I’m a web dev with a wife who is a researcher, and on the side I’ve built a few tools for her work. Web apps are great because cross-platform distribution and compatibility are non-issues. If you don’t need a database or server-side logic, a client-side only application is basically free to host given that it’s ultimately just a pile of static files. You can use localstorage for persistence, and because there’s no server logic you have a lot fewer security implications to worry about.

JavaScript gets a bad rap, but if you pair it with typescript and decent tooling it’s really not bad. HTML and CSS are an incredibly powerful engine for building UI, which is only getting better.
