Best Open-Source HashiCorp Vault Alternatives (2026)

3 self-hostable, open-source projects that replace HashiCorp Vault — without BSL relicensing and enterprise costs. Each is scored for how hard it is to self-host, with one-click deploy options where they exist.

HashiCorp's move to the BSL (Business Source License) plus enterprise pricing pushed many teams to look for a freely-licensed path. The good news is there's a true drop-in: OpenBao is a fork of Vault itself, now under the Linux Foundation.

Our picks at a glance

Easiest to self-host
SOPS

Difficulty 1/5, no server to run — it just encrypts files in Git with KMS/age/PGP.

Most powerful
OpenBao

As a fork of Vault, it carries the full dynamic-secrets engine and API rather than a subset.

Most active
SOPS

At ~22,000 stars it has the most momentum of the three.

Best managed option
Infisical

Infisical is the only option here with an official managed cloud (managed:yes).

What to look for: Decide whether you need a full dynamic-secrets engine and API (server-based) or just encrypted secrets in Git (serverless). For a Vault replacement, API/storage-backend compatibility and a credible governance model matter most; for simpler needs, a file-encryption tool may be all you require.

    SOPS
    Self-host: Effortless

    Encrypt files in Git with KMS/age/PGP — secrets management without a server

    22k Go MPL-2.0 1 month ago
    How it compares to HashiCorp Vault
    • Not a centralized secrets server: no dynamic secrets, leasing, revocation, or audit log like Vault
    • Requires an external key provider (KMS/age/PGP) and disciplined key management
    • No UI, access policies, or web dashboard
    • Suited to config-file secrets in Git, not runtime secret brokering

    Self-host: Moderate

    Open-source secrets management platform for developers and teams

    19k TypeScript MIT 3 days ago
    How it compares to HashiCorp Vault
    • Core is MIT but a number of features live under an enterprise (ee) license requiring a paid plan
    • Less battle-tested than Vault for low-level cryptographic/dynamic-secret workloads
    • Self-hosted instances do not include all features available in the paid cloud tier
    • Smaller plugin/integration catalog than HashiCorp Vault

    OpenBao
    Self-host: Involved

    Open-source secrets management forked from HashiCorp Vault under the Linux Foundation

    6.5k Go MPL-2.0 26 days ago
    How it compares to HashiCorp Vault
    • Younger project with a smaller ecosystem than HashiCorp Vault; some Vault Enterprise features and integrations are missing
    • No first-party managed/cloud offering equivalent to HCP Vault
    • Operating a production HA cluster (storage backend, unsealing, auto-unseal) requires real expertise
    • Documentation and third-party tutorials still maturing relative to Vault's
    RepoDetails & deploy →

The verdict

If you're leaving Vault specifically over the license, OpenBao is the closest thing to a drop-in since it's forked from Vault under the Linux Foundation. For a simpler, server-free approach, SOPS is the easiest; for a managed developer-friendly platform, choose Infisical.

HashiCorp Vault alternatives — frequently asked questions

Is there a drop-in open-source replacement for HashiCorp Vault?

OpenBao is the closest. It's a direct fork of Vault, MPL-2.0 licensed and governed by the Linux Foundation, so its API and concepts carry over.

Which Vault alternative is easiest to set up?

SOPS, at difficulty 1/5. It needs no server — it encrypts files in place using KMS, age, or PGP, so you commit encrypted secrets straight to Git.

Why are people moving off Vault?

HashiCorp relicensed Vault under the BSL, and enterprise features carry significant cost. OpenBao (MPL-2.0), SOPS (MPL-2.0), and Infisical (MIT) are all permissively or weak-copyleft licensed.

Do I need to run a server for secrets management?

Not necessarily. SOPS is serverless and encrypts files directly in Git. OpenBao and Infisical are server-based platforms if you need dynamic secrets, access policies, and an API.

Which Vault alternative has managed hosting?

Infisical offers an official managed cloud (managed:yes). OpenBao and SOPS are self-host/self-managed only.

What licenses do these alternatives use?

OpenBao and SOPS are MPL-2.0; Infisical is MIT. All three avoid the BSL that prompted the move away from Vault.
