One prompt session vs one genome
| Model | Flask + Django + NestJS | Consistency | |---|---|---| | Three separate AI sessions | Three different schemas, auth bugs, divergent APIs | Low — manual reconciliation | | One genome → three renders | Same entity model, same routes semantics, same ADRs | High — deterministic IR |
Stack coverage (2026)
| Stack | Role | |---|---| | Flask + Next.js | Stable — Python sync, broad extension ecosystem | | FastAPI + Next.js | Stable — async API-first | | Django + Next.js | Stable — batteries-included admin patterns | | NestJS + Next.js | Stable — TypeScript enterprise APIs | | Laravel, Rails, .NET, Go, Java | Stable web backends | | Tauri + Rust | Desktop runtime | | Salesforce Apex, SAP CAP, Dynamics 365 | Enterprise platform-native |
Preview stacks ship with a PREVIEW banner until parity gates clear — see stack tiers in product docs.
What stays identical across stacks
- Entity definitions and relationships from the blueprint
- User stories → acceptance criteria → test scaffolds
- Auth flow semantics (httpOnly cookies on web)
- Multi-tenant filter requirements on data queries
- Compliance overlays (SOC 2, GDPR, HIPAA when enabled)
- ADRs and traceability matrix (stack choice is itself an ADR)
What differs (correctly)
- ORM idioms (SQLAlchemy vs Prisma vs Eloquent)
- Project layout and dependency management
- Migration tooling (Alembic vs Django migrations vs TypeORM)
- Framework-specific middleware and DI patterns
Who needs multi-stack generation
- Agencies standardizing delivery while matching client stack mandates
- ISVs offering on-prem Flask and cloud NestJS variants
- Enterprises piloting one stack while production standardizes another

FAQ
Is output byte-identical across stacks?
No — idioms differ by design. Semantic parity (entities, routes, auth, compliance) is what the genome guarantees.
Can I switch stacks after the first generation?
Yes. Edit the blueprint if needed, change stack selection, regenerate from the same genome.
How does Archiet compare to JHipster or similar?
JHipster generates one Java-centric stack. Archiet generates fifteen backends from one architecture model, including non-JVM stacks.
