v0.2.0 alpha

a modern and extensible pixel editor implemented in rust

Download for GNU/Linux

rx is an extensible, modern and minimalist pixel editor and animator implemented in rust[0]. It's designed to have as little UI as possible, and instead takes inspiration from vi's[1] modal nature and command mode.

Compared to other pixel editors, rx aims to be smaller yet more configurable and extendable. rx takes a different approach when it comes to animation as well, which is done with *strips*.

On Linux, Vulkan support is required. The drivers can be installed for example with apt install mesa-vulkan-drivers on debian-based systems.


On macOS, Metal support is required. This usually requires installing Xcode and the Xcode Command Line Tools.


On Windows, Vulkan support is required.


Disclaimer: this is alpha software, use at your own risk!

On Linux, the simplest way to get rx is to download the AppImage from here:


Then make it executable with eg. chmod +x, rename it to rx and move it somewhere in your PATH.

For macOS and Windows, see the following section.


You'll need cargo and rust to build rx from source. For more detailed instructions, see the README.

$ cargo install --git https://github.com/cloudhead/rx --tag v0.2.0 --locked

The default installed palette is sweetie16.palette. Other palettes are also available here, and you can create your own.


After installing, simply run rx from a shell or application launcher. You can then use the :help command to show the current set of key mappings and commands.

Common commands:

:help                    Display help
:e <path..>              Edit path(s)
:w                       Write/save view
:q                       Quit view
:slice <n>               Slice view into <n> frames
:source <path>           Source an rx script (eg. a palette)
:f/resize <w> <h>        Resize frames


Configuring rx involves editing the init.rx script, which is found in a platform-dependent location. On Linux, this is in the XDG config directory, eg. ~/.config/rx/init.rx, while on macOS this is in the ~/Library/Preferences folder. written.

To get the exact location of the config directory, enter :echo config/dir from inside rx.


The source code is available at github.com/cloudhead/rx. rx is free software.


If you find this project useful and want to support its continued maintenance, consider sending ₿ (Bitcoin) to the following address with a memo indicating your name, to be added to the contributors list:



If something ain't working like it's supposed to, there are various things you can do to debug the problem:

  1. Run rx with verbose logging, by using the -v command-line flag. This will log errors from the underlying libraries that are usually suppressed. You can increase the verbosity further by using -vv.
  2. Try the winit backend, by building rx with eg. --features winit.
Otherwise, see the following BUGS section.


If you encounter a bug, please open an issue on the tracker or send an email to rx@cloudhead.io.
