Migrating to Infisical for open-source secret management
Infisical offers an MIT-licensed alternative to HashiCorp Vault and Doppler, featuring client-side end-to-end encryption and self-hosting. The platform provides developer-friendly SDKs, Kubernetes operators, and a free tier covering up to 5 identities and 3 projects.
Infisical provides an MIT-licensed core that allows teams to migrate away from HashiCorp Vault and Doppler. HashiCorp Vault uses the BUSL-1.1 license, which makes some open-source users cautious. Doppler remains a cloud-only platform, so it fails to meet the needs of teams with strict data residency requirements or those needing air-gapped deployments. Infisical uses client-side end-to-end encryption by default, meaning the platform cannot decrypt secrets. This architecture provides a stronger security guarantee than Doppler, because Doppler encrypts secrets at rest on its servers but holds the encryption keys. While Doppler’s Developer plan is free for 3 users, the Team plan costs $21 per user per month and adds SAML SSO and automatic rotation. Infisical’s GitHub repository has accumulated momentum as teams look for alternatives to Doppler. The platform is written in TypeScript and provides a way to sync secrets to platforms like GitHub and Vercel.
Infisical provides developer-friendly SDKs and a Kubernetes operator to deliver secrets to workloads. The platform handles secret rotation and includes secret scanning to catch leaks. Infisical supports dynamic secrets for common services like PostgreSQL and MySQL. However, it lacks a transit engine equivalent to the encryption-as-a-service provided by HashiCorp Vault. This capability difference distinguishes it from the more mature HashiCorp Vault. Teams wanting to maintain secrets within their own perimeter or comply with strict data residency requirements often select the Infisical self-hosted option because it allows them to keep sensitive data away from third-party cloud providers.
The platform manages identity through various methods, including Kubernetes, GCP, Azure, and AWS authentication. It also provides Honey Tokens to act as tripwires that alert a team if an attacker uses decoy credentials. For AI workloads, the Infisical Agent Vault acts as a proxy to broker access to external APIs, which prevents agents from holding real credentials. Infisical provides Privileged Access Management (PAM) to decouple user identity from infrastructure credentials. Users authenticate with SSO to get just-in-time access to resources like SSH servers and PostgreSQL. The system includes session recording to capture and replay privileged sessions. While Infisical supports dynamic secrets, it does not match the depth of HashiCorp Vault, which generates unique, short-lived credentials for many backends. Does your organization require the advanced encryption-as-a-service capabilities of a transit engine?
Teams can migrate to Infisical by deploying it alongside Vault and syncing secrets into the new system. If you move from Vault, you can use Infisical’s migration tooling for KV import, Kubernetes auth shapes, and policy translation. You should evaluate your machine identity needs before committing to a per-identity pricing model. Infisical is the best choice for teams wanting open-source secrets management with modern developer experience and self-hosting flexibility.

The Infisical free tier covers up to 5 identities and 3 projects. For more robust needs, the Pro plan costs $18 per identity per month. The Advanced tier costs $40 per identity per month and adds dynamic secrets and SOC 2 Type II reporting. Infisical also provides a Kubernetes operator and specialized SDKs for Node, Python, Go, Ruby, Java, and .NET. For users requiring advanced access, the PAM features allow for web access to SSH, PostgreSQL, Redis, and Windows RDP resources directly from the browser.
