## Open source stays open source

TerminusDB is open source under the Apache 2.0 license. The community version keeps getting releases and security patches. You can run it yourself for free with [Docker](/docs/install-terminusdb-as-a-docker-container/).

For production, managed hosting and TerminusDB Enterprise are available through [TerminusDB Cloud](/docs/cloud/) and [Azure](/docs/deploy-on-azure/).

## How Gettier uses TerminusDB

Gettier builds a platform for finance teams, from record to report, where every number is traced to its source. TerminusDB is the open-source foundation under it.

Financial reporting needs the same things TerminusDB is built for:

- **Every change is tracked.** You can see who changed a value, when, and in which commit.
- **Data is checked before it counts.** The schema checks every document when it is written.
- **History is kept.** You can go back to any earlier commit and compare it with today.
