Frequently Asked Questions
Should I choose Infisical or HashiCorp Vault (or OpenBao) for managing AI API keys and application secrets in 2026?
Choose Infisical (`Infisical/infisical`, 29.8k stars) when you want a modern, developer-friendly Doppler replacement with a clean web dashboard, instant local CLI injection (`infisical run -- npm run dev`), native GitHub Actions/Vercel/Kubernetes sync, point-in-time secret rollback, and built-in pre-commit leak scanning. Choose HashiCorp Vault (`hashicorp/vault`, 36.4k stars, BSL-1.1) or its 100% open-source Linux Foundation MPL-2.0 fork OpenBao (`openbao/openbao`, 8.5k stars) when your security architecture centers on programmable HCL policy paths, Transit encryption-as-a-service, and short-lived dynamic IAM/PostgreSQL credentials.
How do Mozilla SOPS and External Secrets Operator eliminate $2,150+/mo commercial secrets manager bills?
Commercial secrets managers like Doppler Team/Enterprise ($21/user/mo) and HCP Vault Dedicated charge $2,150+/month for a 100-developer organization. Platform teams achieve zero-licensing-cost GitOps security by encrypting YAML/`.env` values directly in Git using CNCF Mozilla SOPS (`getsops/sops`, 23.4k stars, MPL-2.0) backed by `age` or cloud KMS keys, or by self-hosting Infisical/OpenBao paired with CNCF External Secrets Operator (`external-secrets/external-secrets`, 6.9k stars, Apache-2.0) for ~$115/month (-94.6%).
