The 3 Best HashiCorp Vault Alternatives in 2026

Doppler replaces .env files with one dashboard and CLI: secrets are organised by project and environment, injected at runtime with `doppler run`, and synced to Vercel, AWS, GitHub Actions, Kubernetes and dozens of other targets. Changes are versioned and logged, and secrets can reference each other so a value is defined once. Teams mainly pick it for developer experience across local, staging and production. The Developer plan is free for up to 3 users, then $8 per extra user per month, with 10 projects, 4 environments and 3 days of activity logs. Team is $21 per user per month (14-day trial) and adds SAML SSO, role-based access, automatic secret rotation, change requests and 90 days of logs; custom roles, user groups and extra syncs are $9 per seat add-ons. Enterprise is custom and adds dynamic secrets, on-prem deployment and SCIM. AI agents and service identities do not count as seats. As of October 2026.

• Excellent CLI and local-development workflow
• Dozens of sync integrations
• Machine identities do not count as seats

Infisical stores application secrets per project and environment, injects them through a CLI, SDKs and a Kubernetes operator, and syncs them to clouds and CI providers. Its core is MIT licensed and free to self-host, which is the main reason teams choose it over closed hosted tools. Beyond secrets it offers dynamic secrets, internal certificate management (PKI), privileged access management and an Agent Vault that brokers credentials for AI agents. For secrets management, the cloud Free plan covers 5 identities, unlimited projects, 3 environments and 10 secret syncs. Pro is $20 per identity per month billed annually ($23 monthly) with SSO, versioning and point-in-time recovery; Advanced is $40 ($46 monthly) and adds dynamic secrets, custom roles and temporary access. Enterprise is custom and adds SCIM, approval workflows and HSM support. Paid plans have a 30-day trial. Supported self-hosting, including air-gapped, is an Enterprise option. As of October 2026.

• MIT-licensed core you can self-host
• Secrets, certificates and PAM in one platform
• Free cloud tier for small teams

AWS Secrets Manager stores API keys, database passwords and other secrets encrypted with KMS, controls access through IAM, and rotates credentials on a schedule using Lambda, with ready-made rotation for RDS, Aurora, Redshift and DocumentDB. Secrets can be replicated to other regions, and every access is logged in CloudTrail. It is the default for teams already running on AWS; it is less convenient for local development and for apps outside AWS, where tools like Doppler and Infisical sync secrets more easily. Pricing is $0.40 per secret per month and $0.05 per 10,000 API calls, so 50 secrets read often by a few services usually cost $20 to $30 a month. New AWS accounts get up to $200 of Free Tier credits that apply to it. AWS Systems Manager Parameter Store is the cheaper sibling for plain config: standard parameters are free, but it has no built-in rotation. As of October 2026.

• Native IAM, KMS and CloudTrail integration
• Built-in rotation for AWS databases
• Cheap at small scale with no seats
