12 Best Convex Alternatives in May 2026

Convex is the reactive backend-as-a-service — TypeScript-first backend with real-time sync, serverless functions, and a database that automatically reactive-updates client UIs when underlying data changes. Convex's differentiator is the deeply integrated reactivity: queries automatically reactive across clients, no polling or websocket plumbing, with strong TypeScript ergonomics.

Supabase is the closest BaaS alternative with broader scope (Postgres + auth + realtime + storage + edge functions) — usually preferred when Postgres-compatibility and traditional SQL matter more than reactivity. Firebase is the Google alternative with mature mobile SDKs and Firestore's document model. PlanetScale, Neon, and Xata target serverless Postgres without the BaaS bundling. For specifically reactive databases, RethinkDB (legacy) and Meteor (legacy) pioneered the model; Convex has modernized it. Liveblocks targets real-time collaboration features specifically (cursor sync, presence, conflict resolution) rather than full backend. Replicache and Reflect target sync-engines for offline-first apps with different architecture. Yjs handles CRDT-based collaboration. Triplit is the newer competitor with similar reactive sync positioning. Jazz.tools targets local-first sync with similar focus. For specifically WebSockets and realtime alone, Supabase Realtime, Pusher, Ably, and PartyKit handle this without full BaaS. For specifically TypeScript-first backend with strong types, tRPC + Postgres handles different patterns. Convex's distinctive position is the reactive-database model with TypeScript-first DX — for teams building reactive UIs (chat, collaboration, dashboards), Convex eliminates significant plumbing. For teams who want traditional REST/GraphQL with manual real-time, Supabase often wins. The practical decision: Convex for reactive TypeScript-first apps where real-time is a product requirement; Supabase for traditional Postgres-anchored BaaS with realtime as one feature; Firebase for mobile-first with mature SDKs; PlanetScale/Neon for pure serverless databases; Liveblocks when collaboration features matter more than full backend; Triplit for similar reactive-sync alternatives.
