Convex vs Supabase

Both Convex and Supabase offer a freemium pricing model, include a free tier, and support self-hosting. The primary distinction lies in their core focus and community adoption. Convex is purpose-built for real-time data synchronization, offering a reactive data model that appeals to applications where instant updates are critical. Supabase, conversely, positions itself as an open-source alternative to Firebase, providing a comprehensive backend-as-a-service with a strong emphasis on serverless PostgreSQL and integrated authentication. This difference is reflected in their community metrics, with Supabase boasting significantly higher GitHub stars and npm weekly downloads, indicating broader adoption across a wider range of general-purpose backend needs. Pricing models also present a key divergence. Convex's Professional plan is priced per developer at $25/month, which can scale up costs for growing teams, and its Business & Enterprise tier has a substantial $2,500 monthly minimum. Supabase offers a flat $25/month Pro plan, making its entry point more predictable for teams, and its Team plan is available at a more accessible $599/month. While Convex shows a slightly more frequent recent release cadence, Supabase's extensive feature set and community support often outweigh this for developers seeking a full-stack solution. Developers who prioritize a backend optimized for real-time synchronization and are comfortable with a per-developer pricing model should consider Convex. Supabase is the definitive choice for those requiring a robust, feature-rich BaaS built around PostgreSQL, complete with authentication and a thriving ecosystem, offering a more generalized and widely adopted platform for diverse application requirements.
