Platform Secrets
HashiCorp Vault centrally manages the platform's secrets, dynamic credentials, and encryption.
Objective
A single audited source of truth for every credential the platform consumes — database passwords, cloud API keys, OAuth clients — with policy-controlled access and rotation.
Open Source Alternatives
HashiCorp Vault (BSL) — 10 / 10
The deepest secrets engine. Dynamic database credentials, transit encryption, PKI, audit log, fine-grained policies, broad ecosystem of integrations. BSL-licensed since 2023 (source-available, not pure OSS), which is the only real concern — the technology itself is unmatched.
OpenBao — 8 / 10
OSS fork of Vault under MPL-2.0 after HashiCorp’s relicense. Same architecture, growing community. Right pick when the BSL license is the deal-breaker. Ecosystem still trails Vault but catching up.
Infisical (OSS) — 7 / 10
Modern OSS secrets platform. Lighter feature set, simpler UX, narrower scope than Vault. Excellent for app-team-driven secret management; weaker for dynamic credentials and PKI.
Vaultwarden / Bitwarden (OSS) — 6 / 10
Different audience (humans, not services). Personal/team credentials, not platform secrets.
Sealed Secrets — 6 / 10
Encrypts secrets-in-Git — different model. Useful as a complement to Vault for declarative GitOps; not a replacement for the broker.
SOPS — 6 / 10
Mozilla’s secrets-in-files encryption tool. Same complementary role as Sealed Secrets — not a secret broker.
Conjur (OSS) — 6 / 10
CyberArk’s OSS secrets manager. Smaller community than Vault; aligns with the CyberArk enterprise offering.
Managed SaaS Alternatives
HCP Vault — 9 / 10
HashiCorp’s managed Vault. Same engine, hosted by HashiCorp. Premium.
AWS Secrets Manager — 8 / 10
AWS-native secrets store. Tight IAM integration; locked to AWS.
GCP Secret Manager — 8 / 10
GCP-native equivalent. Same story — strong inside GCP, locked to it.
Azure Key Vault — 8 / 10
Azure-native. Adds key management to the secrets story.
Doppler — 7 / 10
Managed secrets SaaS. Premium, app-team-focused, slick DX.
Infisical Cloud — 7 / 10
Managed Infisical. Same advantage profile as OSS; hosted.
1Password Connect — 7 / 10
Org password manager exposed as a secrets API. Limited to 1Password-managed orgs.
Akeyless — 7 / 10
Managed secrets platform with vaultless DFC architecture. Premium SaaS.

Top in this category
Top OSS pick: HashiCorp Vault (deepest engine) or OpenBao (when the license matters). Top managed pick: HCP Vault or cloud-native (AWS/GCP/Azure).
Vault remains the unambiguous technical top for breadth and depth. This stack’s pick is the category top. OpenBao becomes the right choice if and when the BSL becomes a hard blocker.
