What is StackAlchemist

THE GAP BETWEEN
IDEA AND ARCHITECTURE
IS WIDER THAN IT SHOULD BE.

Every SaaS starts the same way: an idea, a napkin sketch, and then weeks of grinding through the scaffolding before you write a single line of real business logic. StackAlchemist eliminates that grind. You describe what you're building. We hand you a compiled, production-ready codebase.

The Problem

Scaffolding is solved work. Stop solving it.

A typical SaaS scaffolding sprint — entity modeling, API layer, database migrations, auth, Docker setup, folder structure — eats two to four weeks before you ship anything. That's two to four weeks of work that looks the same on every project.

Every developer who has built more than one thing knows this feeling: you've done this before. The pattern is familiar. The implementation is just... tedious. Necessary, but not interesting.

The interesting part is the idea itself. The domain logic. The thing only your product does. That's where you should be spending your time.

The Solution

Describe it. Receive it. Ship it.

StackAlchemist takes a natural language description of your SaaS — your entities, relationships, and API endpoints — and generates a complete, compilable source repository in minutes.

Not a template. Not a starter kit. A real codebase, shaped precisely around your schema, with your naming conventions, your business entities, your API surface.

The repository compiles on the first try — or we auto-correct it and try again. That's not a marketing promise. It's a technical guarantee baked into the delivery pipeline.

How It Works

01

Describe Your System

Use Simple Mode to describe your SaaS in plain language, or Advanced Mode to model entities, relationships, and API endpoints with precision. Either way, you're in control of the schema.

Simple Mode — natural language prompt

Advanced Mode — visual entity modeler

02

Choose Your Tier

Blueprint gives you the architecture document. Boilerplate gives you the full source code. Infrastructure gives you everything, including cloud deployment. Pick the depth you need.

03

The Transmutation Begins

Our generation engine applies the Swiss Cheese Method: deterministic Handlebars templates for structure, LLM intelligence injected into the business logic layer. The result is code that looks hand-written, not generated.

Template engine + LLM injection

04

The Compile Guarantee

Before your archive is assembled, the generated code is run through the actual compiler. If it fails, the error output is fed back to the LLM for correction — up to three times. Delivery only happens when the build is green.

dotnet build → auto-correct → retry

05

Download and Ship

You receive a complete ZIP archive: source code, migrations, Docker Compose, environment configuration. Clone it, run docker compose up, and your dev environment is running in under five minutes.

The Method

The Swiss Cheese Method

Most AI code generators produce either too much structure (rigid, one-size-fits-all boilerplate) or too little (hallucinated, inconsistent, non-compilable fragments).

StackAlchemist uses a different approach. The outer structure — file layout, project references, import paths, class signatures — is defined by static Handlebars templates. Deterministic. Reliable. Predictable.

The holes in the cheese — the business logic, domain validation, query implementations — are filled by the LLM, guided by your schema. Intelligence applied precisely where variability is expected. Structure preserved everywhere it matters.

V1 Stack

.NET 10 Web APIBackend

RESTful API with controllers, repository pattern, model validation, and Entity Framework-ready data access. Clean architecture, proper layering.

Next.js 15Frontend

App Router, TypeScript strict mode, Tailwind CSS. Type-safe API client generated from your schema. No config required to run.

PostgreSQLDatabase

Schema migrations scripted from your entity definitions. Foreign keys, indexes, and constraints modeled from your relationships.

SupabaseAuth + Storage

Row Level Security policies scaffolded for your entities. Auth flows wired into the frontend. Ready for production the moment you deploy.

Docker ComposeDev Environment

One command to spin up the entire stack locally. Database, API, and frontend orchestrated together with proper networking and volume mounts.

AWS CDK (Infra tier)Cloud

Lambda, RDS, S3, CloudFront — all as TypeScript infrastructure code. Deploy to production with a single CDK deploy command.

Stop scaffolding. Start building.

The architecture is the easy part now.
