MyWebSQL is the fast web-based MySQL administration app ultimate desktop replacement for managing your MySQL databases over the web. With interface that works just like your favourite desktop applications, you don’t need to keep switching over webpages to get simple things done. Just login to your database and manage your database as if your are working on your desktop!
MyWebSQL is an exciting open source alternative to both as it is a web-based MySQL (and SQLite) manager with a desktop-like functionality.
It is built with PHP and, with the help of a completely Ajaxed interface, tasks can be accomplished pretty quickly.

Creating, editing and deleting tables or records are easily done in a grid mode which also makes working with multiple items at the same time possible. Also, shortcuts for any actions exist inside context menus to make browsing faster.
There are other must-have features like import-export, SQL editor (with syntax highlighting), repair tables, search, process manager, etc.
Rich set of features
- Application and right click menus
- Multiple syntax highlighted sql editors
- Quick Inplace multi-record editing
- Zero configuration installation
- Multiple server login supported
- Excellent support for major browsers
- WYSIWYG Table creator/editor
- Batch Import/Export modules
- UI Themes supported
MyWebSQL is a multilanguage app with lots of ready-to-use languages and has a themable interface.
Imho, what is missing the most is the ability to manage multiple server connections with a single login and scheduled tasks (which I hope would exist in the future versions).
That’s right. MyWebSQL is completely open source software and available free for download. You can add/edit/change whatever you like. It even supports themes so you can create your own to suit your needs!
