Do we need a commercial license for self-hosted Discourse?

We want to use discourse as a community portal in our commercial application.

Investigated - Its open source with GNU GPL licence.

Do we need commercial license for self-hosted discourse, if we need to include that in our commercial application.?

If yes, can anyone please provide the details regarding the license + support cost.?

You do not need to pay to use the software. You do need to pay for support (unless you can get it here). See and the FAQ section of If you need support for a self hosted installation there are people like me who can help. (post in #marketplace or find my contact info in my profile).
