HashiCorp Vault Alternatives: 8 Secrets Managers Compared (2026)

Why teams look past Vault

HashiCorp Vault is still the most capable secrets platform in the category. The reason a "Vault alternative" search exists at all is mostly licensing. In 2023 HashiCorp moved Vault to the Business Source Licence, which is source-available rather than OSI-approved open source, and the company is now part of IBM. For teams whose compliance or procurement rules require open licensing, or who simply do not want their secrets layer controlled by a single vendor after that precedent, that was the cue to look elsewhere. Operational complexity and Enterprise pricing do the rest.

This comparison stays inside the lane Vault actually occupies: storing and serving application and machine secrets. That scoping matters. Privileged access management tools rank for these searches too, but they solve a different problem for a different buyer, and we keep them out of the scored table for that reason. More on them below.

The eight alternatives at a glance

Two OSI-open self-host options, the three cloud-native managers, two independent SaaS tools, and one Kubernetes-native pattern. They are grouped into three tables below because they answer the question in three different ways. Pricing is indicative and based on published rates; confirm current figures before you commit.

Open source, self-hosted

Cloud-native managers

Independent SaaS and Kubernetes-native

Open source, self-hosted: OpenBao and Infisical

OpenBao is the obvious starting point if the licence is why you are leaving Vault. It is the MPL-2.0 fork, governed under the Linux Foundation, API-compatible with Vault, and therefore the lowest-friction move: much of your existing Vault tooling points at the new endpoint and keeps working. You give up HashiCorp's commercial Enterprise features and first-party support, and you operate it yourself. We cover the trade-off in detail in our OpenBao vs HashiCorp Vault comparison.

Infisical is the alternative for teams that found Vault heavier than their problem warranted. Its core is MIT-licensed and it is built around developer ergonomics: syncing secrets and configuration across environments, a clean dashboard, and integrations that take minutes rather than days to wire up. It is open-core, so some enterprise features sit under a source-available licence in a separate directory; read that split before you depend on a given feature. For most application-secret use cases, it is the faster tool to adopt.

Cloud-native: AWS, Azure, and Google

If your workloads live entirely inside one cloud, that cloud's own manager is usually the pragmatic choice. AWS Secrets Manager, Azure Key Vault, and Google Secret Manager each integrate natively with their platform's identity system, need no extra infrastructure to run, and bill per secret or per operation rather than per seat. For an AWS-only shop, Secrets Manager at roughly $0.40 per secret per month is hard to argue against on convenience grounds.

The cost is structural. Each one ties your secrets layer to a single vendor, and none of them is a good fit for a multi-cloud or hybrid estate, where you would end up operating three different secrets systems with three different access models. That multi-cloud pain is exactly the gap a platform-neutral tool like OpenBao or Infisical fills, and it is the main reason teams run a dedicated secrets manager on top of cloud infrastructure they already pay for.

Independent SaaS: Doppler and Akeyless

Doppler is the developer-favourite for managing secrets and configuration as a hosted service. It is strongest at the workflow most teams actually have: keeping environment variables and API keys in sync across local, staging, and production without a self-hosted server to maintain. It has a free tier and scales by seat. The trade-off is that it is proprietary and hosted, so it suits teams comfortable with a SaaS secrets layer rather than those who need to self-host.

Akeyless occupies the enterprise-but-not-PAM slot. It is a SaaS-first platform built around a vaultless, distributed-fragments approach to key material, aimed at organisations that want managed secrets and dynamic credentials at scale without operating Vault themselves. It is sales-led rather than self-serve, which tells you the intended buyer: a security or platform team standardising secrets across a large estate.

Two more hosted options belong in the same conversation without earning a scored slot here: Bitwarden Secrets Manager and 1Password Secrets Automation both extend a well-known password manager into developer secrets. They are reasonable picks for teams already standardised on either vendor, but their machine-secrets feature depth and adoption sit below the eight above for this specific use case.

Kubernetes-native: External Secrets Operator

External Secrets Operator is not a secrets store, and including it needs that caveat. It is an Apache-2.0 Kubernetes operator that syncs secrets from a backing store, which can be AWS Secrets Manager, Azure Key Vault, Google Secret Manager, OpenBao, or Vault, into native Kubernetes secrets your workloads consume. If your real question is "how do I get secrets from my chosen store into my cluster cleanly," ESO is the standard answer, and it pairs with rather than replaces the other tools here. Its high commercial search intent reflects how central Kubernetes secret delivery has become.

Also consider: enterprise PAM and machine identity

These names carry large search volume and come up constantly, but they sit in adjacent categories with a different buyer. If your requirement is privileged human access rather than application and machine secrets, start here instead of the table above.

