We all love open-source software, but there are so many amazing projects out there that often go unnoticed. Let’s change that! Share your favorite open-source software that you think more people should know about. Here’s how you can contribute:
- Single Option Per Comment: Mention one open-source software per comment to be able to easily find the most popular software.
- No Duplicates: Avoid duplicating software that has already been mentioned to ensure a wide variety of options.
- Upvote What You Love: If you see a software that you also appreciate, upvote it to help others discover it more easily.
