mkipcak / neko

A self hosted virtual browser (rabb.it clone) that runs in docker.

n.eko

This app uses Web RTC to stream a desktop inside of a docker container, I made this because rabb.it went under and my internet can't handle streaming and discord keeps crashing when my friend attempts to. I just want to watch anime with my friends ლ(ಠ益ಠლ) so I started digging throughout the internet and found a few kinda clones, but none of them had the virtual browser, then I found Turtus and I was able to figure out the rest. This is by no means a fully featured clone of rabbit, it hs only one room. It's stateless, so no saved user names or passwords.

Features

• Text Chat (With basic markdown support, discord flavor)
• Admin users (Kick, Ban & Force Give/Release Controls)
• Clipboard synchronization (on supported browsers)
• Emote overlay
• Ignore user (chat and emotes)
• Settings are saved to local storage

Why n.eko?

I like cats 🐱 (Neko is the Japanese word for cat), I'm a weeb/nerd

But why the cat butt? Because cats are assholes, but you love them anyways.

Super easy mode setup

1. Deploy a server or VPS

   Recommended Specs:

   Resolution	Cores	Ram	Recommendation
   576p	2	2gb	Not Recommended
   720p	4	4gb	Good Performance
   720p	6	4-6gb	Recommended
   720p+	8	8gb+	Best Performance

   Why are the specs so high? : If you think about it, you have to run a full desktop, a browser (a resource hog on its own) and encode/transmit the desktop, there's a lot going on and so it demands some power.

2. Login via SSH

3. Install Docker

   curl -sSL https://get.docker.com/ | CHANNEL=stable bash
   

4. Run these commands:

   sudo ufw allow 80/tcp // if you have ufw installed/enabled
   sudo ufw allow 59000:59100/udp
   wget https://raw.githubusercontent.com/nurdism/neko/master/docker-compose.yaml
   sudo docker-compose up -d
   

5. Visit the IP address server in your browser and login, the default password is neko

💡 Protip: Run nano docker-compose.yaml to edit the settings, then press ctrl+x to exit and save the file.

Running:

Chromium container:

sudo docker run -p 80:8080 -p 59000-59100:59000-59100/udp -e NEKO_PASSWORD='secret' -e NEKO_ADMIN='secret' --cap-add SYS_ADMIN nurdism/neko:chromium

Note: --cap-add SYS_ADMIN is required for chromium to run properly

---

Firefox container:

sudo docker run -p 8080:8080 -p 59000-59100:59000-59100/udp -e NEKO_PASSWORD='secret' -e NEKO_ADMIN='secret' --shm-size=1gb nurdism/neko:firefox 

Note: --shm-size=1gb is required for firefox, tabs will crash otherwise

Docker Basic Configuration

SCREEN_WIDTH=1280       // Display width
SCREEN_HEIGHT=720       // Display height
SCREEN_DEPTH=24         // Display bit depth
DISPLAY=:99.0           // Display number

NEKO_PASSWORD=neko      // Password
NEKO_ADMIN=neko         // Admin Password
NEKO_BIND=0.0.0.0:8080  // Bind
NEKO_KEY=               // (SSL)Key, needed for clipboard sync
NEKO_CERT=              // (SSL)Cert, needed for clipboard sync

Development

Highly recommend you use a dev container for vscode, I've included the .devcontainer I've used to develop this app. To build n.eko docker container run:

cd .docker && ./build docker

the .docker folder also contains ./test <browser> bash script which will launch a desktop with a browser for testing out any changes with the server.

To run the client with hot loading (for development of new client features)

cd ./client && npm run serve

Non Goals

• Turning n.eko into a service that serves multiple rooms and browsers/desktops.
• Supporting multiple platforms
• Voice chat, use Discord
