Frontend Frameworks

3/5

Convex is a real-time BaaS with a first-class React SDK — useQuery and useMutation hooks sync server state to React components without manual data fetching.

Railway

Modern PaaS for deploying apps, databases, and workers. Git-based deployment with infrastructure as code approach.

Usage Based

Hosting & Cloud

3/5

Convex's self-hosting docs name Railway as a deployment target, and Railway's template registry carries a Convex backend template.

Fly.io

Docker-native edge hosting platform running apps in Firecracker microVMs across 35+ global regions. Scale-to-zero by default, with managed Postgres and built-in anycast networking.

Usage Based

Hosting & Cloud

3/5

Convex's self-hosting documentation lists Fly.io among the platforms the open-source backend is known to work with.

Backend Frameworks

3/5

Express is a Node.js framework; Convex is a managed TypeScript-native backend — build-your-own vs managed.

Axum

Axum is an ergonomic, macro-free web framework for Rust built on top of Tokio, Hyper, and Tower. It offers type-safe request extractors, composable middleware via Tower, and minimal boilerplate for building async HTTP APIs.

Backend Frameworks

3/5

FastAPI is a Python framework; Convex is a managed TypeScript-native backend — build-your-own vs managed.

Supabase

Open-source Firebase alternative built on PostgreSQL. Provides a full backend stack with database, authentication, real-time subscriptions, file storage, and edge functions — deployable on Supabase Cloud or self-hosted.

Freemium

Databases

4/5

Both modern backend platforms; Convex is TypeScript-native with reactive queries, Supabase wraps PostgreSQL with auth and storage.

Firebase

Google's platform for building web and mobile applications with real-time database, authentication, hosting, and serverless functions.

Freemium

Databases

4/5

Both real-time backend services; Convex uses a TypeScript-native reactive model, Firebase uses NoSQL collections with real-time listeners.

Xano

No-code backend platform that lets you build, host, and scale a production-grade REST API with a managed PostgreSQL database — no server setup or coding required.

Freemium

No-Code / Low-Code

3/5

Convex is a reactive, TypeScript-first BaaS; Xano targets no-code builders. Both eliminate custom backend code, but Convex suits developers while Xano suits non-technical builders.
