Most public projects on SourceHut (or anywhere else) need to have a software license before others can use the project, contribute to the code, and so on. Choosing the right license for your needs is important. If you're unsure of which to use, we can offer some suggestions.
Note: we are not your lawyer and this is not legal advice.
The Free Software Foundation publishes the GNU General Public License for this purpose. In short, it requires anyone who publishes modified versions of your code or software that uses it to publish their changes or the software they incorporated it into under the same license terms. Version 3 also requires hardware manufacturers to allow users to install their modifications onto devices which use GPLv3 licensed software.
Authors publishing software which is useful over a network — databases,
web applications, and so on — should consider the
Affero General Public
License, or AGPL, as well. The AGPL is similar to the GPL, but its terms also apply
when your software is used to provide a service over a network. Sourcehut itself is
distributed with the AGPLv3 license.
The MIT and BSD licenses allow anyone to use or modify your software for any purpose, including to make changes or incorporate it into their own software without releasing their source code. Both licenses are very short and easy to understand.
If you're publishing software as a business, Apache 2.0 is likely to be the most appropriate license for your open-source project. It explicitly protects your trademarks and includes a patent license for any patents which are applicable to your project.
