  • Debuk

    Debuk is a wrapper to any function or class. Users can debug and test their JavaScript applications' code performance with a minimum setup. It has many utility functions that allow wrapping any function or class, checking different runtime behaviors.

  • EzNav

    EzNav is a Chrome extension that allows users to quickly search all the open tabs and the history for specific content. It is handy to navigate back to a page where users were on when they have multiple windows with multiple tabs. It also searches the URLs in the history.
