Yes.
Shameless plug: I'm giving a talk at Elixir Conf next week on using Gleam with Phoenix LiveView. One of my demos is an emulator I wrote in Gleam that I render and control with LiveView, in the browser. Plum Mail [0] is also a Y Combinator funded startup implemented in Gleam.
The community + ecosystem is small and in its early stages, but there's a lot of exciting stuff happening.
