One architecture
Every stack uses the same open-source foundation. Adding a second stack adds modules, not new infrastructure.
Nothing you don't need
Stacks are starting points. Every build is scoped to your actual workflow — you never pay for modules you don't use.
Yours outright
No platform fees. No SaaS subscriptions. The entire system lives on infrastructure you own.
Not a perfect fit?
We scope everything custom. If your business doesn't fit neatly into one of these — or you want to mix modules across industries — tell us about your setup. We'll propose the right combination.
01 Tell us how your business runs
A few paragraphs or a 20-minute call — whichever is easier.
02 We map it to modules
We identify which modules match your actual workflow. No upselling, no bloat.
03 Fixed quote, one working day
Scoped to exactly what you need. No retainer required to find out what it costs.
04 Built and handed over
Full documentation, full ownership. No dependency on us to keep it running.
