// why_this_stack[]
## Why This Stack
01.Retool cuts UI development time by 60–80% for CRUD-heavy tools — only go custom React if you need it.
02.SSO via Google Workspace or Azure AD means employees never manage a separate password.
03.Self-hosted on Hetzner VPS keeps sensitive internal data out of third-party clouds if required by policy.

## Common MVP Features
—Role-based access (admin / editor / viewer)

—Audit log of all data mutations
—Bulk import via Excel / CSV upload
—Webhook or API integration with existing internal systems
// risk_flags[]
## Risk Flags
!Scope creep is the #1 killer of internal tools — lock the feature list before development starts.
!Data migration from legacy Excel/Sheets takes 2–4× longer than estimated — plan for it explicitly.
