DatabaseSupabase vs Convex (2026): Which Is Better?
Supabase and Convex are both popular choices, but they serve different needs. Supabase is a Database with a traditional, manual approach to building, while Convex is a Database that prioritises developer or designer control.
Below you'll find a side-by-side breakdown of detection signals, AI scores, and technical fingerprints — plus our honest take on which builder wins for different use cases.

Supabase
Database
Supabase is a database with an AI Score of 10/100 (Unknown). Our detection engine uses 5 signal patterns to identify Supabase-built sites.
Convex
Database
Convex is a database with an AI Score of 10/100 (Unknown). Our detection engine uses 4 signal patterns to identify Convex-built sites.
Platform Overviews
Supabase
Supabase is an open-source Firebase alternative built on Postgres, bundling a database, authentication, storage, and real-time subscriptions into one developer platform — widely adopted because it gives teams a full Postgres database (rather than Firebase's NoSQL model) with a similarly fast setup experience. Our engine detects Supabase through 2 script patterns, 2 HTML patterns, and 1 CDN domain tied to its client SDK's API-request conventions and asset delivery. Supabase can be self-hosted or used via its managed cloud; detection doesn't distinguish between the two. Documented at supabase.com.
Convex
Convex is a hosted backend platform combining a reactive database, serverless functions, and real-time subscriptions in one TypeScript-native product, positioned as a more integrated alternative to assembling Postgres, a queue, and WebSockets separately — popular for real-time collaborative apps. Our engine detects Convex through 2 script patterns and 2 HTML patterns tied to its client SDK's real-time connection handling. As a fully managed backend, a detection confirms a live integration with Convex's hosted infrastructure. Documented at convex.dev.
Key Differences
- Both Supabase and Convex are classified as Database tools, making them the most direct competitors in this comparison.
- Supabase scores higher on AI involvement (10/100 vs 10/100 for Convex), meaning it relies more heavily on AI for site generation and content creation.
- Our detection engine identifies Supabase using 5 fingerprint patterns and Convex using 4 patterns — more signals generally means more reliable detection.
Which Should You Choose?
Choose Supabase if…
