15 Best Open Source Discord Alternatives 2023

Keeping in touch has never been more important for teams of all sizes. This is especially true with the work from home or work from anywhere approaches, which businesses have had to adopt in these unprecedented times.

However, when it comes to picking the best communication tools for your team or business needs, it’s probably more confusing to find the one that checks all the boxes.

There’s a whole slew of team messaging and video conferencing options available, making it harder to tell what will work for your specific team or business setup.

Discord is just one of the many messaging services that rose to popularity thanks to the gamer community. The platform organizes conversations into channels by topic with options for text, voice, and video chat too.

While businesses are looking into using Discord for their own teams, there are a few issues with the platform that make it less desirable.

For instance, the interface may not be intuitive for non-gamer members of your team, file sharing is limited depending on the pricing plan, and the platform was designed for gaming, not business or professional use.

On top of that, Discord may not have a professional look and feel for your team or for use with clients and other external guests on messaging threads or calls.

Here’s a rundown of the 15 best open-source Discord alternatives you can check out and find one that’s right for your team.

Best Open-Source Discord Alternatives

1. Element

Element is an end-to-end encrypted (E2EE), secure messaging and collaboration app that’s based on Matrix. The tool provides voice and video calls, instant messaging, file and screen sharing, and huge chat rooms for one-on-one communication.

You can use it on any platform including Windows, macOS, Linux, and mobile devices to enhance communication and collaboration.

While Discord is basically free and ideal for small teams and businesses, Element is open-source and completely free but designed with governments, communities, and companies seeking digital sovereignty.

Plus, Discord doesn’t offer official integrations and moderators aren’t in control as much as they would be with other messaging platforms.

Element has a decentralized design for digital sovereignty, and you can deploy it on-premises or through a cloud provider.

Plus, Element provides a SaaS version of its platform through Element Matrix Services, which provides enterprise-grade add-ons and fast performance.

As a Matrix-based software, Element can bridge into Slack, Discord, Telegram, and Teams. This way, it’s easier to connect between organizations, and still keep your files and conversations safe using E2EE encryption.

The universal secure chat application can be self-hosted, giving you more control over your data, and you can still organize rooms around any topic, add widgets, share files, and more. You can also use QR codes or emoji comparisons to safeguard against eavesdroppers and imposters.

2. Mattermost

Mattermost is another open-source platform that enables communication and team collaboration.

The messaging platform gives you peace of mind because you don’t have to worry about data privacy or security, and you get full control over your data unlike with Discord, which doesn’t give moderators as much control especially over direct messages.

Plus, Mattermost is self-hosted while Discord isn’t, and you get better support for Markdown and LaTex, as well as message threads on Mattermost.

The software isn’t just open-source but flexible and enables secure team collaboration. This way, you can collaborate across large teams and build intuitive workflows that scale to tens of thousands of concurrent users.

DevOps teams can also use Mattermost to power collaboration at each step of the lifecycle. Mattermost also unifies tools, people, data, and automation to help teams increase agility and innovation.

The open-source tool allows you to integrate your favorite tools, automate work and configure its design to your liking. In addition, Mattermost is written in React and Golang, runs a single Linux binary with PostgreSQL and MySQL, and offers file sharing, which Discord lacks.

You also get real-time group chat or webhooks and you can use other features you like while accessing the software’s source code.

3. Jitsi

Jitsi is an open-source and completely free project that lets you build video conferencing solutions for your team or business.

Unlike Discord, which is an all-in-one voice and text chat built for gamers, Jitsi is a multi-platform open-source platform for video conferencing that’s completely free to use and makes it easy to build and deploy video conferencing solutions.

Jitsi takes video calls to the next level, works on web and mobile devices, and supports advanced video routing concepts such as scalable video coding and bandwidth estimations.

The software lets you have conferences on the web while other projects enable other features including recording, dial-in, audio, and simulcasting.

