Voice chat room app source code on GitHub, honestly
Looking for voice chat room app source code on GitHub? The open source projects worth starting from, what clones leave out, and the parts that cost real time.
The short answer: if you want working source code for a voice chat room app, do not start from a "Clubhouse clone" repo. Start from a maintained open source media server and build your rooms on top of it. The usual starting points are LiveKit, Jitsi, mediasoup and Janus for the audio, and Mumble if you want a complete voice chat app you can run today. Search GitHub for those names, read the license file before you write a line, and expect the audio to be the easy part. The hard parts are moderation, identity, push notifications and keeping strangers safe, and no repo hands you those.
That is the honest answer. The rest of this post is why, from someone who went through it.
I built Hashti, a chat app with public voice and text rooms with names and topics. Hashti is not open source, so I am not going to point you at my code. I am going to point you at the projects I would look at if I were starting again, and tell you where I think people lose months.
What people mean by "voice chat room app"
When someone searches for this, they usually want one of three things:
1. A Clubhouse-style app. A room has a host, a few speakers and a lot of listeners. People raise a hand to speak. 2. A Discord-style voice channel. Everyone in the channel can talk. You drop in and out. 3. A group call. A small number of people, everyone on mic, often with video.
Under the hood, all three are the same technology. Each phone sends its audio to a server, and the server forwards it to everyone else. That server is called an SFU, a selective forwarding unit. The difference between the three app types is mostly rules: who is allowed to speak, who can join, who can remove someone.
So the first decision is not "which repo". It is "which media server", and then "how much of the app around it do I write myself".
The open source projects worth starting from
I am only listing projects that are well known and have been around for years. Check each one's GitHub page for its current license and activity before you commit. Licenses change, and I am describing them as I understand them, not giving legal advice.
LiveKit
LiveKit is an open source WebRTC media server with client SDKs for the web, iOS, Android, Flutter and React Native, among others. It is probably the fastest path from nothing to a working voice room in a mobile app. You run the server yourself or pay for their hosted cloud, and the SDKs handle the messy parts of connecting phones on bad networks.
My opinion: if you are building a mobile voice room app today and you are one or two developers, this is where I would start. The docs are good and the example apps are close to what most people want.
Jitsi
Jitsi Meet is a complete open source video conferencing app. It works in the browser and has mobile apps. If what you actually want is group calls, Jitsi gets you there with very little code, because the whole app already exists.
The trade-off is that Jitsi is built around meetings, not rooms. Turning it into a Clubhouse-style space with hosts, listeners and raised hands means fighting its design a bit.
mediasoup
mediasoup is a lower-level media server library for Node.js. It gives you the building blocks of an SFU and leaves the rest to you. That means more control and more work. People who pick mediasoup usually have a reason: they want their own signalling, their own scaling, or tight control over cost.
If you have never built a WebRTC app before, I would not start here. If you have, it is a solid choice.
Janus
Janus is a general purpose WebRTC server written in C, with plugins for different use cases, including an audio bridge for voice rooms. It has been used in production for a long time. Check its license carefully. As I understand it, it uses the GPL, which matters if you plan to ship closed source software built on it.
Mumble
Mumble is different from the others. It is not a toolkit. It is a finished, open source, low-latency voice chat app with a server and clients, long popular with gamers. If your real goal is "my group needs voice rooms" and not "I want to build a product", run a Mumble server and you are done tonight.
What about the Clubhouse clones?
When Clubhouse was big in 2021, a lot of clone repos appeared on GitHub. Some were impressive. Most were weekend projects, and many have not been touched in years. Before you fork any of them, look at three things on the repo page: when the last commit was, whether issues get answered, and what the license says. A clone with no license is not free to use, even though you can read it.
My opinion: clones are good for reading, to see how someone wired up raised hands or speaker lists. They are a bad foundation for a real app. Dependencies rot fast in mobile development, and you will spend your first month upgrading someone else's code instead of building yours.
What the source code will not give you
This is the part I wish someone had told me. Getting two phones to hear each other takes a weekend with any of the projects above. Getting strangers to use your app safely takes much longer. Here is the list of things no voice SDK solves.
