License ​

Kizuna is free and open-source software licensed under the GNU Affero General Public License v3.0 (AGPLv3).

Copyright © 2025-present ItsAshn

What You Can Do ​

  • Use Kizuna for any purpose, including commercial use
  • Modify the source code to fit your needs
  • Distribute the original or modified software
  • Run Kizuna as a service on your own servers

What You Must Do ​

  • If you distribute Kizuna or a modified version, you must make the complete source code available under the same AGPLv3 license
  • If you run a modified version of Kizuna as a network service (e.g., a public chat server), you must make the source code available to anyone who interacts with that service
  • Include the original copyright notice and license text with any distribution

Why AGPLv3? ​

The AGPLv3 was chosen to ensure that all improvements to Kizuna remain free and open for everyone. If someone modifies Kizuna and offers it as a service, the AGPLv3 ensures their users also benefit from those modifications.

This is a stronger copyleft than the GPL or MIT — it closes the "ASP loophole" where companies could modify GPL software, run it as a service, and never release their changes.