Jitsi’s text chatting is only available for the web though, but you get more features like screen sharing, locking rooms with passwords, and streaming a conference to YouTube live with Jitsi.

Unlike Discord, which doesn’t offer file sharing, you can share text documents on Jitsi based on Etherpad, raise or lower your hand for attention, and view participant talk-time stats.

4. Jami

Jami, formerly Ring, is an open-source Discord alternative that prioritizes privacy and facilitates direct calls between its users.

The software has a professional-looking design and works on all major platforms, including Windows, Mac, and mobile apps on Android and iOS devices.

While it’s not as fully featured as other Discord alternatives on this list, Jami provides a good selection of tools such as HD video calling, voice and instant messaging, and file sharing, which you won’t get with Discord.

Plus, Jami is decentralized in nature, meaning the calls are only between you and your recipient, so nobody else can see or hear your conversation. Jami doesn’t use servers to handle calls, meaning you get to enjoy even greater privacy.

You can share your live gameplay with other users as you would on Discord, create multiple groups or teams to communicate with, conduct private group meetings or sessions, and share your screen.

You can also send and receive text messages or record your gameplay and communication simultaneously.

5. Mumble

Mumble is an open-source and completely free, high-quality, low latency voice chat app. The app, which was established more than a decade ago, was the first VoIP app to establish true low latency voice communication, but it can also be used for recording podcasts.

Like Discord, Mumble was designed with gamers in mind, but a variety of workplaces adapt the app to fit their needs whether communicating across countries, on-head mobile devices, or into airplanes.

The software can be used with games for real-time voice communication, and has servers globally, meaning you can specify servers that are closer to you and get the best experience.

Mumble is quite different from Discord as it allows chat encryption if you value your privacy, has impressive voice quality with positional sound features, and works on all platforms.

While Mumble lacks browser support, which Discord users are fond of, you still get in-game overlay, real-time voice communication for teams and other users, plus privacy and security. In addition, up to 100 participants can communicate in real-time with each other on Mumble.

Mumble is built differently depending on each kind of user, with specific features for end-users, administrators, and hosters.

6. qTox

qTox is an open-source messaging platform that’s big on privacy. The Discord alternative works with Windows, Mac, Linux, FreeBSD, and other platforms, offering many similar features including video and voice communication, group communication, and text chat among others.

qTox offers leading class encryption so that the messages you send only reach the people they’re meant to be sent to. Plus, it’s designed for any user, not just gamers like Discord was built for, and it’s easy to use so you can focus on your conversations.

The tool is easy to use and modify, plus, you don’t get pesky ads all over the platform while chatting or video calling. You also don’t have to pay for some features like Discord makes you do to get upgraded features with its Nitro package.

qTox also offers file sharing, which Discord lacks, so you can send and receive files and documents, screen share, and create your own avatars.

7. Telegram

Telegram is an instant, free messaging app that’s easy to use, secure, and is feature-rich. The open-source app is available across desktop and mobile devices, which makes it one of the most popular open-source Discord alternatives available.

You get heavily encrypted messages, some of which can self-destruct, the ability to hold groups of up to 200,000 members, share media and chats with no size limits, and has fast message delivery.

You can also share files, which Discord doesn’t do, and customize the messenger to your liking.

What makes Telegram different from Discord is that while the former is focused on speed and security, Discord is designed for easier organization of communication, and not user privacy.

Plus, Telegram allows file sharing, which includes pictures, executable files, gifs, and videos, while Discord is a modern voice and text chatting app.

Moreover, Discord is closed-source as it’s built from proprietary software, while Telegram is open-source and offers all its features for free. Discord on the other hand offers some of its advanced features in its premium Nitro plan.

8. Rocket.Chat

Matrix is Apache-licensed and is suitable for powering VoIP, IoT, internet messaging, and WebRTC signaling along with any other app that requires a standard HTTP API to publish or subscribe to data.
