in the About window — which Neuridion made it, the name on the licence, and a short code derived from it. It is a note about where the application came from, never a check: nothing reads it back, and removing it would change nothing about how the application runs. See How licensing works.

For a release build, yes: it is signed and notarized with your own Developer ID, which needs Apple's Developer Program — about 99 € a year, paid to Apple, not to us. A test build signs ad-hoc and needs no Apple account; it runs on your own Mac. Designing, Run and Debug need neither Apple nor us.

For a working application with lists, forms, search, printing and backups: none. You start writing when you have a rule of your own — “this invoice may not be changed once it is booked”, “fill the town from the postcode”. Those are a handful of lines each, in JavaScript, with the schema in front of you as you type.

Yes. One .app, no runtime to install, no framework the customer has to find. It is our precompiled shell plus your project as an encrypted payload — which is also why building is instant.

No. The beta IDE keeps designing, running and debugging for as long as you like — there is no clock in it (removed 22 August 2026, together with free beta builds: building an .app is what needs the subscription). When 1.0 arrives, it is simply the better version to download. Applications you shipped are unaffected — for ever. Nothing Neuridion builds contains an expiry.

Not guaranteed. Until 1.0 the project format can still change and there are deliberately no compatibility shims — a clean format matters more right now than a smooth path for a beta. Take it to learn with and to have a say in, not for the data your business depends on.

No, and not planned. Mac only is what lets us use the newest of everything with no compatibility baggage — it is a decision, not a gap. A browser front end is being studied for much later.

Only to ship. Designing, Run and Debug need nothing, and neither does a test build beyond a Neuridion licence. A signed and notarised application needs your own Developer ID — Apple's rule, not ours, and it is your name that belongs on your application anyway.
