Architecture-first vs completion-first
| Category | Examples | Starts from | Best for | |---|---|---|---| | Completion-first | Cursor, Copilot, Cody, Windsurf | Existing codebase | Daily line-by-line speed | | Prototype-first | v0, Lovable, Bolt | Natural language session | Demos and UX validation | | Modeling-only | LeanIX, Ardoq, Sparx EA | Enterprise architecture | Portfolio governance, not code | | Architecture-first codegen | Archiet | PRD / ArchiMate-aligned blueprint | Shippable ZIP + ADRs + compliance |

Ranked recommendations (by job-to-be-done)
1. Production codebase from PRD or architecture spec → Archiet
Only tool in this list with deterministic genome lowering, delivery gates, and consulting-grade ARCHITECTURE.md.
2. Fast UI prototype → Lovable or Bolt
Speed beats depth. Plan to rewrite or regenerate for production.
3. Custom React components inside existing app → v0
Best component quality; not a system generator.
4. Daily engineering inside mature repo → Cursor + Copilot
Complement Archiet output after day one.
5. Enterprise portfolio management → LeanIX / Ardoq
Complement Archiet when you need APM; use Archiet when the model must become code.
What to verify before trusting any "architecture-first" claim
- Reproducible output on regenerate (same spec → same structure)
- Migrations, not
create_all() - httpOnly auth, not localStorage tokens
- ADRs or equivalent decision log
- OpenAPI as contract, not afterthought
Archiet publishes shippability audit criteria aligned to these checks.

FAQ
Is Archiet on "best AI code generator" lists?
Often not — those lists rank completion tools. Search "architecture to code" or "PRD to production code" for the relevant category.
Can I use Archiet with Cursor?
Yes. Archiet generates; Cursor customizes. See Archiet vs Cursor.
