The world's most advanced front-end ORM, self-built. Also houses homegrown auth, payments (Stripe integration) and . I use it for 5 of my projects: Artiry, Tutoic, PromptGrid, Happenlist and CultureTest.

Why most advanced frontend ORM in the world?
- Type-safe live queries (query types with code generation)
- Optimistic updating of all active queries from any CUD mutation in the application
- Type-safe w.r.t. joins (join-fetching related entities also expands the result types)
Built-in write-ahead-log mutating
- Extremely minimal rerendering when queries update
- Rapid mutations intake (e.g. every keypress) causes no performance issues due to built-in write-ahead log (WAL)
- Seamless integration of optimistic frontend-originating updates and data updates coming from the server

Made it work for both SPA React apps and NextJS apps.
