This is a simple HTTP server that logs out various info about any HTTP request made to it. Use for debugging or whatever.
You can obviously deploy to whatever you'd like, but Heroku is simple and free for this. Presuming you have a Heroku account and are logged in via the CLI tool:
heroku create
heroku push remote main
Then, once it's deployed, send any HTTP request to your Heroku endpoint, and finally view the logs:
heroku logs
