Observer Web

Observer Web is an easy-to-use tool that integrates into your application to provide observability. It relies on the OTP distribution to offer tracing using the Erlang debugger, as well as Process/Port status and details.

Powered by Phoenix LiveView, it is distributed, lightweight, and fully real-time. This library is part of the DeployEx project.
