Is this the "one right stack" for my product?

No. There is no single right stack, and anyone who tells you otherwise is selling something. This is an opinionated starting point: the defaults we would reach for on a build of the shape you describe. The right final architecture always comes from your real data, constraints, and team. Treat every pick as a decision to defend, not a default to accept blindly.

How does it decide what to recommend?

It maps your answers (product type, how central AI is, scale, team shape, real-time needs, and hard constraints) onto a concrete stack for each layer. For example, an AI-native product gets a Python model layer isolated behind a JS product API; a solo-founder MVP gets a single-language stack to remove coordination overhead. The logic is a set of transparent rules, not a black box.

Why is AI called out as its own layer?

Because when a model is in your product, it behaves unlike normal code: it drifts, it costs money per call, it can be slow or wrong, and providers change. Treating the AI layer as a first-class concern (with a swappable abstraction, evals, logging, and a fallback path) is the difference between an AI feature that survives contact with users and one that quietly breaks.

Why do you need my email?

We show your recommended stack on the spot and send a copy, plus a short follow-up on the trade-offs behind each pick. We do not spam, and we never sell or share email addresses.

What if I want this pressure-tested against my real situation?

Book a Discovery Sprint. In 1-2 weeks we take these defaults, weigh them against your actual constraints, data, and team, and hand you an architecture you can build on with confidence, not a generic answer.

What should you build it with?

Answer 6 quick questions about your product and get an opinionated stack (frontend, backend, data, infra, and the AI layer) with the reasoning and the honest trade-offs behind every pick. About 2 minutes. A starting point, not a spec.

Why founders use it

A fast, opinionated second opinion

Before you commit to an architecture you will live with for years, get a strong default to defend or adapt.

Opinionated, not generic

You get a specific stack across five layers (frontend, backend, data, infra, and AI) with a one-line reason for each pick, not a wall of options to sift through.

Honest about trade-offs

Every recommendation ships with the things to watch: where a pick will bite you, what to revisit at scale, and which choices are meant to be thrown away later.

Takes about 2 minutes

Six quick questions about your product, scale, team, and constraints. No login, no brief, no spreadsheet; answer what you know and go.

Architecture is opinion

A stack recommendation is a starting point. Architecture is what ships.

The picker gives you a strong default. We weigh it against your real constraints, data, and team, then build the architecture that holds up in production.

Five stack layers

Every recommendation covers five layers

A complete stack, not a single-framework answer, because products run on more than one layer.

Frontend

The surface layer users interact with: framework, state management, and build tooling.

Backend

API design, business logic, auth, and the service architecture that holds it together.

Data

Database engine, caching layer, and how data flows between services.

Infrastructure

Hosting, CI/CD, observability, and how the system runs in production.

AI layer

Model provider, prompting strategy, evals, logging, and fallback paths.

From picker to production

Every pick has trade-offs. We know what they are.

Where a framework will bite at scale, what to revisit after Series A, and which choices are meant to be thrown away. That is the conversation the picker starts; we finish it.

Turn a stack into an architecture

This tool gives you a strong default. A Discovery Sprint weighs it against your real constraints, data, and team, and hands you an architecture and a plan you can build on with confidence, in one to two weeks, not months.
