<p align="center"> A definitive list of the best of everything open source</p>

<p align="center"><code>Status: Incremental</code> - <code>License: MIT</code></p>

> [!NOTE]  
> This project is currently in the alpha stage. The list is currently edited directly from the readme, however my goal for the 1.0 release is for all open-source projects to be under a "list.json" file with scripts that automatically generate the readme. This would automate organization and make re-ordering far easier whilst enabling API retrieval of repository stats for always up to date star counts and descriptions. Consult the roadmap for further information regarding development.

> [!TIP]  
> Submit or make changes by forking this repo, editing, commiting, and opening a pull-request. For more information on contributing and guidelines for open-source software submissions, consult their respective pages. 

> [!CAUTION]  
> Starcounts are hard-coded and may not reflect latest values. API retrieval system of stars planned for 1.0 release.

## 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, including only the best open source projects. This is, to some extent, guaged with popularity. Only projects with over 5000 stars are generally included, however there can be exceptions. There's plenty of extraordinary projects with just a couple thousand stars.
Guaging the quality of software based on popularity alone is not the best way, I do admit, but to keep this list functioning at scale it is the most reliable method.

## Honorable Mentions of Closed-Source Software
Although a rare occurence, there are times in which proprietary software is the best option available even amongst closed-source competitors. Here are several such applications that deserve a spot on this list.
- [Davinci Resolve](https://www.blackmagicdesign.com/products/davinciresolve) - A full-fledged video editor with a powerful free tier. 
- [Obsidian](https://obsidian.md/) - One of the most popular note taking apps / markdown editors. Almost everything about this project screams open source, except for the fact that it's not open source (like no analytics, free unless you want sync, and local storage).
- [LM Studio](https://lmstudio.ai/) - Feature rich gui for running local LLM models.
- [JetBrains](https://www.jetbrains.com/) - A suite of powerful (and slightly bloated) IDE's.
- [Raycast](https://www.raycast.com/) - Incredibly powerful all-in-one utility.
