You have probably watched a favorite app change direction over the years. Some of the most popular tools began life as open-source projects, with their code freely available for anyone to inspect, modify, and improve. But then something shifted. The developers decided to close the source code, moving to a proprietary model. This closed source migration can leave you feeling frustrated and uncertain about where to turn next. Fortunately, there are reliable open source replacements that keep the original spirit alive.
This article covers three well-known apps that took this path: Reddit, which kept its source code public for nearly a decade before locking it down; Emby, which grew from a community-driven Windows Media Center plugin called Media Browser into a closed platform; and a third popular service that followed a similar trajectory. For each one, you will find practical open source alternatives and free software replacements that respect your freedom and privacy. Understanding why these transitions happen helps you make smarter choices about the software you rely on every day.
Reddit → Lemmy
Reddit launched in 2005 as a simple link-sharing website, and in 2008 it released its source code as open source. That move made it a beacon for developers who valued transparency. But by 2017, Reddit stopped publicly maintaining its source code. The company still publishes numerous open-source tools today, but the platform itself has remained closed source ever since. For many users, that shift raised questions about control and community ownership. If you value the principles behind open source replacements, you might be looking for a platform where the code stays open and the community has a real say.
That’s where Lemmy comes in. Lemmy is a decentralized discussion platform that is the closest open-source Reddit alternative. Instead of one central server, Lemmy runs on a network of interconnected instances. You can join any instance or even host your own, and you can still interact with users across the entire network. This decentralized social media model gives you more freedom and prevents any single company from locking down the code or changing the rules. When comparing Lemmy vs Reddit, the key difference is ownership: Lemmy puts the community in control. If you want open source forum software that stays truly open, Lemmy is a practical, reliable choice. You can browse communities on topics from gaming to programming, all without worrying about the platform suddenly closing its doors.
Emby → Jellyfin
If you run a home media server, you have likely heard of Emby. It started life as Media Browser, a community-driven open-source plugin for Windows Media Center. In 2014 it was rebranded to Emby, and for years it remained a favorite for organizing and streaming your personal movie and music collection. But in 2018, things changed. Emby adopted a closed-source development model and switched to a freemium business model, meaning many advanced features now require a paid subscription. For users committed to keeping their media server fully open and free, this was a disappointing shift.
That is where Jellyfin comes in as one of the most practical open source replacements for Emby. Jellyfin is a direct fork of Emby, created by developers who wanted to preserve the original open-source vision. It offers the same core functionality — organizing your media, streaming to any device, and managing user profiles — without any paywalls. When comparing Jellyfin vs Emby, the biggest difference is that Jellyfin remains 100% free and transparent. If you are looking for media server alternatives that respect your freedom, Jellyfin is a reliable choice. It keeps the spirit of an open source media center alive, letting you host your own library with no strings attached. You can migrate your existing Emby library to Jellyfin with relative ease, and the active community ensures regular updates and plugins.
Finding More Open Source Replacements
If you have noticed, the pattern of apps ditching open source is not limited to Reddit and Emby. Many popular apps have taken a similar turn, leaving users searching for free alternatives. Fortunately, the open source community is resilient, and you can always find reliable open source replacements with the right approach. Tech journalists like Dibakar Ghosh specialize in uncovering these options. Ghosh, a writer at How-To Geek, focuses on Linux, Windows, and productivity tools, and his work has appeared on Authority Hacker. He started his career in 2016 with WordPress tutorials, so he knows the ins and outs of finding open source software. To discover your own replacements, start with community forums and comparison sites. Places like Reddit’s r/opensource or AlternativeTo.net are great for finding curated lists and user reviews. You can also search for how to find open source software or look up an open source alternatives guide to get started. The key is to be proactive and check community recommendations before committing to a new app. With a little digging, you will soon become adept at free software discovery and never feel stuck when a favorite tool changes direction.

Frequently Asked Questions
What are the open-source replacements for apps that went closed source?
Several reliable open-source replacements exist for apps that have abandoned their open-source roots. For example, you can use Lemmy as a decentralized alternative to Reddit, and Jellyfin serves as a fully open-source media server like Emby used to be. These free tools let you keep control over your data while avoiding proprietary lock-in.
What is the open-source alternative to Reddit?
Lemmy is the most popular open-source alternative to Reddit, offering a federated platform where you can create your own communities and moderate discussions. It works similarly to Reddit with upvotes, comments, and topic-based boards, but puts you in charge of the infrastructure. You can join existing instances or host your own for full privacy.
Are there other popular apps that went closed source?
Yes, several well-known apps have made the shift from open source to proprietary licensing over the years. Examples include the media server Emby, the code editor Atom (now discontinued), and the database tool MongoDB (which changed its license for certain uses). These moves highlight the importance of seeking out active open-source replacements before you commit to a new platform.
