Discord solved real-time community better than almost anyone: instant voice, organized channels, roles, and one-click invites made it the default home for game clans, study groups, and open source projects alike. The catch is whose house you are gathering in. Your server, its entire message history, and the relationships built inside it all live on Discord's infrastructure under Discord's terms, so a moderation call, a feature change, or a shift in the platform's business model happens above your head. The open source alternatives below recreate the channels-and-communities model on servers you run, so the conversation history and member data sit on infrastructure you control and no outside policy change can lock you out of the space you built.
Discourse is an open-source community platform for running discussion forums on infrastructure you control. You create discussion topics to organize conversation, giving a community a single online home, with an optional hosted service if you would rather not manage your own server.
NodeBB is forum software powered by Node.js for building discussion communities on the web. It keeps the bulletin board model of categorical hierarchies, local user accounts, and asynchronous messaging, while adding real-time streaming discussions, mobile responsiveness, and rich RESTful read and write APIs.
Element is a Matrix web and desktop client for secure messaging and collaboration. It connects people on the open Matrix network and can be self-hosted or used through Element Matrix Services, giving organizations a choice of where their data lives.
SimpleX Chat is a private and encrypted messenger for people who want to communicate without user identifiers of any kind, not even random ones. It protects messages and metadata, including who you talk to and when, and lets you make a private connection before any messaging starts.
Stoat is an open source chat app for friends and communities, in the style of Discord. It centers on servers and channels where groups can talk in real time, with customization as a core theme of the project.
Vanilla is open source forum software for building community discussions that you can customize to fit the group using them. It has powered tens of thousands of community forums, and is built so designers and developers can craft an environment tailored to a community's particular needs.
Quiet is a private team chat app for groups that do not want a central server. It is an alternative to Slack, Discord, and Element, and it syncs data directly between team devices over Tor with no server required.
Spacebar is an open source reimplementation and extension of the Discord backend. It lets you run a Discord-compatible chat server on infrastructure you control, staying backwards compatible with existing bots, applications, and clients while adding features of its own.
Twake is a secure open source collaboration platform built to improve how organizations work together. It brings team chat, file storage, a shared team calendar, task management, video calls, and real-time document collaboration into a single digital workplace.
Delta Chat is a decentralized, secure messenger that delivers chats over the email network. Instead of a proprietary server, it can sign up to interoperable chatmail relays, so your messages travel like email but stay end-to-end encrypted.
Open Source Social Network (OSSN) is social networking software written in PHP for running your own community site. It gives members user profiles, friend connections, and a shared space to post, share interests, and form relationships, with support for more than 20 languages to reach a global audience.
Wire is a secure messenger built for organizations and trusted by millions of people worldwide. It is designed around end-to-end encryption, so message content stays protected and collaboration happens without compromising on privacy.
Session is a private messenger for Android that aims to remove any chance of metadata collection. It routes all messages through an onion routing network that obfuscates users' IP addresses, so you can talk without handing over a phone number, an email, or the connection details that usually trail a conversation.
Briar is a messaging app for activists, journalists, and anyone who needs a safe way to communicate. It does not rely on a central server, so messages sync directly between users' devices instead of through a hosted service.
Jami is a distributed, open source communication platform. Rather than routing conversations through a central service, it is built as a distributed system, which keeps communication in the hands of the people using it.
Which alternative fits depends on whether you want a familiar Discord-style home, compatibility with your existing bots, or no central server at all.
Best for a familiar self-hosted community: Stoat Stoat carries on the Revolt project as a Discord-style chat built around servers and channels, with real-time messaging on a Rust backend using MongoDB and Redis. You can run the whole stack yourself through Docker, which keeps a community's data off a hosted platform. It suits groups that want Discord's shape and feel without handing control of their history to a third party.
Best for keeping existing bots and clients: Spacebar Spacebar reimplements the Discord backend so that many bots, apps, and clients built for Discord.com can connect to a server you host, bundling an API, gateway, CDN, and WebRTC voice server. Because it reverse-engineers the API rather than reusing it, some clients will not connect cleanly, so test yours first. It fits teams whose bot and integration investment is too large to rebuild from scratch.
Best for a serverless private group: Quiet Quiet takes the opposite approach, syncing messages, files, and membership directly between member devices over Tor with no central server, and encrypting everything end to end. It is early software and not yet audited, so it fits small, security-minded groups comfortable with rough edges more than large public communities.
The hardest thing to move off Discord is not the software but the community itself, and how much of it you can carry with you. Discord offers no complete server export that recreates channels, roles, threads, reactions, and permissions somewhere else, so a switch is mostly a rebuild. That makes the architecture choice the real decision. Stoat, a continuation of Revolt, gives you the closest thing to a familiar Discord-style server you host yourself, with servers, channels, and real-time chat on a Rust backend you run through Docker.
If keeping your existing bots and integrations matters more than a fresh start, Spacebar takes a different route: it reimplements the Discord backend so that many clients and bots built for Discord.com can connect to a server you control. Because it reverse-engineers the API rather than reusing it, some clients will not connect cleanly, so test your specific bots early. For a small, private group that wants no server at all, Quiet syncs directly between member devices over Tor, though it is early software and not yet audited, so weigh that against your security needs.
Whichever you pick, plan the human side as carefully as the technical one. Build the new channel structure first, remap roles by hand, archive the announcements and threads worth keeping, and move bots one integration at a time. Run both communities briefly while you redirect invites and set a clear cutoff date, and test mobile push on real devices, because that is where members feel the difference first.
Not fully. Discord does not provide a server export that recreates channels, roles, threads, reactions, attachments, and permissions in another system. Individual members can request their own account data, but that is not a portable community archive. Most migrations preserve selected announcements, rules, docs, and high-value threads through manual exports or API tools where allowed, then start regular discussion fresh in the new space.
Voice quality varies far more than text chat between projects, so test it under the conditions your community actually uses - the same number of people, devices, and network quality. Watch echo cancellation, reconnect behavior, mobile backgrounding, and screen-share frame rate. A tool that feels fine in a small meeting can struggle during a large game night or public event if it was not sized for real-time media.
Inventory every bot and webhook before choosing, and separate simple notifications from workflows that assign roles, mirror commits, or run events. Spacebar is built for exactly this case: it stays backward compatible with many Discord bots and clients, so integrations can connect to a server you host. Because it reimplements the API, some will not work cleanly, so test your specific bots rather than assuming they all carry over.
Do not assume they are until you test on real iOS and Android devices. Discord has trained communities to expect fast push alerts, easy replies, and reliable presence. Open source clients may rely on different push gateways or background behavior, especially when self-hosted. Check mentions, direct messages, muted rooms, uploads, voice join flows, and battery impact before moving the main community over.
Not always, but self-hosting is usually the point. Stoat and Spacebar are designed to run on your own infrastructure through Docker, which is what puts retention, domains, and moderation policy in your hands. Quiet skips servers entirely by syncing between member devices. Self-hosting makes uptime, backups, and patching your job, so if no admin wants that work, a managed deployment of an open source system is the more realistic path.
Plan to remap them by hand. Discord roles often bundle identity, channel access, moderation power, cosmetic labels, and notification habits into one thing, and other systems separate those concepts or handle inheritance differently. Before inviting everyone, create test accounts for owner, moderator, regular member, and guest, then verify private channels, invite controls, message deletion, and audit logs behave the way your community expects.
