      James is a HTTP Proxy and Monitor that enables developers to view and intercept requests made from the browser. It is an open-source alternative to the popular developer tool Charles.

      Discontinued

      Not sure if 'discontinued' is quite right, but James has now officially moved in 'maintenance mode', with little or no ongoing development or support. See the readme: https://github.com/james-proxy/james#this-project-is-in-maintenance-mode.

      It would be helpful to highlight that here imo.
