One niche platform is Sandstorm. Because of the way it is architected, a single “grain” is started up for a single document. So fast startup and small footprint is very useful, even if it is still a web platform. As much as I like Elixir, it wouldn’t do as well running within Sandstorm as something written in Rust.
