Source: https://tdengine.com
What platforms does TDengine support?
TDengine supports macOS, Linux and a command-line interface. Platforms we have not confirmed are simply not listed here rather than ruled out.
Can TDengine be self-hosted?
Yes. TDengine can be deployed cloud / SaaS, hybrid and self-hosted, so it does not have to run on the vendor's infrastructure.
What does TDengine integrate with?
We have confirmed 3 integrations for TDengine, including Java, Python and Go. This is what we could verify from public sources, so the vendor may support others we have not indexed.
What security certifications does TDengine have?
We have independently confirmed SOC 2 and ISO 27001 for TDengine. Certifications we do not list are ones we have not been able to verify from public sources, which is not the same as TDengine not holding them. Always confirm compliance directly before you rely on it.
Source: https://tdengine.com
Is TDengine open source?
Yes. TDengine is published under the AGPL-3.0 licence, a copyleft licence, so check its terms before embedding it in a closed-source product. Licence terms can change between releases, so verify against the repository for the version you intend to use.

The vioscaleAI score: one lens on the evidence
Not user reviews and not a paid placement: a confidence-weighted blend of the independent signals below (adoption, activity, security posture, and more), which you can sort and re-weight yourself. Vendors can correct their listing but can never move their rank, and stars are weighted low as a vanity metric. It is one way to read the evidence for TDengine, not the verdict.
