I've just found out MockServer and it looks awesome 🤩 so I wanted to check it out repeating the steps of my previous demo WireMock Testing which (as you can expect) uses WireMock, another fantastic tool to mock APIs. - Source: dev.to / about 2 years ago

Are there any other places, like these, that can be of use? :). Source: about 1 year ago

You could try https://leakcheck.net/ or https://www.dehashed.com/ (personally best for me) but they are paid unfortunately. Source: over 2 years ago

I think https://leakcheck.net/ might be the one you're looking for. For personal emails I use hacknotice.com. Source: about 3 years ago
