ashttpd was originally a testbed for a kernel async-sendfile patch. Today, it's just another Web server for serving static content rapidly.

phpLiteAdmin is a Web-based database admin tool with support for SQLite 2 and 3. It consists of a single 60KB source file that can simply be dropped into a directory on your server and then visited in a browser.

once:radix is an integrated development environment (IDE) that operates entirely within a Web browser. once:radix supports two methods of connecting to the server. Most interest is focused on its Rich Internet Application (RIA) environment. This comes with a suite of five RIAs that perform specific roles: logging on or off, context-sensitive help, database administration, IDE, and client. In addition, the once:secureserver (oSS) can respond to commands from session-managed external Web servers.
