HashiCorp Vault → Infisical
What it saves, what actually moves, what you rebuild — and the thing that catches people.
What it costs, and what it saves
Infisical's MIT core is free to self-host. Against HCP Vault at $450–$1,150 a month the saving is the whole subscription; against self-hosted Vault the saving is operational time rather than money.
Moves cleanly
The secret values. Everything structural is different.
You rebuild
Access policies, auth methods and any dynamic secret engine. Infisical's model is simpler and does not map one-to-one.
What HashiCorp Vault costs you today
The community edition is free. HCP Vault Dedicated starts around $450/month for a development extra-small cluster; a production Essentials Small cluster is roughly $1,150/month before per-client fees near $72.92/month, and a standard small cluster with 50 clients runs about $5,000/month. Enterprise self-managed licences are negotiated and land well above that. Figures checked 2026-07-31 — note the most detailed public breakdowns are published by competitors, so verify against HashiCorp directly before you budget.
What actually holds you in
Lower than the operational effort implies, and this is the good news. Vault's HTTP API is well documented and OpenBao is a direct fork, so moving there is close to a drop-in — the paths, policies and tokens are the same shape. What actually holds you is the surrounding machinery: auto-unseal wired to a cloud KMS, dynamic database engines, PKI issuance, and the Terraform and Kubernetes integrations built around Vault's specific behaviour. Teams that use Vault as a key-value store move in an afternoon; teams using dynamic credentials and PKI have a project.
What you are moving to
Infisical was built on the premise that Vault is too hard for what most teams need, and it shows: a clean web UI, a CLI that injects secrets into a process without writing them to disk, native Kubernetes and GitHub Actions integrations, and secret scanning to catch leaks before they are committed. It covers the common ninety per cent — storage, rotation, environment scoping, access control — without the unsealing ceremony. Around 28.5k stars. One precision worth stating: the core is MIT, but everything under the `ee/` directory is licensed separately as enterprise, so check which side of that line the feature you need falls on before you build around it.
Free and self-hostable for the MIT core; hosted plans and enterprise features are paid.
Infisical strengths
- By far the best developer experience in this comparison
- CLI injects secrets into a process without touching the filesystem
- Built-in secret scanning catches leaks before they ship
- Self-hostable, with Kubernetes and CI integrations that work out of the box
What you give up
- Enterprise features live behind an `ee/` carve-out — not a pure MIT product
- No equivalent of Vault's dynamic database credentials or PKI engine
- Single-vendor governance, the same structural risk that moved Vault to BSL
- Younger, with a shorter track record under real load
The migration, step by step
- 1List which Vault features you actually use — most teams use it as a key-value store and nothing more
- 2If dynamic database credentials or PKI appear on that list, stop: Infisical does not replace them
- 3Deploy Infisical, create projects and environments matching your Vault paths
- 4Export from Vault with the CLI and import via Infisical's CLI
- 5Swap the injection mechanism — Infisical injects into a process rather than being read via API
The gotcha
Infisical has no dynamic database credentials and no PKI engine. If you moved to Vault specifically for short-lived database passwords, this migration removes the reason you adopted it.
When to stay on HashiCorp Vault
You use dynamic secrets, transit encryption, or Vault as an internal certificate authority.
