The architecture of an owned system. No rent, no limits.
We replace scattered SaaS subscriptions with one cohesive engine — open-source, hosted on your infrastructure, engineered to convert. The same stack we use to build category leaders.
§ Tech.01
Why own instead of rent?
We build on open-source so you have zero vendor lock-in. No per-seat fees, no trapped data, no arbitrary price hikes.
01
Zero SaaS Fees
You pay for raw server compute. A £30/mo server can replace £3,000/mo in SaaS licenses.
02
100% Data Sovereignty
Your customer data lives in your database, on your infrastructure. You can export it, query it, and delete it at will.
03
Unrestricted Extensibility
Need a custom feature? We write the code. You're never waiting for a vendor's product roadmap again.
§ Tech.02
The flow of data.
A unified system means data flows frictionlessly from the first click to the final invoice.

§ Tech.03Six Layers
A composable, owned stack.
Every project ships on the same backbone. Layers are independent — swap any one without rebuilding the system.

“A headless CMS your team will actually use, with TypeScript-native fields and zero vendor lock.”

§ Tech.04The wiring
Why this stack stays cheap as you scale.
No per-seat fees. No per-execution tax. No vendor with a contract. You pay for the hardware that runs it — and that's it.
// Economics
Owned cost stays flat. SaaS cost compounds.
A typical SMB on rented SaaS pays £1,200/mo at 5 seats. At 20 seats, that's £4,800/mo — and the vendor controls the roadmap. With STACKD, the only growing line is the box you rent for £30/mo. Everything else is amortised over the build.
