Nobody self-hosts a full Discord. What you can self-host is the 80 percent your community actually uses: text channels, roles, voice rooms, and calls — without an advertising-funded company scanning the lot. The honest framing is a three-way choice: Matrix for longevity and federation, Revolt for the familiar interface, Mumble when the community is really about voice.
You gain ownership of the social graph. Your community stops being one Trust & Safety decision away from deletion, messages can be end-to-end encrypted, and there's no Nitro upsell — useful when Nitro runs about $10 a month per enthusiast. On Matrix you additionally gain federation: users on other homeservers join your rooms without creating yet another account.
You give up network effects, and this is the loss that kills migrations. Everyone already has Discord installed; nobody has your Matrix homeserver. You give up polish too — screen-share quality, mobile notifications, and voice-channel UX all trail Discord — and you take on real operational weight: Synapse is rated Hard in our catalogue for a reason, wanting 1 GB of RAM plus Postgres before your first user signs in.
Communities planning to exist in ten years should take Matrix: Synapse as the homeserver, Element Web as the client (13,407 stars, easy to host, brandable), with Conduit as the lighter Rust homeserver that runs on a Raspberry Pi if Synapse feels like overkill. Communities that mostly want Discord-with-the-serial-numbers-filed-off should look at Revolt — servers, channels, roles, and an interface your members already understand, at the cost of a younger ecosystem. Gaming groups that live in voice should run Mumble: a 2005-vintage project with lower voice latency than Discord, a tiny server that idles in well under 128 MB, and a dated but functional client. Spacebar, which reimplements Discord's own API, is a fascinating project that I wouldn't yet bet a community on.
Discord offers no member-facing export of a server's message history, so your archives are effectively hostage; third-party exporter tools exist but sit against Discord's terms of service. Practically, you migrate people, not messages. The proven pattern is a bridge period — mautrix-discord mirrors channels between Discord and Matrix for months while stragglers move — followed by making the new home canonical. Expect to lose 20 to 40 percent of lurkers. Announce a date, pin the invite, and accept it.
Matrix with Synapse and Element for anything meant to last, because federation and an open protocol beat a prettier cage. If the pitch "it's Discord, but ours" is the only one your members will accept, Revolt.
