Popcorn
Running Elixir in the browser
...The project is still early and may introduce breaking changes, so it is best suited for experimentation, prototypes, and research rather than stable production use. Popcorn connects Elixir’s programming model with browser-based execution, opening the door for local interactive experiences and future LiveView-style ideas. It is useful for developers interested in WebAssembly, local-first interfaces, and alternative ways to build browser applications. Its main value is exploring what Elixir development can look like when part of the application logic runs directly on the client.
