Questions about Convex
What is Convex?
Convex is a reactive backend for apps and agents, available on the web and through an API. Automatic caching and scaling keep data up to date in real time across users, built-in type checking catches errors before deployment, and modular TypeScript components make integration easier.
How much does Convex cost?
Convex starts at $0 per month on a limited free tier with pay-as-you-go pricing. The paid plan starts at $25 per month, and the reviewer notes that premium pricing for larger teams starts at a $2,500 monthly minimum.
Does Convex support SQL?
No. Convex lacks traditional SQL features and has no relational database support, which the reviewer lists as a shortcoming. The reviewer advises anyone who needs relational databases to avoid it, and Toolio lists large SQL-dependent enterprises among those it does not suit.
Can Convex be self-hosted?
Self-hosting Convex requires premium plans, and the reviewer says those plans come with limited capabilities. Convex also offers sandboxed open-source components that developers can use as building blocks in their own projects.
What are some alternatives to Convex?
Toolio lists Onetab AI, Clawbot and Modal as alternatives to Convex. Modal deploys AI models with sub-second cold starts and runs them on any GPU, while Onetab AI centralizes AI agents in one channel but lacks complex integrations.
