How we build software

  • On your own server

    Our products run self-hosted. Your data stays with you, and you decide when to update.

  • Signed updates

    Every release and plugin is cryptographically signed (Ed25519). Installs verify the signature before they apply anything.

  • One account for everything

    Licences, purchases and sign-in for every product in one place, with single sign-on and two-factor protection.

  • Made in Germany

    Built and operated in Offenbach am Main, hosted in Germany, GDPR-compliant.
