Render quality of the fractal

The quality of the fractal depends on how many pixels you have in your terminal, if you want to display more pixels, on most terminals you can do so with ctrl+- or by scrolling the mouse wheel.

Note: The more pixels you display in your terminal, the slower the rendering will be

Recommended Terminals

You can run fractals-cli in most Unix and Windows terminals. However, for the best visual experience and performance, we recommend using one of the tested terminals below:

• ghostty (Fastest native macOS/Linux GPU-accelerated terminal)
• alacritty (Fastest in rendering and more pixels)
• kitty
• gnome-terminal
• konsole
• terminator
• yakuake
• xfce4-terminal
• windows terminals
