SCA Toolbar is a free Chrome add-on developed by raxel. It displays a convenient toolbar at the bottom of the screen, allowing developers to quickly switch between local and non-local modes in the SSP's (Server-Side Platforms). With just a click, this extension eliminates the need for manual searching and hacking to find the local URL on SCA.

One of the standout features of SCA Toolbar is its ability to provide small notifications when it detects a local extension server running. This feature ensures that developers are always aware of the status of their local server, making it easier to track and manage their development environment.

Overall, SCA Toolbar is a valuable tool for developers working with Server-Side Platforms. Its seamless switching between local and non-local modes, along with the notifications for local extension servers, enhance productivity and streamline the development process.
