tinyjs: Build JavaScript Desktop Apps in <10MB — I built an app with this and was impressed. You get a txiki.js-powered backend with full system access (including FFI!), native webview rendering, and tiny macOS, Linux, and Windows builds. It even makes it easy to sign/notarize the final app.

There are lots of great options in this space though:

  • Electrobun offers richer multi-window and GPU features, at the cost of a larger TypeScript runtime – though it can instead use Zig, Rust, Go, or Odin for a tiny native main process.
  • Perry is a TypeScript to native AOT compiler whose primary UI model renders AppKit, Win32 and GTK4 widgets for a more conventionally native feel.
  • Electron and the experimental Deno Desktop are powerful, but their executables typically run several times larger.
  • Neutralinojs apps can be even smaller than tinyjs's, but you lose the general-purpose JavaScript privileged backend by design.

Do Frameworks Matter Anymore? — If you're using AI, you're either using a framework or your agent is building an ad-hoc one on the fly. A Remix team member argues that's a good reason to want frameworks, and better ones, too.
