What you gain
- ✓No per-secret pricing on HashiCorp Cloud Platform
- ✓Full control over secret management without HCP dependency
- ✓No vendor lock-in on your secrets infrastructure
- ✓Self-hosted Vault with identical open source codebase
What you give up
- △No managed auto-unseal with cloud KMS integration
- △No HCP Vault Secrets for SaaS-based secret distribution
- △No built-in Sentinel policy enforcement for secret access
- △No managed audit logging with compliance-ready reports
Switching Cost
HashiCorp Vault Cloud has low lock-in because Vault is open source. Self-hosting Vault gives you the same API, the same secrets engines, and the same policies. The migration is straightforward: export secrets, spin up Vault, import. Solo devs can self-host in a few hours. Teams with complex policies, dynamic secrets, and PKI infrastructure should budget a week. The hidden cost is the unsealing process: Vault Cloud handles auto-unseal automatically, and self-hosted Vault requires configuring a cloud KMS or Shamir's Secret Sharing for unsealing, plus operational procedures for when Vault seals unexpectedly.
