Free to build with.
A license is for shipping.
Designing, Run and Debug cost nothing and always will — that is the loop you actually work in, all day, on any number of Macs. What a license buys is turning a project into an application. And whatever you build costs your customers nothing.
What is free, and stays free
This is not a trial that runs out. It is the part of Neuridion that never needs a key, in any version, for anybody.
| What you do | Beta (today) | From 1.0 |
|---|---|---|
| Draw schemas, design forms, lists and reports | Free | Free |
| Run — start your project and use it | Free | Free |
| Debug — breakpoints, stepping, the query log | Free | Free |
| Open, take apart and keep the example projects | Free | Free |
Test build — an unsigned .app on this Mac | License | License |
| Release build — signed, notarised, for somebody else | License | License |
One thing comes from Apple, not from us: a release build is signed and notarized with your own Developer ID, which needs Apple's Developer Program (about 99 € a year, paid to Apple). A test build signs ad-hoc and needs no Apple account — it runs on your own Mac.
Which is why schools need nothing from us. Designing, Run and Debug are the whole classroom loop — a pupil draws the schema, presses ▶︎, and the application opens and works, with the debugger, the reports and the data browser all there. That is a full term's teaching on every machine in the room, without a key, without registering, and without anybody having to ask us for anything.
Building an application is the line, and it is one line rather than two
(changed 21 August 2026). A test build used to be free as well. It is not any more,
and the reason is honesty: an unsigned .app runs on any Mac whose owner
right-clicks it once, so “test builds are free” quietly meant “shipping is free if you
do not mind the warning”. Either building is what a license is for, or it is not.
Pricing
Two products. No seat counting, ever.
The prices below are what has been decided, and the subscriptions are on sale now — building needs one, in the beta exactly as after 1.0.
G4MJGXOA takes 30 % off your first year.
Both products, redeemable until 1 January 2027. It is the first year that is discounted, not the renewals — every year after that is the full price. The Buy buttons below apply it for you — nothing to type.
Beta
The whole IDE for designing, running and debugging — a complete
evaluation with no clock on it. Building an .app needs a
subscription, in the beta too (changed 22 August 2026).
- Design, Run, Debug — every feature of the loop
- The examples, the debugger, the data browser
- No key, no registration, no trial clock
- The build stamp marks what was made with the beta
Neuridion
For one person, on up to three Macs. Everything the single-user product can do, with no limit on what you build with it.
- Unlimited applications, unlimited customers
- Signed and notarised release builds
- Every version released during your year
- Everything you ship is royalty-free — no checks in built apps
- The 119 € stays as long as your subscription runs uninterrupted
- Client/Server — that is PRO
Neuridion PRO
Everything above, plus the Client/Server build — the tick box that turns one application into a server and the clients that talk to it.
- Everything in Neuridion
- Client/Server builds
- Unlimited seats — nothing to count, nothing to declare
- Record locking, one shared database
- The server distributes the client itself
How the license behaves
Four sentences, and none of them has a trapdoor.
Every application you have already built runs and never checks a license — that is the promise, untouched. The IDE keeps designing, running and debugging with no key; what waits until you renew is making a new build. You rent the workshop, never the things you make in it.
Whatever the price was when you signed up stays your price, as long as the subscription runs without a gap. We do not have to build anything to keep that promise — our payment provider behaves that way by itself. The price of a new subscription can change over time; yours does not.
Every version released during your twelve months is included — download as many as you like, and Neuridion tells you when a new one is out. When the subscription ends, the version you have stays yours to design, run and debug with, with no key. What waits for the next subscription is the same one thing as everywhere else on this page: a new version, and a new build. No surprise paywall halfway through an update.
Build for your own customers, as many as you like. What is not allowed is acting as a build service for other developers who have no license — taking their projects and handing back finished applications. Nothing else here can cost you your license.
Neuridion 0.9.4 Beta
Free, complete, and no account to create. Open one of the example projects on your first launch — Harbour Supply ships with all 7,628 of its invoices, so there is something real to take apart.
