Objects of the HTML::Parser class will recognize markup and separate it from plain text (alias data content) in HTML documents. As different kinds of markup and text are recognized, the corresponding event handlers are invoked.

NetSurf is a lightweight web browser that has its own layout and rendering engine entirely written from scratch. It is small and capable of handling many of the web standards in use today.

WWW::Mechanize is a Perl module for stateful programmatic web browsing, used for automating interaction with websites.

libjuice opens bidirectionnal User Datagram Protocol (UDP) streams with Network Address Translator (NAT) traversal. It's a simplified implementation of the Interactive Connectivity Establishment (ICE) protocol, client-side and server-side, written in C without dependencies for POSIX platforms.

Tibanna runs portable pipelines (in CWL/WDL and Snakemake) on the AWS Cloud.

JSON-C implements a reference counting object model that allows you to easily construct JSON objects in C, output them as JSON-formatted strings and parse JSON-formatted strings back into the C representation of JSON objects. It aims to conform to RFC 7159.

This package provides awslogs, a simple command line tool to download and read AWS CloudWatch logs. The same functionality is available from aws logs tail.

This NGINX module provides a scripting support with Lua programming language.

Test::TCP is test utilities for TCP/IP programs.

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

Cat avatar generator is a generator of cat pictures optimised to generate random avatars, or defined avatar from a "seed". This is a derivation by David Revoy from the original MonsterID by Andreas Gohr.

Ikiwiki is a wiki compiler, capable of generating a static set of web pages, but also incorporating dynamic features like a web based editor and commenting.

Vger is a Gemini protocol server that supports chroots, virtualhosts, CGI, default language choice, redirections and MIME-type detection. It delegates TLS support to an external daemon, for example stunnel on inetd.

CGI::FormBuilder provides an easy way to generate and process CGI form-based applications.

WABT (pronounced: wabbit) is a suite of tools for WebAssembly, including:

1. wat2wasm translates from WebAssembly text format to the WebAssembly binary format

2. wasm2wat is the inverse; it translates from the binary format back to the text format (also known as a .wat)

3. wasm-objdump prints information about a wasm binary, similarly to objdump.

4. wasm-interp decodes ands run a WebAssembly binary file using a stack-based interpreter

5. wat-desugar parses .wat text form as supported by the spec interpreter (s-expressions, flat syntax, or mixed) and prints the canonical flat format

6. wasm2c converts a WebAssembly binary file to a C source and header file.

These tools are intended for use in (or for development of) toolchains or other systems that want to manipulate WebAssembly files.

Jsoup is a Java library for working with real-world HTML. It provides a very convenient API for extracting and manipulating data, using the best of DOM, CSS, and jQuery-like methods.

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.

The Jetty Web Server provides an HTTP server and Servlet container capable of serving static and dynamic content either from a standalone or embedded instantiation. This package provides utility classes.

This NGINX module allows adding, setting, or clearing any output or input header specified.

This is an enhanced version of the standard headers module because it provides more utilities like resetting or clearing "builtin headers" like Content-Type, Content-Length, and Server.

It also allows you to specify an optional HTTP status code criteria using the -s option and an optional content type criteria using the -t option while modifying the output headers with the more_set_headers and more_clear_headers directives.

This package contains helper classes for testing the Jetty Web Server.

In order for Catalyst::Plugin::Session to work, the session ID needs to be stored on the client, and the session data needs to be stored on the server. This plugin stores the session ID on the client using the cookie mechanism.

This plugin links the two pieces required for session management in web applications together: the state, and the store.

uriparser is a strictly RFC 3986 compliant URI parsing and handling library written in C89 ("ANSI C"). uriparser is fast and supports Unicode.
