Archiet vs Create T3 App — when the T3 scaffold isn't the right starting point

The comparison

| Decision factor | Create T3 App | Archiet | |---|---|---| | Generation model | Interactive CLI wizard — pick TypeScript, Tailwind, tRPC, Prisma, NextAuth. | Generate from your PRD or requirements doc. | | What's included | Application scaffold with chosen libraries configured and wired. | Complete domain model: entities, routes, services, migrations, tests — plus docs and compliance. | | Domain model | Not generated. You write every Prisma schema model, every tRPC router, every resolver. | Extracted from your requirements. Every entity becomes a model + migration + service + tests. | | Stack | Next.js + TypeScript + tRPC + Prisma + NextAuth. TypeScript-only. | Flask, FastAPI, Django, NestJS, Laravel, Rails, .NET Core, Go Chi, Java Spring Boot — your choice. | | Auth security | NextAuth session cookies — solid defaults. | JWT in httpOnly cookies + workspace-scoped tenant filter on every query. | | Multi-tenancy | Not generated. You implement organisation/workspace isolation on top of Prisma. | Built-in: row-level tenant filter, workspace-scoped queries, audit trail for sensitive ops. | | TypeScript strict mode | tRPC + Prisma provide excellent end-to-end type safety. | When generating NestJS/Next.js frontend: strict mode, zero any, tsc --noEmit must pass before delivery. | | Architecture docs | Not generated. | MADR v4 ADRs, traceability matrix, security posture doc. | | Compliance documents | Not generated. | HIPAA, DORA, GDPR, PCI, SOC 2 — populated from entity model when compliance overlays flagged. | | Quality scoring | Not measured. | 4-dimension quality score — publish-eligible at 80/100. CRITICALs block delivery. | | Best fit | TypeScript-first teams that want opinionated fullstack scaffolding with end-to-end type safety. | Multi-stack or compliance-heavy products, enterprise B2B, any team that wants domain-complete generation rather than a scaffold. |

Where T3 wins: if TypeScript end-to-end type safety is a hard requirement and tRPC's RPC model fits your API design, T3's scaffold is one of the most coherent starting points available. The type inference from Prisma schema through tRPC router to React component is genuinely best-in-class.

Where the fit breaks: T3 is a scaffold. Your Prisma schema, your tRPC routers, your data access patterns, your business logic — none of those are generated. For a product with 10+ entities, multi-tenant isolation, and a compliance requirement, the scaffolding is maybe 15% of the work.

A pattern we see: teams that love tRPC's type safety choose Archiet for the NestJS + Next.js stack (which gives them typed API contracts at the HTTP boundary), letting Archiet generate the full domain model rather than assembling it router by router.

What Archiet generates that T3 doesn't

Every Archiet generation ships:

• The complete backend in your chosen stack — your actual domain model, generated from requirements
• Database schema + migrations for every entity
• Multi-tenant data isolation on every protected query — not a pattern you retrofit later
• docs/decisions/ — one MADR v4 ADR per material decision
• docs/traceability/ — story-to-code mapping
• docs/compliance/ — HIPAA, DORA, GDPR, SOC 2 docs when applicable
• Quality score across 4 dimensions — publish-eligible threshold is 80/100
• Synthetic Boot Test — the generated codebase is verified to start before delivery

If your team is TypeScript-first and tRPC's type model fits your API design, T3 is an excellent scaffold. If you need the full domain model generated from requirements — especially with enterprise or compliance requirements — that's what Archiet is for.
