Doppler is a DevOps tool, not an onboarding tool. More importantly, Doppler is not zero-knowledge; their servers must decrypt your secrets to inject them into hosting environments. This introduces a vector of vulnerability that agencies shouldn't risk for client credentials. Keze guarantees zero-knowledge isolation. The decryption key lives purely in the URL hash fragment, meaning not even the Keze database could read the client's payload if it wanted to.
