Facebook Sonar's Features
  • Mobile development - Sonar aims to be your number one companion for mobile app development on iOS and Android. Therefore, we provide a bunch of useful tools including a log viewer, interactive layout inspector, and network inspector.
  • Extending Sonar - Sonar is built as a platform. In addition to using the tools already included, you can create your own plugins to visualize and debug data from your mobile apps. Sonar takes care of sending data back and forth, calling functions, and listening for events on the mobile app.
