Why stack choices belong in the blueprint
When you create a technical blueprint, SpecKit asks for choices such as the frontend, backend, database, authentication, storage, and payment services. These selections give the generated documents a concrete vocabulary instead of leaving every implementation decision abstract.
A stack should follow the project constraints rather than fashion. Consider the team's experience, deployment environment, data model, integrations, expected maintenance, and any existing systems before accepting or adjusting a recommendation.
How choices affect documents
| Stack option | Blueprint impact |
|---|---|
| PostgreSQL / MySQL | A relational data model can describe tables, keys, relations, indexes, and SQL-oriented constraints. |
| MongoDB | A document model can describe collections, nested structures, indexes, and validation rules. |
| Next.js / React | The architecture and user-flow documents can reference routes, server and client boundaries, state, and responsive interface behavior. |
| Stripe / Midtrans | The API and business-rule documents can cover checkout states, webhook handling, signatures, retries, and transaction verification. |
Use conventions as context, not generated code
Technology choices help SpecKit express data types and responsibilities in conventions that fit the selected ecosystem. The result is still a planning artifact: review versions, security assumptions, error behavior, and provider-specific details against official documentation before implementation.
The next step is the adaptive AI interview, where unresolved product and system questions can be clarified before documents are generated.
