definitive-opensource

A definitive list of the best of everything open source

Status: Active - Projects: 209

Tip

Discussions and contributions are welcome! This project is in it's early stages and a lot hasn't been ironed out yet. Submit or make changes by forking this repo, editing, commiting, and opening a pull-request - or just raise an issue. For more information on contributing and guidelines for open-source software submissions, consult their respective pages.

Caution

We have a very rigorous vetting and research process. We continously monitor projects on the list and immediately remove projects that no longer fit the criteria.

Note

My MacOS configuration.

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.

• JetBrains - A suite of powerful (and slightly bloated) IDE's.
• Raycast - Incredibly powerful all-in-one utility.
