This is a review of open source SIDU. If you haven't used SIDU, this is the right time to try! It is really one of the most easiest Web based SQL clients I've ever used. Simple down to what its name stands for: it executes SELECT, INSERT, DELETE, and UPDATE queries and displays results in a flexible table where you can hide certain columns or narrow down the search scope using built-in filtering feature. It's just great! You can find screenshots with explanations of key features.