• CyberArk is the privileged access management leader; its Conjur product reaches into machine secrets, but the core platform governs admin access, session recording, and credential vaulting for privileged human accounts.
• Delinea (its Secret Server product, formerly Thycotic) and BeyondTrust are the other two PAM heavyweights, with the strongest overlap into machine-secret storage among the PAM vendors.
• Venafi and Keyfactor address machine identity and certificate lifecycle rather than secrets storage. Reach for them when your problem is managing TLS certificates and keys at scale, not application credentials.

Decision framework

Want the open Vault with minimal migration friction: OpenBao. It is the licence-clean continuation of the platform you already know.

Want a lighter, developer-first secrets tool: Infisical if open source and self-host matter, Doppler if you are happy with a hosted service.

Single-cloud and want the least operational overhead: your cloud's native manager, paired with External Secrets Operator if you run Kubernetes.

Large estate, want managed scale without running Vault: Akeyless.

Your actual need is privileged human access: a PAM vendor (CyberArk, Delinea, BeyondTrust), not a secrets manager.

Bottom line

There is no single best Vault alternative, because the teams leaving Vault are leaving for different reasons. If the licence is the trigger, OpenBao is the clean answer and the easiest migration. If Vault was always heavier than you needed, Infisical or Doppler will fit better. If you live in one cloud, that cloud's manager plus External Secrets Operator is the low-overhead path, and Akeyless is the managed-at-scale option for everyone else.

One architectural note that cuts across all of them: if you are choosing a secrets manager to serve AI agents, the manager alone is not enough, because every tool here hands the secret to whatever authenticates. Put your chosen store behind a credential proxy so the agent never holds the secret. We cover that pattern and the open-source tools that implement it in the credential vaults for AI agents radar.

Why look for a HashiCorp Vault alternative at all?

The main trigger is the 2023 licence change. HashiCorp moved Vault to the Business Source Licence (BUSL-1.1), which is source-available rather than OSI-approved open source, and HashiCorp is now an IBM company. Teams with compliance or procurement rules that require open-source licensing, or who are wary of single-vendor control, started looking for alternatives. The other triggers are ordinary: Vault's operational complexity, its Enterprise pricing, and the pull of a cloud provider's native manager when all your workloads already live there.

What is the closest drop-in replacement for HashiCorp Vault?

OpenBao. It is a fork of Vault created after the relicensing, governed under the Linux Foundation and released under MPL-2.0. It keeps Vault's API and command surface, so most existing clients, Terraform providers, and integrations work against it with little change. The gap is at the high end, where some of HashiCorp's commercial Enterprise features are not yet at parity. We cover the head-to-head in our dedicated OpenBao vs HashiCorp Vault comparison.

Should I just use my cloud provider's secrets manager?

If your workloads live entirely in one cloud, usually yes. AWS Secrets Manager, Azure Key Vault, and Google Secret Manager integrate with that platform's IAM, require no extra infrastructure to run, and bill per secret or per operation. The reasons not to are multi-cloud or hybrid estates, where you would end up managing three different secrets systems, and the lock-in of tying your secrets layer to one vendor. A platform-neutral tool like OpenBao or Infisical avoids both.

Is Infisical or Doppler better than Vault?

Better is the wrong frame; they target a different need. Vault and OpenBao are heavyweight secrets platforms with dynamic secrets, leasing, and a deep auth-method ecosystem. Infisical and Doppler optimise for developer experience: syncing application configuration and secrets across environments with minimal setup. If your problem is managing environment variables and API keys across a dev team, Infisical or Doppler will be faster to adopt. If you need dynamic database credentials and fine-grained leasing, the Vault lineage is stronger.

Where do CyberArk, Delinea, and BeyondTrust fit?

They are privileged access management (PAM) tools, which is a related but distinct category. PAM governs privileged human access to systems: session recording, credential vaulting for admin accounts, just-in-time elevation. That overlaps with secrets management at the edges, and Delinea's Secret Server and CyberArk's Conjur reach into machine secrets, but the core buyer is a security team managing human access, not a platform team managing application secrets. If that is your actual requirement, evaluate them; if you need app and machine secrets, the eight tools in the table above are the right shortlist.

Which alternative is best for AI agents?

For the storage layer, OpenBao if you want OSI-open, or your cloud's manager if you are single-cloud. But the more important point for agents is architectural: none of these tools keeps a secret out of an agent's reach on its own, because they all hand the credential to whatever authenticates. The pattern that actually defends against prompt-injection exfiltration is a vault behind a credential proxy. Our credential vaults for AI agents radar covers the open-source proxies that implement it.
