Open source

The shoulders we stand on, and the ones we lift.

Software is a supply chain. We publish what we can, sponsor what we use, and document every dependency that touches production.

Every production release ships a signed CycloneDX SBOM. Customers under NDA can subscribe to the SBOM RSS feed and receive notifications whenever a dependency version, license or CVE status changes.
