Khufu ships a SaaS to production in 7 days thanks to a single, deliberately fixed stack: Next.js on the front end, NestJS on the back end, Prisma as the ORM, PostgreSQL as the database, all deployed on managed cloud hosting. One language — TypeScript — from the browser down to the database. This is not a trend: every layer is chosen because it serves two goals at once, delivery speed and long-term maintainability. Here is why.
One stack, one language, from front end to database
The first decision that saves a week is not having to choose. Khufu uses the same stack on every project, with TypeScript everywhere: a developer moves from front end to back end without switching language, mental model or tooling. Types shared between client and server wipe out an entire class of bugs — the ones that appear when the front end and back end no longer agree on the shape of the data.
- Strict TypeScript from the browser to the database: one language to master, zero context-switching friction.
- A fixed stack: no time wasted re-evaluating tools on every project.
- Reusable patterns from one product to the next — auth, payments and dashboards are already battle-tested.
Next.js: a fast front end with no hidden debt
Next.js handles rendering, routing, the API and SEO in a single framework. In practice, we start a product with authentication, server-rendered pages and clean SEO in hours, not days. And because it is standard React on a heavily documented foundation, the code stays readable and easy for any developer to pick up — not a homegrown framework only you would understand.
NestJS, Prisma and PostgreSQL: a structured, typed back end
On the server, NestJS enforces a clear architecture — one module per business domain — that avoids the classic spaghetti of MVPs thrown together in a hurry. Prisma generates a typed client from the database schema: queries are checked at compile time, migrations are versioned, and PostgreSQL provides a solid relational database that handles everything from the V1 up to tens of thousands of users without a rewrite.
- NestJS: enforced structure, so the code stays maintainable even after six months of changes.
- Prisma: single schema, versioned migrations, typed queries — far fewer data bugs.
- PostgreSQL: the reference relational database, free, with no artificial limits.
A fixed stack is not dogma: it is what lets us ship in 7 days what others build in three months, without piling up the debt you have to repay later.
Managed cloud hosting: zero ops, automatic scaling
We deploy on managed cloud hosting (Vercel on the front end, Cloud Run on the back end): no server to administer, a deploy on every commit, automatic scaling with traffic. You do not pay a full-time DevOps engineer for a V1, and the infrastructure keeps up when the product takes off. Continuous deployment is in place from day one — the product is live on a real URL by day 2.
Why these choices serve both speed AND maintainability
Most teams treat the two as opposites: move fast and pile up debt, or build cleanly and take months. The Khufu stack refuses that trade-off. Every layer is mainstream, documented and typed, so it is fast to write today and easy to hand over tomorrow. That is what lets us ship a production-ready V1 in 7 days, for a fixed price of €15,000, with source code you own and any developer can take over — not a prototype to throw away in six months.
