The next-gen webOS and development environment with full Linux emulation.

What is AnuraOS?

An entirely local browser-based "OS" and development environment with complete graphical Linux emulation, visually based on ChromiumOS. See a demo here, fully in your browser.

[!WARNING]
Anura OS has only been extensively tested on Chromium and Safari. Although nearly everything should work on Firefox, you may run into problems with instability.

Anura uses the features of a PWA (Progressive Web App) to make its environment work fully offline, providing a virtual filesystem (synced with the Linux emulator), a code editor, and a modular and extensible app system. You can even edit Anura's code live while inside of it!

Anura shows as more of a proof-of-concept with what's possible on the modern web rather than an actual product. However, it proves useful in many actual cases and is a useful educational tool.

Development

[!IMPORTANT]
Anura will not build on Windows. Please use a Linux VM or WSL.

Easy Install for GitHub Codespaces

• Run bash codespace-basic-setup.sh

[!NOTE]

• If you are not in a codespace skip to the regular installation steps.
• This does NOT build RootFS.

Dependencies

• Recent versions of node.js and npm
• wget
• A recent version of java
• inotifytools
• rustup
• make
• gcc (or any other C compiler)

[!NOTE] You will have to install the required Rust toolchain by running rustup target add wasm32-unknown-unknown.

Building

• Clone the repository with git clone --recursive https://github.com/MercuryWorkshop/anuraOS
• Then, make all

[!TIP] You can use make all -B instead if you want to force a full build.

Building the Linux RootFS

• Make sure you have Docker installed and running.
• Run make rootfs
• Make sure to add yourself to the Docker group using usermod -a -G docker $USER
• (Special Use Case) In the event that you should need to override/manually add the initrd and kernel, remember to keep track of the file names of initrd and vmlinuz in build/images/(rootfs)-boot/. Then, copy them to the Anura root directory and rename them to initrd.img and bzimage respectively.(See the extended instructions here.)

Running Anura Locally

You can run Anura with the command

make server

Or, run authenticated with

cd server
npm start -- --auth

Anura should now be running at localhost:8000.

App Development

App development is highly encouraged! Good apps can even be added to the official workstore after review by an AnuraOS maintainer. Apps are stored in .app files which are read by AnuraOS to provide you, well, an app!

Documentation

Still being written. (See the current index of documentation here)

Security

See SECURITY.md for reporting instructions.
