janet looks really really good ! I like the use of channels for m.t

Any good HTTP/JSON/Crawler examples or libraries ?

libcurl wrapper - https://github.com/sepisoad/jurl

json encoder/decoder - https://github.com/janet-lang/json

Not aware of any HTML parsers/traverses (if that's what you mean with "Crawler") but interfacing with C libraries is easy so grab any C library you'd like for that task.
