Effective Date: September 24, 2020
Timescale ultimately believes that open-source software produces higher-quality technology while providing transparency and flexibility to the developers that build on that technology. For these reasons, we are dedicated to developing TimescaleDB in the open and are making TimescaleDB available under the following licenses:
As of December 2018, we began categorizing features as Apache-2 or Community. Roughly speaking, as long as you are not offering TimescaleDB as a hosted Database-as-a-Service, you can use all Community features for free. For any questions, please contact [email protected].
