I wrote one: https://github.com/tom-seddon/yhs https://github.com/tom-seddon/yhs (README includes a bunch of links to others at the bottom) I wrote it for an iOS game, the idea being that configuration of the game would be done in real time by connecting to your iThing via a web browser and tweaking it using a bunch of HTML widgets or whatever. But its intended users ended up preferring to do their tweaking using some on-screen Cocoa Touch stuff that I'd also put in, so the HTML idea never ended up being taken further. My library has a few good points, I think: no dependencies, no threading, easy integration, simple API, builds as C89/C99/C++, doesn't hate Windows. (I've often wished other libraries did all of those.) But I don't currently have any plans to work on it further, and you can probably find other options that have been more thoroughly battle-tested, were more carefully planned, and are actively maintained. (These days I'm more comfortable with Javascript, and I've come to the conclusion that a better approach would be to implement a bare bones WebSocket server that does little more than let the iWhatever send data to the browser and vice versa. No need for the iDevice to serve any HTML or cooked data or anything like that; just send raw data and interpret it in your JS code, which of course would be stored locally on your PC, along with associated HTML/CSS/etc. Quicker turnaround during development, and easier to push updates to its users, who would probably just need to get latest and hit refresh in the browser as they'd be running it straight from their working copy.)
