Vault is still the most capable secrets platform, but BUSL relicensing and the IBM acquisition have teams re-evaluating. Here are four strong alternatives — open-source, cloud-native, and SaaS — ranked by why you're leaving.
HashiCorp Vault remains the most capable secrets management platform around — but it's no longer the obvious default. In August 2023, HashiCorp relicensed Vault from MPL 2.0 to the Business Source License (BUSL), restricting production use by competitors1. The subsequent IBM acquisition has only accelerated the re-evaluation. And if you've operated Vault in production, you already know the pain points: operational overhead, a steep learning curve, and low developer adoption1.
The right alternative depends on why you're leaving:
Here's how the top options stack up.
Infisical is the strongest pick for teams that want a lighter, more ergonomic Vault replacement they can self-host. It's MIT-licensed, runs on Postgres, and is designed for day-one time to value1. Where Vault demands significant operational expertise just to stand up, Infisical prioritizes developer experience — a clean CLI, dashboard, and straightforward secret injection.
You get both self-hosted and cloud options. The open-source core is free; cloud tiers add managed hosting with per-user pricing, though service accounts have usage limits on the cloud plan4. SOC 2 compliance was in progress as of the latest comparison4. Self-hosting takes roughly 1–3 hours, while cloud setup is 10–15 minutes4.
The trade-off: Infisical doesn't match Vault's depth in dynamic secrets or encryption-as-a-service. If you rely heavily on those features, look at OpenBao instead (more below).
Best for: Teams leaving Vault over licensing or operational complexity who want an open-source, self-hostable alternative with better developer ergonomics.
If your infrastructure already lives in AWS, consolidating secrets management onto the same cloud is hard to beat. AWS Secrets Manager is fully managed with zero operational overhead, integrates natively with IAM, ECS, Lambda, and other AWS services, and handles automatic rotation for supported databases3.
Pricing is $0.40 per secret per month plus $0.05 per 10,000 API calls3. That's predictable for modest secret counts but can add up at scale — something to model against your actual usage.
The trade-off is lock-in. You're buying into the AWS ecosystem, and multi-cloud or hybrid setups will need a different tool or a second secrets manager alongside it. There's also no self-hosted option.
Best for: AWS-aligned organizations consolidating secrets on a single cloud with zero operational overhead.
Azure Key Vault is the natural choice for teams already invested in Azure and Entra ID (formerly Azure AD). It provides managed secrets, keys, and certificates in a single service, with HSM-backed key storage for compliance-sensitive workloads2.
Pricing is per-operation3, which works well for lower-volume key management but requires careful modeling for high-throughput secret retrieval. Native integration with Azure services — App Service, Functions, AKS — means minimal wiring for existing Azure shops.
Like AWS Secrets Manager, this is a single-cloud play. If you run multi-cloud or need dynamic secrets, you'll outgrow it.
Best for: Microsoft-ecosystem teams wanting managed secrets, keys, and certificates in one service with Entra ID integration.
Doppler is the developer-favorite for hosted secrets and config sync2. It's a fully managed SaaS with a polished CLI and dashboard, flat per-user pricing with unlimited service accounts, and built-in SOC 2 Type II, HIPAA, and GDPR compliance4. Setup takes 5–10 minutes4.
Pricing starts at $7/seat/month for team plans, with a free tier for small projects3. The flat per-seat model is simpler to budget than per-secret pricing, especially as your secret count grows.
Compared to Infisical, Doppler wins on operational simplicity — no servers to run, no Postgres to manage. Infisical wins on control and open-source flexibility4. If you don't need self-hosting and want the fastest path to good secrets hygiene, Doppler is the pick.
Best for: Growth-stage teams prioritizing developer experience and operational simplicity over self-hosting.
Vault is included here as the baseline you're comparing against, and it still does things no alternative matches. Dynamic secrets — generating short-lived credentials on demand for databases, cloud providers, and more — are Vault's signature capability. Encryption-as-a-service, a deep authentication ecosystem (LDAP, OIDC, Kubernetes, AWS IAM, and dozens more), and multi-cloud support remain best-in-class.
The trade-offs are real, though: BUSL licensing creates uncertainty for some organizations1, operational complexity is high, and developer adoption tends to lag without significant investment in tooling and onboarding.
Best for: Teams that need dynamic secrets, encryption-as-a-service, or deep multi-cloud auth — and can absorb the operational cost.
| Dimension | Infisical | AWS Secrets Manager | Azure Key Vault | Doppler | HashiCorp Vault |
|---|---|---|---|---|---|
| License | MIT | Proprietary | Proprietary | Proprietary | BUSL 1.1 |
| Hosting | Self-host or cloud | AWS-managed | Azure-managed | Hosted SaaS | Self-host or cloud |
| Pricing | Free OSS / paid cloud | $0.40/secret/mo | Per-operation | From $7/seat/mo | Free OSS / Enterprise |
| Dynamic secrets | Limited | No | No | No | Yes |
The core trade-off: cloud-native managers (AWS, Azure) and hosted SaaS (Doppler) buy simplicity at the cost of lock-in and feature depth. Open-source alternatives (Infisical) buy control and licensing clarity at the cost of some advanced features. Vault buys maximum capability at the cost of operational complexity and licensing uncertainty.
If your primary concern is the BUSL license and you want the lowest-friction migration path, OpenBao deserves a look. It's an MPL-2.0 Linux Foundation fork that's API-compatible with Vault2, meaning you can migrate with minimal code changes while staying on a truly open-source license. You keep Vault's dynamic secrets and auth ecosystem — you just lose the BUSL licensing question.
OpenBao isn't a separate product pick here because it's a fork, not a redesign. But for teams whose only problem with Vault is the license, it's the shortest path.
