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

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.

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

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
Minimal-API endpoint groups with a Dapper repository per entity over Npgsql. One real file each for the model, the repository and the CRUD endpoints.
Next.js 16Frontend
App Router, TypeScript strict mode, Tailwind CSS. Type-safe API client generated from your schema. Copy .env.example and it runs.
PostgreSQLDatabase
Schema migrations scripted from your entity definitions. UUID primary keys and foreign key constraints modeled from your relationships.
SupabasePreinstalled
The client library and its environment variables ship wired through Docker Compose. The migration enables row-level security — the policies and the auth flows are yours to write.
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
A TypeScript stack — VPC, ECS Fargate behind an Application Load Balancer, RDS PostgreSQL. Terraform and Helm equivalents ship beside it.
Stop scaffolding. Start building.
The architecture is the easy part now.
