QuickMoker โ€’ Online API Mocking Tool. Mock API or create fake web services (rest, soap etc) based on the HTTP(S) protocol. Alternatively simulate API, stub API, fake API or create API for tests. Perform an instant live debugging of requests to endpoints with an extensive information about request headers, body etc. More than 100 random or faker shortcodes for response templating. Forward the requests to your localhost with the help of the Local Forwarder feature. Proxy requests to any external URL, restrict fake API endpoint by IP address or authorization header. Use regular expression for your URL paths, multiple HTTP methods per fake API endpoint, endpoint prioritization etc.

QuickMocker has a free subscription plan which is enough for most of development and testing needs and it does not require any credit cards.
