This is an extremely basic website meant to act as an API simulator. You run it on your machine at localhost:8080 (or whatever you prefer), point your app/framework at it and check to see exactly what parameters are received.

I use this when preparing API testing tools to make sure that the tool is building the request in the way that I expect. You can also use it to test HTML forms or any other link builder.

I maintain a Docker Hub image of this so usage is a simple as:

docker run -p 127.0.0.1:8080:80 --rm --name api-test-backend docker.io/patricktcb/api-sim:latest

The actual webpage is a modified version of the Clean Blog bootstrap theme.
