01 — Workflow

A backend, end to end.

Four steps. Real output. Drop it in your codebase and ship.

Describe

Plain English. Paste a PRD, a doc, or just type.

Reason

Simplicit reasons about entities, stack, and trade-offs in real time.

Generate

Schema, routes, auth, jobs, IaC. Every file production-grade.

Deploy

One click to GitHub, Railway, Vercel, Fly. Or download the zip.

02 — Architecture

An AI systems architect, not a chatbot.

Simplicit reasons about your domain like a senior engineer would: bounded contexts, data ownership, failure modes. The output is a complete architecture you can defend in a review.

Service & data-flow diagrams

Auth, RBAC, and tenancy decisions

Caching, queues, and rate-limit strategy

Cost & latency annotations

03 — Output

Real, opinionated, hand-readable code.

No spaghetti. No leaky abstractions. Simplicit follows the conventions of the framework you pick, with named modules, typed boundaries, and tests where they matter.

TypeScript end-to-end, with Zod or Valibot schemas

Drizzle / Prisma migrations included

OpenAPI spec + generated SDK package

Pluggable: works with your linter, tests, CI
