What is Convex?
Convex is a modern backend platform that provides developers with a reactive, realtime database and serverless functions, all written in pure TypeScript, designed to make building full-stack applications dramatically simpler. Traditional backends require stitching together a database, an API layer, realtime infrastructure, and more, each with its own complexity. Convex unifies these into one cohesive, reactive platform where your data updates live across clients automatically and your backend logic is just TypeScript functions — removing huge amounts of boilerplate and letting developers build sophisticated, realtime apps with remarkable ease.
The platform's defining quality is reactivity: when data changes, every part of your app that depends on it updates automatically and in real time, without you having to manage subscriptions, caching, or synchronization manually. You write your backend logic as TypeScript functions that query and mutate the database, and Convex handles the realtime sync, consistency, and scaling. This eliminates a whole category of difficult problems around state management and live data, and combined with end-to-end type safety, it makes building modern, interactive applications far faster and less error-prone. It's especially popular in the React and Next.js ecosystem.
Convex is used by developers and teams building modern, interactive web and mobile applications who want realtime functionality and a great developer experience without backend complexity. The value is simplicity and power together: it removes the hard parts of building realtime, full-stack apps — sync, state, infrastructure — and replaces them with a clean, reactive, type-safe platform. For developers who want to build apps where data is live and collaborative by default, without wrestling with the underlying plumbing, Convex offers a genuinely innovative approach. As modern apps increasingly demand realtime experiences, its reactive backend has won a growing following among developers who value both productivity and capability.
What is Supabase?
Supabase is an open-source backend-as-a-service platform that gives developers everything they need to build an application's backend, built around the trusted PostgreSQL database. Building a backend traditionally means assembling and maintaining a database, authentication, file storage, APIs, and real-time infrastructure — a lot of undifferentiated work before you even start on the features that make your product unique. Supabase provides all of those pieces, ready to use and well integrated, so developers can focus on building their product rather than reinventing backend plumbing. It's frequently described as an open-source alternative to Firebase, but with the power and openness of Postgres at its core.
The platform centres on a full Postgres database — a mature, powerful, standard relational database, not a proprietary one — which means developers get real SQL, relationships, and the vast Postgres ecosystem rather than being boxed into a limited data model. Around the database, Supabase adds authentication with support for email, social logins, and more; file storage; auto-generated APIs so you can query your data instantly; real-time capabilities so apps can react to changes live; and edge functions for custom server-side logic. Because it's open source, teams can self-host for full control or use the managed cloud service for convenience, avoiding the lock-in that worries many developers about closed backend platforms.
Supabase has become a favourite of startups, indie developers, and teams who want to move fast without sacrificing the robustness of a real database or the freedom of open source. The appeal is speed plus solid foundations: you can stand up a production-ready backend in an afternoon, yet you're building on Postgres, which scales and won't trap you. Its excellent developer experience, generous free tier, and strong community have fuelled rapid adoption. For anyone building a web or mobile app who wants to skip months of backend setup while keeping power and portability, Supabase offers a compelling, modern foundation that has quickly become one of the most loved tools in the developer ecosystem.
