FiloDB vs TDengine
Both stand on time-series databases. Which one you can start free with, which one lets you read the code, and what each costs once you pay.
Free plan APILinuxMac+1
Choose FiloDB if you need a self-managed, distributed time-series database for operational metrics, tracing, or real-time events and can work with its listed prerequisites. Look elsewhere for heavily transactional update-oriented workflows or OLAP and analytics, which the project identifies as anti-use-cases.
