Here are some of the best open source alternatives to Discord as of 2026:

1. Rocket.Chat

  • A leading open-source alternative, offering real-time messaging, video calls, and file sharing. It’s highly customizable and suitable for teams of all sizes.

2. Element (Matrix)

  • Built on the Matrix protocol, Element provides end-to-end encrypted chat, voice, and video calls. It’s decentralized, supports federation, and is available on all major platforms.

3. Mattermost

  • Designed for developers and high-security environments, Mattermost integrates with tools like GitLab and Jenkins. It’s self-hostable and focuses on compliance and security.

4. Mumble

  • A privacy-first, open-source voice chat platform with ultra-low latency and encrypted communications. It’s ideal for real-time coordination and can be self-hosted on lightweight hardware.

5. Jami

  • Formerly Ring, Jami is a fully decentralized, peer-to-peer communication platform. It supports messaging, voice, and video calls with a strong focus on privacy.

6. Fluxer

  • An open-source (AGPL) platform based in Sweden, Fluxer is designed for privacy and self-hosting. It’s currently in active development and offers both free and enterprise options.

7. Stoat (née Revolt)

  • A free, open-source, user-first chat platform that recently rebranded. It aims to provide a community-driven alternative to Discord.

8. Zulip

Key Considerations

  • Self-hosting: Most of these platforms allow you to host your own server, giving you full control over your data.
  • Privacy: Many focus on end-to-end encryption and decentralized architectures.
  • Community & Features: Some are more mature (like Element and Rocket.Chat), while others are still evolving (like Fluxer and Stoat).

Would you like a deeper comparison of a specific platform, or are you looking for something tailored to a particular use case (e.g., gaming, business, or privacy)?
