The Verdict
Convex is built for full stack developers and real time apps, with a focus on real-time-database and serverless-functions. PostgreSQL targets backend developers and enterprises and leads with sql-queries and json-support.
PostgreSQL uses custom enterprise pricing, while Convex starts at $25/mo — a tangible advantage for teams with a fixed budget.
Both offer free plans, so you can test each with your real workflow before committing to a subscription.
Feature-wise, PostgreSQL offers broader built-in capabilities (8 features vs 6), while Convex takes a more focused approach — which can mean a simpler, faster onboarding experience.
Bottom line: PostgreSQL has a slight overall edge — but if real-time by default matters most to you, Convex may still be the right call.
