Ulfius is a HTTP Framework library for REST Applications written in C. It is based on GNU libmicrohttpd for the backend web server, Jansson for the JSON manipulation library, and libcurl for the http/smtp client API. It can be used to facilitate creation of web applications in C programs with a small memory footprint, as in embedded systems applications. It can create webservices in HTTP or HTTPS mode, stream data, or implement server websockets.

IO::Socket::SSL makes using SSL/TLS much easier by wrapping the necessary functionality into the familiar IO::Socket interface and providing secure defaults whenever possible. This way existing applications can be made SSL-aware without much effort, at least if you do blocking I/O and don't use select or poll.

HTTP::Lite is a stand-alone lightweight HTTP/1.1 implementation for perl. It is intended for use in situations where it is desirable to install the minimal number of modules to achieve HTTP support. HTTP::Lite is ideal for CGI (or mod_perl) programs or for bundling for redistribution with larger packages where only HTTP GET and POST functionality are necessary. HTTP::Lite is compliant with the Host header, necessary for name based virtual hosting, and supports proxies. Additionally, HTTP::Lite supports a callback to allow processing of request data as it arrives.

jq is like sed for JSON data – you can use it to slice and filter and map and transform structured data with the same ease that sed, awk, grep and friends let you play with text. It is written in portable C. jq can mangle the data format that you have into the one that you want with very little effort, and the program to do so is often shorter and simpler than you'd expect.
