Open-source apps that replace Reddit
Lemmy is a link-sharing and forum site where people subscribe to communities, post links and discussions, and vote on them. It is for people who want a Reddit-style forum that anyone can host on their own server and that connects to other servers in the Fediverse.
Mbin is a decentralized platform for posting links, voting and discussing topics, and sharing short posts. It is built for people who want a Reddit-style community that connects to the fediverse.
PieFed is a federated discussion and link-sharing platform, similar to Reddit, that works with other Lemmy and Mbin sites. It is built for people who want to run or join communities without relying on a single company.
Discourse is a forum software for running online communities where members create discussion topics, chat in real time, and reply to each other. It is for community owners who want to host their own site or use official hosting.

Fix the list itself
A project or closed app missing from this list, or a mistake on it? These open a short form on GitHub, and a mod reviews it. To say what a project can't do, use What's missing.
About this page
Replaces fully means it does the main job of these apps; Replaces partly means it covers some of it.
Licenses: every project here uses an open-source license (what each one means). Open core means some parts are paid or under another license.
GitHub stars are shown for reference. They measure popularity, not whether it replaces anything.
Verified means r/TrueOpenSource mods checked it: open-source license, maintained, and it really does the job.
