Wisp is a Lisp system for [[https://webassembly.org][WebAssembly]] and native execution.

It aims to offer an unusually pleasant developer experience both while hacking and in production, though it's still /very immature/ and far from ready for any serious use.

You can try the live browser-based IDE at [[https://wisp.town][Wisp.Town]].

Feel free to join the [[https://discord.gg/BeKtM3x687][Wisp Discord chat]] if you're interested in following the development work, hacking on the system, or chatting about Lisp, WebAssembly, and Zig.

Wisp has:

• a browser-based IDE for live hacking and interactive debugging;

• saving and loading of full system state images, including debugger state, also in browser local storage;

• thoughtful integration with the browser environment, Node, Deno, and Unix in general;

• first-class delimited continuations for advanced control flow;

• interactive restartable conditions in the style of Common Lisp;

• first-class stepwise execution for custom debuggers, schedulers, etc;

• sandboxed execution with fine-grained capabilities via WebAssembly;

• an implementation written in [[https://ziglang.org][Zig]];

• and more!
