Thanks! It's the first time I get to see Clavier so I'm not very prepared, but some differences could be:
1. Espanso is cross-platform, so you create your config once and then run it on all your machines 2. Clavier comes with a GUI, but espanso does not (yet) 3. Espanso is highly flexible thanks to scripts [1] and forms [2]
