Kloxo is a lightweight and powerful Web hosting panel that has been in development since 2002. It was formerly known as LxAdmin. It allows for adding customers, resellers, and wholesale resellers with few clicks. Clustering functions are also built in, so you can expand and add servers whenever you need. Migrating customers between servers is easy and automatic, making it the most extensible panel to date. The services installed by default are Apache, BIND, MySQL, Pure-ftpd, Qmail, and Bogofilter. You can also switch between Apache and Lighttpd, BIND and djbdns, Bogofilter and Spamassassin. All configuration files are converted automatically in the process.
STK/Unit is a pure SQL testing framework for MariaDB and MySQL. Users can create Base Tests (Stored Procedures) which are part of Test Cases (databases) and, optionally, Test Suites (other Stored Procedures). Output is stored in internal tables. You can convert it to a human-readable string, valid HTML, or query some convenient views which group results. It can be used to test any SQL structure (tables, views, triggers, stored routines), as well as server upgrades or configuration changes.
FreeTable is a cloud database service that allows programmers to upload and download individual data values using a SQL-like API. Language bindings exist for Python, PHP, and Ruby. In many respects FreeTable is a data wiki, with notions of revision history, curation, and data rollback/roll forward.
