   Synapse (Matrix Homeserver)

   Self-host: Involved

   Reference Matrix homeserver powering decentralized, federated team chat

   4.5k Python AGPL-3.0 3 days ago

   How it compares to Discord

   • It is a backend only; you must pair it with a client (Element) for a usable product
   • Federation and database (PostgreSQL) tuning is required for scale and can be resource-intensive
   • Setup involves reverse proxy, TLS, well-known config, and federation ports
   • AGPL license and commercial relicensing have caused community friction

   Weechat

   Self-host: Involved

   Fast, extensible terminal IRC and chat client with a rich plugin ecosystem

   3.4k C GPL-3.0 4 days ago

   How it compares to Discord

   • Terminal-only; no native graphical UI, making onboarding difficult for non-technical users.
   • Third-party plugins are required for any non-IRC protocol, and plugin quality and maintenance vary.
   • No file sharing, image preview, video calls, or rich message formatting out of the box.
   • Configuration is fully text-based with a steep learning curve for advanced setups.

    Modern IRCv3 server in Go combining ircd, services framework, and bouncer

    3.3k Go MIT 8 days ago

    How it compares to Discord

    • IRC protocol only; no voice, video, reactions, or rich embeds expected by modern chat users.

    • Message history is limited and not searchable at scale compared to Slack's enterprise search.
    • No integrations with productivity tools (calendars, task managers, CI/CD) without external bridges.

    How it compares to Discord

    • No web or mobile app; all official clients are desktop-only with varying levels of polish

    • No team workspaces, channels, or role-based permissions
    • Bootstrap node setup and NAT traversal can be unreliable behind strict firewalls

    High-performance realtime server for WebSockets and Server-Sent Events

    2.4k Go MIT 6 days ago

    • It is a realtime transport layer, not a full chat product; requires significant custom development to build a user-facing app
