Why Migrate Away from Doppler & AWS Secrets Manager?

Developer secrets, API tokens, and credentials are the keys to your entire infrastructure kingdom. Relying on closed-source third-party SaaS introduces supply-chain breach risks and high monthly seat licenses. Self-hosting Infisical or Phase provides automated end-to-end encryption, multi-environment synchronization (local, staging, prod), automatic secret rotation, and CLI injectors at zero per-developer fee.
