Is QuestDB worth the price?

Good value

QuestDB offers a very generous freemium model with its Open Source tier at $0, providing a high-performance core engine for basic needs.

The Enterprise tier, with its undisclosed pricing, is likely expensive but offers critical features for large-scale, high-availability deployments. This structure is best for individual developers or small teams starting out, and large enterprises requiring robust, scalable solutions.
