Varnish is a high-performance HTTP accelerator. It acts as a caching reverse proxy and load balancer. You install it in front of any server that speaks HTTP and configure it to cache the contents through an extensive configuration language.

This is an HTTP to Gemini proxy designed to provide service for a single domain, i.e. to make your Gemini site available over HTTP. It can proxy to any domain in order to facilitate linking to the rest of Geminispace, but it defaults to a specific domain.

Hitch is a performant TLS proxy based on libev. It terminates SSL/TLS connections and forwards the unencrypted traffic to a backend such as a web server. It is designed to handle many thousand connections on multicore machines.

LibSass is a SASS compiler library designed for portability and efficiency. To actually compile SASS stylesheets, you'll need to use another program that uses this library, sassc for example.

This package contains support scripts called by libquvi to parse media stream properties.

PSGI is a specification to decouple web server environments from web application framework code. Test::WWW::Mechanize is a subclass of WWW::Mechanize that incorporates features for web application testing.

Woof (Web Offer One File) is a small simple web server that can easily be invoked on a single file. Your partner can access the file with tools they trust (e.g. wget).

This module attempts to make using HTML templates simple and natural. It extends standard HTML with a few new HTML-esque tags: <TMPL_VAR>, <TMPL_LOOP>, <TMPL_INCLUDE>, <TMPL_IF>, <TMPL_ELSE> and <TMPL_UNLESS>. The file written with HTML and these new tags is called a template. Using this module you fill in the values for the variables, loops and branches declared in the template. This allows you to separate design from the data.

SSL support for Net::SMTP.

A "public suffix" is a domain name under which Internet users can directly register own names.

Browsers and other web clients can use it to avoid privacy-leaking "supercookies", avoid privacy-leaking "super domain" certificates, domain highlighting parts of the domain in a user interface, and sorting domain lists by site.

Libpsl has built-in PSL data for fast access, allowing to load PSL data from files, checks if a given domain is a public suffix, provides immediate cookie domain verification, finds the longest public part of a given domain, finds the shortest private part of a given domain, works with international domains (UTF-8 and IDNA2008 Punycode), is thread-safe, and handles IDNA2008 UTS#46.

Binaryen is a compiler and toolchain infrastructure library for WebAssembly, written in C++. It aims to make compiling to WebAssembly easy, fast, and effective.

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.

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.

Qhttp is a light-weight and asynchronous HTTP library (both server & client) in Qt5 and C++14.

This module is a Catalyst view class for the Template Toolkit.

uWSGI presents a complete stack for networked/clustered web applications, implementing message/object passing, caching, RPC and process management. It uses the uwsgi protocol for all the networking/interprocess communications.

The authentication plugin provides generic user support for Catalyst apps. It is the basis for both authentication (checking the user is who they claim to be), and authorization (allowing the user to do what the system authorises them to do).

This module allows your to run your Plack::Test tests against an external server instead of just against a local application through either mocked HTTP or a locally spawned server.
