RestfulDB is a Web frontend for SQL databases. It provides both a Web GUI and a RESTful API for interaction with any MySQL/MariaDB or SQLite database. RestfulDB is developed with off-the-shelf usage in mind, but nevertheless it provides the means to override the default interpretations of underlying database's schema and data.
Convos is a multiuser chat application that runs in your web browser. The supported chat protocol is currently IRC, but Convos can be extended to support other protocols as well. The backend is powered by Mojolicious, while the frontend is held together by the progressive JavaScript framework Svelte. One-script installation support, but that means piping curl right into a shell - what could possibly go wrong?
A script which digs up and displays lots of system configuration information, such as the specifics of the CPUs, storage devices (with identifying information) and space free, version numbers of common utilities, known hardware vulnerabilities, memory, and more. Even if you don't run it as root, you'll still get really useful information out of it.
Written in Perl but don't let that stop you.
