This repository contains the core source code that powers the entire suite, maintained by nearly 3,000 contributors.

why it matters: For builders and organizations, LibreOffice represents a proven, enterprise-grade productivity platform that can be embedded, extended, or self-hosted without licensing costs — a strategic alternative to paying for Microsoft 365 at scale.

Jellyfin Web is the official browser-based interface for Jellyfin, a free, self-hosted media server that lets people stream their own movies, TV shows, and music — similar to Netflix or Plex, but without any subscription fees or corporate ownership. It powers the user-facing experience across web browsers, Android, and iOS apps, making it the primary way most users interact with their personal media libraries.

why it matters: With over 3,400 stars and nearly 2,800 contributors, Jellyfin represents a rapidly growing open-source alternative to paid streaming infrastructure, signaling strong consumer demand for privacy-first, self-hosted media solutions. For builders, it offers a proven, freely reusable foundation for any product involving media streaming, content delivery, or subscription-free entertainment platforms.

Audacity is a free, open-source audio recording and editing tool that works on Windows, Mac, and Linux, letting users record, cut, mix, and enhance sound files. It's one of the most widely used audio editors in the world, and the team is currently rebuilding it from the ground up with a completely new interface as version 4.

why it matters: With nearly 20,000 stars and a massive global user base, Audacity represents the dominant open-source alternative to expensive professional audio software — making it a key reference point for any team building audio-related products or tools. The ongoing v4 rebuild signals a major modernization effort, which could open new integration opportunities or raise the competitive bar for startups in the audio creation and podcasting space.

B1Admin is a free, open-source software platform that helps churches manage their members, track attendance, coordinate groups, and handle donation records — essentially an all-in-one administrative hub for religious organizations. It can be run on a church's own servers or deployed instantly through managed hosting, giving organizations full control over their data.

why it matters: With 150 stars, 68 forks, and 30 contributors, this project signals real demand for affordable alternatives to expensive church management platforms like Planning Center, which can cost thousands annually — a market covering hundreds of thousands of congregations worldwide. For founders, it validates a self-hosted, community-funded open-source model as a viable strategy to compete against established SaaS players in vertical-specific software markets.
