Founder of SecretHub here, big kudos on the GUI Doppler made, looks amazing.

Aside from a feature-by-feature comparison, I feel that both SecretHub and Doppler do a great job of:

1) making secrets management simple enough so any engineer can use it with limited overhead.

2) making secrets management work throughout your entire stack – from development to production – and not just inside one ecosystem.

Finally, we see a trade-off between usability and security being made. At SecretHub, we feel end-to-end encryption is a must for any managed service handling passwords, API keys and other secrets.
