Krona is a flexible tool for exploring the relative proportions of hierarchical data, such as metagenomic classifications, using a radial, space-filling display. It is implemented using HTML5 and JavaScript, allowing charts to be explored locally or served over the Internet, requiring only a current version of any major web browser.

Catalyst::Plugin::Authorization::Roles provides role-based authorization for Catalyst based on Catalyst::Plugin::Authentication.

Iocaine is an HTTP server that generates a stable endless maze of Markov-babble-filled web pages. Placed behind a heavily rate-limited reverse proxy, it becomes a ``tar pit'' for trapping aggressive web scrapers commonly used to train large language models, and poisoning the collected data.

httptunnel creates a bidirectional virtual data connection tunnelled through HTTP (HyperText Transfer Protocol) requests. This can be useful for users behind restrictive firewalls. As long as Web traffic is allowed, even through a HTTP-only proxy, httptunnel can be combined with other tools like SSH (Secure Shell) to reach the outside world.

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

Py-ubjson is a Python module providing an Universal Binary JSON encoder/decoder based on the draft-12 specification for UBJSON.

This module provides methods to compile a log format string to perl-code, for faster generation of access_log lines.

IO::HTML provides an easy way to open a file containing HTML while automatically determining its encoding. It uses the HTML5 encoding sniffing algorithm specified in section 8.2.2.1 of the draft standard.

Hiawatha has been written with security in mind. Features include the ability to stop SQL injections, XSS and CSRF attacks and exploit attempts.

Kiwix Desktop allows you to enjoy a lot of different content offline (such as Wikipedia), without any access to Internet.

The Net::HTTP class is a low-level HTTP client. An instance of the Net::HTTP class represents a connection to an HTTP server. The HTTP protocol is described in RFC 2616. The Net::HTTP class supports HTTP/1.0 and HTTP/1.1.

htmlcxx is a simple non-validating CSS1 and HTML parser for C++. Although there are several other HTML parsers available, htmlcxx has some characteristics that make it unique:

• STL like navigation of DOM tree, using excelent's tree.hh library from Kasper Peeters

• It is possible to reproduce exactly, character by character, the original document from the parse tree

• Bundled CSS parser

• Optional parsing of attributes

• C++ code that looks like C++ (not so true anymore)

• Offsets of tags/elements in the original document are stored in the nodes of the DOM tree

This Catalyst action implements a sensible default end action, which will forward to the first available view.

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.

Lighttpd is a secure, fast, compliant, and very flexible web-server that has been optimized for high-performance environments. It has a very low memory footprint compared to other webservers. Its features include FastCGI, CGI, authentication, output compression, URL rewriting and many more.

HTML::Scrubber Perl extension for scrubbing/sanitizing HTML.

This is an HTTP request parser. It takes chunks of text as received and returns a hint as to what is required, or returns the HTTP::Request when a complete request has been read. HTTP/1.1 chunking is supported.

Leafnode is a caching Usenet news proxy that enables online newsreaders to read news off-line and aggregates news from various NNTP servers into one.

WASM3 is a fast WebAssembly interpreter.

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 the JMX management.

RapidJSON is a fast JSON parser/generator for C++ with both SAX/DOM style API.

This Catalyst plugin enables you to create "access logs" from within a Catalyst application instead of requiring a webserver to do it for you. It will work even with Catalyst debug logging turned off.

Wslay is an event-based C library for the WebSocket protocol version 13, described in RFC 6455. Besides a high-level API it provides callbacks for sending and receiving frames directly. Wslay only supports the data transfer part of WebSocket protocol and does not perform the opening handshake in HTTP.

Universal feed parser which handles RSS 0.9x, RSS 1.0, RSS 2.0, CDF, Atom 0.3, and Atom 1.0 feeds.
