Licences

A project needs a licence before it is public. Two questions get you to one.

Do you mind other people selling your work?

I do not mind - anyone may sell it
I do mind - nobody may sell it

Yes - changes must stay open
No - they may keep changes private

Answer both on the project settings page and it suggests one. You can ignore the suggestion and pick any of them.

The whole list.
Licence	In plain words
GPL v3 or later GPL-3.0-or-later	Anyone may sell it, but changes they share must stay open.
AGPL v3 or later AGPL-3.0-or-later	Like GPL, and it also covers running it as a web service.
MIT MIT	Do almost anything, including keeping changes private.
Apache 2.0 Apache-2.0	Like MIT, with a patent promise written in.
PolyForm Noncommercial PolyForm-Noncommercial-1.0.0	Source is open, but nobody may sell it or use it in a business.
Business Source Licence 1.1 BUSL-1.1	Source is open, commercial use waits a few years, then it turns open.

The licence is shown on your project page, and the source it covers is there to read and download. That is the point of the whole site.

Buildmorphic does not give legal advice. If the choice matters to your business, ask someone who does.
