TurnFix Licensing

License: GNU Affero General Public License v3.0 (AGPL-3.0)
Copyright: © 2025 Dominik Prudlo
Point: 50

License Choice: AGPL-3.0

TurnFix uses the AGPL-3.0 license. This was chosen because:

  1. Copyleft: All modifications must be shared as open source under the same license
  2. Network Clause: Since TurnFix is a web application, the AGPL's network clause (Section 13) ensures that users accessing TurnFix over a network also have the right to receive the source code — even if TurnFix is only hosted (not distributed as a binary)
  3. Open Source Requirement: Anyone modifying, improving, extending, or fixing bugs must make those changes available as open source

Key AGPL-3.0 Obligations

Obligation Description
Source code access Users (including network users) must be able to access the source code
Copyleft Derivative works must also be AGPL-3.0
Attribution Original copyright notice must be preserved
State changes Modifications must be clearly marked
No additional restrictions Cannot add further restrictions beyond AGPL-3.0
