01
Production-grade by default
Every system we release is tested, documented, and hardened before it ships. We build what we would be willing to run in production ourselves — because we do.
About Cornerstone
We build the foundations other software stands on.
Cornerstone is an independent software studio. We design and ship the production layers every serious product needs — authentication, billing, multi-tenancy, and the infrastructure around them — so our customers can spend their time on the product itself.

Typical first response from our team
Why we exist
The same infrastructure, rebuilt on every project. We decided to solve it once.
Across years of client and product work, our team kept starting from the same place: two to three months rebuilding authentication, billing, permissions, and admin tooling before a single line of actual product got written.
It was the least differentiated work in every engagement, and the most dangerous to get wrong. So we built it properly, once — with the tests, documentation, and security review that production genuinely requires.
That system became Cornerstone. Every product we release is held to the same standard.
Our standards
What we will not compromise on.
02
Transparent, one-time pricing
No subscriptions, no seat counts, no renewal traps. Our customers pay once and keep what they bought, permanently.
03
Full ownership, no black boxes
Every purchase includes complete source access under a clear licence. Our customers are never dependent on us to keep their business running.
