What STLa is for

STLa is aimed at people who need to inspect or repair STL files before printing, sharing, or reusing them.

Open STL files from your Mac.
Inspect for open edges, non-manifold geometry, and face-direction issues.
Run a repair workflow with progress feedback.
Save a repaired STL and a JSON report.

Version 1 approach

The current version is intended to stay straightforward and privacy-minimal.

No account is required.
No third-party analytics are planned for version 1.
Files are chosen by the user and handled locally on the Mac.
Basic shape creation is available as a secondary workflow.
