Adminer

Adminer is a tool for managing content in databases. It natively supports MySQL, MariaDB, PostgreSQL, SQLite, MS SQL, Oracle, Elasticsearch and MongoDB. Adminer is distributed under Apache license in a form of a single PHP file. Its author Jakub Vrána started to develop this tool in July 2007 as a light-weight alternative to phpMyAdmin. Adminer got some attention in 2008 when it made it to the CCA finals at SourceForge. Also, first webhosting providers started to include Adminer as MySQL managing tool into their portfolio of services. In 2012 Adminer got coverage on Linux.com for the second time. The project's priorities, according to its author, are : safety, user-friendliness, performance, functionality, and size.
