MonoLisa has a playground where you can paste code snippets and try the font - that might be a good approach for other fonts aimed at developers. https://www.monolisa.dev/playground
MonoLisa also has a trial version. [1] They have a great site, I love the font, and the availability of a free trial was the icing on the cake. Great experience all around.
