We’re excited to tell you about OAuth.tools - An OAuth laboratory where you can easily connect to any OAuth server and try the full set of flows. The clean UI lets you see the flows clearly, in what order things happen, what tokens are returned and if signatures are valid and so on.
It’s a great way to learn and explore the inner workings of OpenID Connect and OAuth. Also, it’s free to use so don't hesitate to share the link with friends and colleagues.
You can take a look here oauth.tools
We hope you'll find it useful!
