Main thing was support for ligatures which Alacritty does not support: https://github.com/alacritty/alacritty/issues/50

As someone who doesn't use tmux, two features pushed me to this over Alacritty: native scrollback with a scrollbar, and native tabs.

Tabs, splits, programmability, best-in-class graphics support, an ssh multiplexor, session management, Lua scripting.

Alacritty and Wezterm have very different--if not opposite--philosophies. Choose Alacritty if you want something simple, fast, focused, done right. Choose WezTerm for flexibility and being a cross-platform environment by itself.

Ligatures is one. I also find the copy mode and the hyperlinks feature [1] handy.

Lower OpenGL / GLES version number requirements, so wezterm can run on Arm64 hardware with no hassle.
