Is Convex worth the price?

80/100

Convex Free tier is generous for side projects: 1M function calls/mo and 0.5GB storage at no cost.

Professional at $25/dev/mo unlocks 25M function calls and 50GB storage with reasonable overage rates. The real value is the reactive backend, real-time sync, ACID transactions, and serverless functions in one package.

But costs can surprise at scale: database bandwidth at $0.20-0.22/GB and action compute at $0.30-0.33/GB-hr add up with heavy real-time workloads.

Hidden Costs & Gotchas

EU hosting adds a 30% surcharge on all usage, significant for European teams

Database bandwidth overage at $0.20-0.22/GB can spike with real-time sync patterns

Vector storage at $0.50-0.55/GB/mo is 2.5x the cost of regular database storage

Action compute at $0.30-0.33/GB-hr means long-running serverless functions get expensive fast
