Libnsgif is a decoding library for the GIF image file format, written in C. It is developed as part of the NetSurf project.

Catalyst::View::JSON is a Catalyst View handler that returns stash data in JSON format.

The Catalyst-Devel distribution includes a variety of modules useful for the development of Catalyst applications, but not required to run them. Catalyst-Devel includes the Catalyst::Helper system, which autogenerates scripts and tests; Module::Install::Catalyst, a Module::Install extension for Catalyst; and requirements for a variety of development-related modules.

Fcgiwrap is a simple server for running CGI applications over FastCGI. It hopes to provide clean CGI support to Nginx (and other web servers that may need it).

Iter Vitae is a command-line utility that allows you to generate a Resume / CV, by reading a S-expression version of your CV details (in Scheme code).

With a MVC approach, it lets you separate the data from the presentation (how the document looks).

This tool creates a web-site version of your CV (using SXML and Olive CSS), and is designed for long-term use, so you can update and evolve your CV over the years. The program supports multilingual content and is fully extensible.

The Guix Data Service stores data about GNU Guix, and provides this through a web interface. It supports listening to the guix-commits mailing list to find out about new revisions, then loads the data from these in to a PostgreSQL database.

CGI::Simple provides a relatively lightweight drop in replacement for CGI.pm. It shares an identical OO interface to CGI.pm for parameter parsing, file upload, cookie handling and header generation.

Hubbub is an HTML5 compliant parsing library, written in C, which can parse both valid and invalid web content. It is developed as part of the NetSurf project.

This module will attempt to load find and load configuration files of various types. Currently it supports YAML, JSON, XML, INI and Perl formats.

The Apache HTTP Server Project is a collaborative software development effort aimed at creating a robust, commercial-grade, featureful, and freely-available source code implementation of an HTTP (Web) server. The project is jointly managed by a group of volunteers located around the world, using the Internet and the Web to communicate, plan, and develop the server and its related documentation.

Starman is a PSGI perl web server that has unique features such as high performance, preforking, signal support, superdaemon awareness, and UNIX socket support.

This module is a Moose::Role which allows you more flexibility in your application's deployment configurations when deployed behind a proxy. Using this module, the request base ($c->req->base) is replaced with the contents of the X-Request-Base header.

nghttp2 implements the Hypertext Transfer Protocol, version 2 (HTTP/2).

A reusable C library provides the HTTP/2 framing layer, with several tools built on top of it:

• nghttp, a command-line HTTP/2 client. It exposes many advanced and low-level aspects of the protocol and is useful for debugging.

• nghttpd, a fast, multi-threaded HTTP/2 static web server that serves files from a local directory.

• nghttpx, a fast, multi-threaded HTTP/2 reverse proxy that can be deployed in front of existing web servers that don't support HTTP/2. Both nghttpd and nghttpx can fall back to HTTP/1.1 for backwards compatibility with clients that don't speak HTTP/2.

• h2load for benchmarking (only!) your own HTTP/2 servers.

• HTTP/2 uses a header compression method called HPACK. nghttp2 provides a HPACK encoder and decoder as part of its public API.

• deflatehd converts JSON data or HTTP/1-style header fields to compressed JSON header blocks.

• inflatehd converts such compressed headers back to JSON pairs.

Yder is a logging library written in C. It can log messages to the console, a file, syslog, journald, or a callback function.

CGI.pm is a stable, complete and mature solution for processing and preparing HTTP requests and responses. Major features include processing form submissions, file uploads, reading and writing cookies, query string generation and manipulation, and processing and preparing HTTP headers.

This is a very simple HTTP/1.1 client, designed for doing simple requests without the overhead of a large framework like LWP::UserAgent. It supports proxies and redirection. It also correctly resumes after EINTR.

The HTTP::Negotiate module provides a complete implementation of the HTTP content negotiation algorithm specified in draft-ietf-http-v11-spec-00.ps chapter 12. Content negotiation allows for the selection of a preferred content representation based upon attributes of the negotiable variants and the value of the various Accept* header fields in the request.

LWPx::ParanoidAgent is a class subclassing LWP::UserAgent but paranoid against attackers. Its purpose is to vet requests for a remote resource on behalf of a possibly malicious user. The class can do the same as LWP::UserAgent, except that proxy support has been removed. Support for URI schemes is limited to http and https.

HTML::Tidy is an HTML checker in a handy dandy object. It's meant as a replacement for HTML::Lint, which is written in Perl but is not nearly as capable as HTML::Tidy.

The Catalyst::Authentication::Store::DBIx::Class class provides access to authentication information stored in a database via DBIx::Class.

Gumbo is an implementation of the HTML5 parsing algorithm implemented as a pure C99 library.

This NGINX module provides access to virtual host status information, similar to live activity monitoring provided with NGINX plus.

CivetWeb is a web server with optional CGI and SSL support. It can be embedded into C/C++ applications or used as a standalone web server.

LibCSS is a CSS (Cascading Style Sheet) parser and selection engine, written in C. It is developed as part of the NetSurf project.
