Convex
Reactive backend with realtime database
Overview
Convex is a backend-as-a-service built around a reactive database that pushes updates to the frontend automatically. Every query becomes a live subscription, so realtime apps need little extra plumbing. It bundles database, functions and scheduling, and pairs well with auth providers like Clerk and Auth0.
