# Commercial support

As every Apache project, so is `Apache IoTDB` generally available and usable by anyone free of charge.

Also does the `Apache IoTDB Community` offer free support on the official project `Mailinglist`. This support is however, done voluntarily by the community, so there are no service-level-agreements, guaranteed reaction times or guarantee that an issue will be addressed or solved.

If you or your business has higher demands on guaranteed availability and execution of support requests, the following individuals and companies have commercial support offerings.

The information provided here was provided by the entities named, and is not verified (except the `Involvement Level`), updated or endorsed by the `Apache Software Foundation` or the `Apache IoTDB` project.
