Clutch vs Atlas: What are the differences?

Clutch: The Open-Source Platform for Infrastructure Tooling (by Lyft). It provides everything you need to improve your developers' experience and operational capabilities. It comes with several out-of-the-box features for managing cloud-native infrastructure, but is easily configured or extended to interact with whatever you run, wherever you run it; Atlas: Develop, deploy, and maintain your application anywhere. Use one console and one workflow from development to production. Atlas is one foundation to manage and provide visibility to your servers, containers, VMs, configuration management, service discovery, and additional operations services.

Clutch and Atlas can be categorized as "Infrastructure Build" tools.
