Cierge vs Copper: What are the differences?
Developers describe Cierge as "Easy magic-link authentication". Cierge is an open source authentication server (OIDC) that handles user signup, login, profiles, managerment, and more. Instead of storing passwords, Cirege uses magic links/codes and external logins to authenticate your users. On the other hand, Copper is detailed as "Password-free signups. No social network required". People sign up with their number. You get verified info. Copper is a service for developers who want a seamless, always-improving signup and signin flow in their websites and iOS apps. We remove friction so more people become and remain users, while makers ship faster and maintain less code.
Cierge and Copper can be categorized as "User Management and Authentication" tools.
