AGPL-3.0-ONLY

InspoSearch is licensed under the GNU Affero General Public License v3.0 (AGPL-3.0-only).

What This Means ​

The AGPL-3.0 is a strong copyleft license. The key distinction from the standard GPL is the network use clause: if you modify InspoSearch and make it available over a network (e.g. deploy a modified version as a web application), you must release your source code under the same license.

You Can ​

  • Use InspoSearch for any purpose
  • Study and modify the source code
  • Distribute copies
  • Deploy it on your own infrastructure

You Must ​

  • Include the original license and copyright notice
  • Disclose source code of any modifications
  • License modifications under AGPL-3.0
  • Make source available to users who interact with it over a network
  • State changes made to the code

You Cannot ​

  • Sublicense under a different license
  • Hold the authors liable
  • Use the project's trademarks

Network Use is Distribution ​

This is the critical clause of the AGPL. If you run a modified version of InspoSearch on a server and let users interact with it remotely, that counts as distribution. You must offer those users access to the corresponding source code.

This applies to:

  • Running a modified InspoSearch instance as a web service
  • Embedding InspoSearch search in another web application
  • Using InspoSearch as part of a SaaS platform
