Compose deliberately
Presets resolve explicit modules with declared files, routes, tables, environment variables, dependencies, and conflicts.

Build the stack.
Own the product.
Stackiln turns a verified base and composable modules into a production-oriented Next.js product—then gets out of the way.

A calmer foundation
Scaffolding that respects what happens next.
Most starters optimise for minute one. Stackiln is designed for the months after generation—when products diverge, teams customise, and safe change matters.
Generate transactionally
Inspect a read-only plan first. Stackiln writes through a sibling stage and commits only after the product validates.
Own every line
The result is a standalone Next.js workspace. No generator runtime, private registry, or framework-shaped deployment lock-in.

Plan before mutation
See the product before Stackiln writes it.
The planner resolves dependencies, rejects collisions, and lists the exact output. Apply uses a sibling staging directory; managed-file hashes protect later customisation.
