Mattermost Licensing
|
||
|
||
SOFTWARE LICENSING
|
||
|
||
Mattermost server is made available under two separate licensing options:
|
||
|
||
- Free Software Foundation’s GNU AGPL v.3.0, subject to the exceptions outlined in this policy; or
|
||
- Commercial licenses available from SpinPunch, Inc. by contacting commercial@mattermost.com
|
||
|
||
Admin Tools and Configuration Files (model/, web/static/, web/templates/, web/react/utils/, api/templates/ and all
|
||
subdirectories thereof) are made available under:
|
||
|
||
- Apache License v2.0
|
||
|
||
LICENSING POLICY
|
||
|
||
The objective of the Mattermost server license is to require enhancements to Mattermost server be shared with the community
|
||
while allowing for non-enhanced use in proprietary applications.
|
||
|
||
Therefore, the Mattermost server is free to use, modify and redistribute in open source applications via the
|
||
copyleft AGPL license. For proprietary applications (systems that don’t share source back to the community),
|
||
Mattermost is free to use and redistribute so long as you’re not withholding proprietary enhancements to the
|
||
Mattermost server and you’re only linking directly to Admin Tools and Configuration Files (defined above), which
|
||
are released under an Apache 2.0 license, and copyleft free.
|
||
|
||
We promise that we will not enforce the copyleft provisions in AGPL v3.0 against you if your application (a) does
|
||
not link to the Mattermost server directly, but exclusively uses the Mattermost Admin Tools and Configuration files,
|
||
and (b) you have not modified, added to or adapted the source code of Mattermost in a way that results in the creation
|
||
of a “modified version” or “work based on” Mattermost as these terms are defined in the AGPL v3.0 license.
|
||
|
||
If the above is not enough to satisfy your organization’s legal department (some will not approve GPL in any form),
|
||
commercial licenses are available from commercial@mattermost.com.
