quark
suckless.org
The goal of this project is to do one thing and do it well, namely serving static web directories and doing that right. Most other solutions either are too complex (CGI support, dependencies on external libraries, etc.) or lack features you expect (TLS, virtual hosts, partial content, not modified since, etc.). quark tries to find a midway and just restrict itself to being static while still offering functions you only find in more bloated solutions and being as secure as possible (chroot, privilege dropping, strict parsers, no malloc at runtime, pledge, unveil, etc.). We believe that most of the web does not need to be dynamic and increasing complexity on server-side applications is one of the main reasons for the web obesity crisis. The common approach nowadays is to do everything on the server, including parsing requests, modifying files and databases, generating HTML and all that using unfit languages like PHP or JavaScript, which is a security and efficiency nightmare. -

Pacman
Pacman
Pacman is a utility which manages software packages in Linux. It uses simple compressed files as a package format, and maintains a text-based package database (more of a hierarchy), just in case some hand tweaking is necessary. Pacman does not strive to "do everything." It will add, remove and upgrade packages in the system, and it will allow you to query the package database for installed packages, files and owners. It also attempts to handle dependencies automatically and can download packages from a remote server. Version 2.0 of Pacman introduced the ability to sync packages (the - sync option) with a master server through the use of package databases. Prior to this, packages would have to be installed manually using the --add and - upgrade operations.Starting Price: Free -
