snowglobe

Package a Docker image into a website that runs it in the browser. snowglobe boots your image on real Linux inside armless, a 64-bit ARM machine compiled to WebAssembly, snapshots it once your app is ready, and writes a folder of static files. Visitors get your program running in their tab in about a second, with no server behind it. The same site also runs headlessly, as one executable, and as a sandbox an agent drives.

▶ Try the demos: Supabase (its native stack and a small app on it), Elixir IEx, PostgreSQL, Elixir + Postgres, Python + Rich, TypeScript + Zod, Go + Bubble Tea, Rust + clap, Java + Gson, and curl + jq (plain Alpine tools, online through your browser), each a small project in examples/ running in the browser.
