A definitive list of the best of everything open source
Status: Active - Projects: 299
Why another list?
There's plenty of awesome lists on GitHub, many focusing on open source specifically. However I've found them including many long-deprecated apps, cluttered with smaller projects on the verge of extinction, or missing a lot of modern open source projects.
This list aims to be comprehensive and highly curated, consolidating only the best open source projects. Mostly apps with a solid user base, solid set of contributors, and visible long term growth are included. These criteria are nothing more than suggestions, however, and projects with potential or ones that set out on a unique path can bypass the above criteria.

FAQ
How about a JSON file with a script that generates the readme?
I’ve given this a lot of thought. Such a system would make fundamental changes and reorganization far easier whilst minimizing formatting and grammatical errors.
However, for the foreseeable future, the list will continue to be edited directly as a markdown file. This is for one main reason: to keep everything simple. I will likely change my stance on this later as the project scales and when I have time to architect such a system. Although it can be tedious, the current system will have to suffice.
How about a website, perhaps an automated one?
I’ve considered making a website, one with features like filtering with tags or even an automated system that scans github repositories and categorizes them. The problem is that it wouldn't be much different from other tools out there like openalternative or trendshift and an automated system will always have shortcomings. The point of definitive-opensource is to be highly curated, and the current best execution of that is in a readme. I’m a busy college student and the complexities of web development seem unnecessary and an added pain for a task that can suffice, for now, as a markdown file.
