Rebex

Rebex (Rebex CR s.r.o.) is a Czech publisher of .NET libraries for SFTP, FTP, SSH, TLS, HTTPS and e-mail protocols, plus the Buru SFTP Server. Its .NET components are sold as perpetual per-developer licences with royalty-free runtime redistribution.

Licensing at a Glance

  • Perpetual licence
  • Named user

  1. The Rebex General End User Agreement grants a limited, perpetual, non-exclusive, non-transferable licence to the .NET components, and allows the licensee to distribute the runtime with its own products royalty-free.[1]

  2. Under the single developer licence, every developer working with the Rebex product on a project must purchase a licence.[2]

  3. Rebex .NET libraries are licensed per developer; testers who only use the compiled application and automated build servers do not need a licence, and a licensed developer may use the library on any number of machines.[3]

  4. A licence can be reassigned to another developer when the original developer leaves or no longer needs access, and a library pack licence cannot be split between several developers.[4]

  5. Trial copies may be used for evaluation only for 30 days, may not be used to create applications and may not be redistributed.[5]

  6. Rebex libraries may not be used in a product that directly or indirectly competes with them, such as a repackaged component or wrapper that exposes the Rebex API to other developers.[6]
