There is kore. See https://kore.io and https://github.com/jorisvink/kore

Has quite alot of neat features for C web development imho, then again I wrote it so of course I like it.

That's very interesting work. I did a similar thing for Kore for its background task implementation so that page handlers could talk to its tasks it fired off and read its responses accordingly.

See example on https://github.com/jorisvink/kore/tree/master/examples/tasks

nice!, its good to see many people working on that area. We got a lot of support from the author of LWan (http://lwan.ws) project during the development process.

And then there is also Kore: https://kore.io