Moderation
A voice room with strangers in it will, sooner or later, have someone saying something awful. Text can be filtered. Live audio is much harder. You need hosts who can mute and remove people, a way for listeners to report, and a person or a process that acts on those reports quickly.
You also need rules about who can speak in the first place. In Hashti, accounts that have not verified their identity cannot speak in voice rooms or host them. That is a product decision, not a code library. You can read more about how that works on how Hashti's safety rules work.
Identity and repeat offenders
If banning someone just means they make a new account with a new email, banning does nothing. Every open voice platform runs into this. Some use phone numbers, some use payment cards, some use document checks. Each choice has costs in money, in privacy and in how many people quit at sign-up.
Hashti checks identity once against a government document. The photo is deleted, a fingerprint of the document stays, so the same document cannot open a second account. Twelve verified reports close an account permanently. I am not saying that is the right answer for you. I am saying you need an answer, and it will not be in a GitHub repo.
Age and app store review
If your app lets strangers talk to each other, Apple and Google will look closely at it. You need a clear age rating, a way to report and block, and terms of use. Hashti is 18+. Decide early who your app is for, because it changes everything from sign-up to moderation.
Push notifications, background audio and real phones
Voice rooms on a phone have their own problems. What happens when the screen locks? When a phone call comes in? When the user switches from Wi-Fi to cellular in the middle of a sentence? When the user has Bluetooth headphones that connect half a second late? The SDKs handle a lot of this, but you will still spend real time testing on real devices.
Cost
Audio is cheaper than video, but forwarding audio to thousands of listeners is not free. Self-hosting saves money and costs time. Hosted services save time and cost money. Do the maths for your expected room sizes before you choose, not after your first busy night.
A sensible path if you are starting today
If I were starting a voice room app from scratch tomorrow, I would do it in this order:
1. Decide the room rules first. Who can join, who can speak, who can remove whom. Write them down in plain English. 2. Pick one media server. LiveKit if you want speed on mobile, Jitsi if you want group calls with little code, mediasoup or Janus if you want control and have WebRTC experience. 3. Build the smallest possible room. One host, speakers, listeners, raise hand, mute, remove. Nothing else. 4. Add reporting and blocking before you add anything fun. Not after launch. Before. 5. Test on cheap Android phones on bad connections. That is where your users will find the bugs. 6. Only then add the features you are excited about.
Most people do it in reverse, and I understand why. Features are fun. Moderation is not. But the apps that skip step four tend to have a short and unpleasant life.
When to not build it at all
Here is the honest part. If you want voice rooms for your own community, you probably should not build an app. Discord already does voice channels well. Mumble is free and runs anywhere. Telegram has voice chats in groups. Building and running a chat app is a long commitment, and the code is the smallest part of it.
Build your own if the product is the point: a specific audience, a specific set of rules, a reason that existing apps do not serve. That was my reason for Hashti. I wanted public rooms where people from different countries could talk, with identity checked once so that the same people could not keep coming back after a ban, and live translation across 29 languages for people who do not share one. No existing app did that combination the way I wanted, so I built it.
If you just want to see what a finished voice room app feels like before writing your own, Hashti is free on the App Store. Open a room, listen for ten minutes, and notice everything that is not audio: the reporting, the host controls, the rules about who can speak. That is the part you will be building for the next year.
Quick answers
Is there free voice chat room source code on GitHub? Yes. LiveKit, Jitsi, mediasoup, Janus and Mumble are all open source. Read each license before you use it in a commercial product.
Can I just fork a Clubhouse clone? You can, but check when it was last updated and whether it has a license. Most are better as examples than as foundations.
What language should I build in? Use whatever your team already knows. The media server can be separate from your app code, and every major SDK supports the common mobile frameworks.
What is the hardest part? In my experience, not the audio. It is moderation, identity and keeping a room pleasant when it is full of strangers.
Hashti is free, and it is 18+. Hashti Plus — live translation, writing help and catch-ups — is $4.99 a month or $39.99 a year, and nothing else costs anything. How rooms work is on the rooms page, and how reports and the ID check work is on the safety page.
