atmo

Atmo provides a visual interface for quickly defining mock HTTP endpoints without server setup, aligning with its philosophy of making mocking ridiculously easy.

It supports JSON, XML, and plain text responses, allowing developers to simulate various API scenarios for demos and testing.

Users can write custom JS scripts to generate dynamic responses, adding logic without full backend development, as highlighted in the features.

With one-click deployment to Zeit Now, mock services can be easily shared and presented, simplifying the process for demos.
