Public work
Public integrations stay free and open source
A sponsored public integration becomes part of Endstate itself: open source under Apache 2.0, in the public module catalogue, and available to everyone at no cost. You are funding work that is given away, and the application’s other users benefit from it too.
Maintenance boundaries
What a completed sponsorship does not imply
A sponsorship is delivered work, not a maintenance commitment. When it is complete, the integration exists, is tested, and is documented. It does not come with lifetime maintenance, and applications change: a vendor can move a configuration file, restructure a settings format, or change package identity at any time, and a working integration can stop working through no fault of either side.
Ongoing compatibility guarantees are a different thing and require a separate agreement. If you need an integration to keep working against future releases, say so in your enquiry and we will scope that explicitly rather than leave it implied.
