Not A starter template
create-react-app gets you a folder and a build pipeline. CleenUI gives you 524 production endpoints, 60+ accessible components, a 300-table data model, and 14 working modules.
Once you're convinced the category is right, the question becomes which footprint to license. Six structural choices set CleenUI apart from every other contender — the architect-led model, real production usage, stored-procedure-first data access, 14 actual production modules, AI-first design, and the modular-monolith deployment shape.
Half the misunderstandings about CleenUI come from fitting it into the wrong category. Four mental buckets it deliberately doesn't belong in.

Retool and Bubble run on their infrastructure with their data models. CleenUI is source code you deploy onto your own cloud, modify freely, and own outright.
shadcn/ui and MUI ship UI primitives. CleenUI ships the full stack the UI is calling into — API, services, repositories, database, background jobs.
Refine and ABP give you scaffolding patterns. CleenUI gives you an actual production application — auth flows that work, multi-tenant guards that work, audit logs that work.
Not "we have more features." Structural choices that compound — each one harder to add later than to start with.
Every CleenUI license starts with a no-cost 30-minute architecture review with the architect (Shawn Livermore — 25+ years modernizing enterprise platforms, bestselling architecture author with Wiley). No sales engineers, no AE handoff. You talk to the person who designed the codebase.
CleenUI is in production at three companies today — MiCard.io (digital contact cards on web + iOS), is.fun (content creation with structured syntax), FNDRS.io (closed-loop exit ecosystem). All three shipped real platforms within months of licensing.
No Entity Framework, no ORM mystery. Every query goes through Dapper + ADO.NET against named stored procs — 700+ of them. Query plans are predictable, performance is observable, DBAs can read the data layer. This is the modernization choice .NET shops have been waiting for.
Auth, accounts, support tickets, observability, translations, notifications, messaging, tasks, AI orchestration, fonts, legal policy, categories, assessments, marketplace. Each one is a complete vertical slice — UI, API, services, repos, schema, background jobs — not a folder with a TODO.
Ships with Claude/Cursor/Windsurf agent skills (Setup, Builder, Theme), a documented MCP server pattern, llms.txt for crawler discovery, OpenAPI 3 specs, and a deliberately consistent codebase shape that AI tools can pattern-match against. The codebase teaches the model how to extend it.
One deployable artifact, four-environment CI/CD, in-process service composition. Microservices buy you operational complexity in exchange for scaling problems most teams don't have. The modular monolith pattern gives you the architectural clarity without the distributed-systems tax.
Every CleenUI engagement begins with a 30-minute architecture review with the person who designed the codebase. Not a sales-engineering hand-off, not a templated discovery call. The architect listens to your stack, your team shape, your timeline, and your three biggest modernization headaches — and tells you whether CleenUI fits or doesn't.
When it fits, the engagement is scoped to your reality: which modules you'll use as-is, which you'll extend, what your CI/CD setup looks like, which cloud you're deploying onto. There's no per-seat pricing tier to upsell into, no usage cap that suddenly becomes a renegotiation. One license, full source, perpetual usage, ongoing architectural advice on the cadence you need it.
When it doesn't fit — which is sometimes, and the architect will tell you — you get a half-hour of senior architectural counsel about how to think about your problem, and you go your way with that.
Per-competitor write-ups. Each linked page does the apples-to-apples comparison so you can see the specific tradeoffs in context.
30 minutes with the architect. Bring your stack diagram, your top three modernization headaches, and questions. Leave with a scoped engagement plan — or a clear answer that CleenUI isn't right for you.
