HashiCorp Vault has changed its license from MPL 2.0 to BuSL, leading many companies and developers to look for alternative solutions. Infisical is an open-source secret management platform that provides comprehensive tooling for secret management, including encrypted version-controlled secret storage, dynamic secret management, integrations across infrastructure, secret scanning, leak prevention, and certificate lifecycle management. It supports a wide range of companies and organizations and has a strong community of developers. Infisical's core functionality is available under the MIT license, making it easy to integrate without organizational approval processes. The platform offers multiple pricing options, including an open-source version with unlimited instances and users, as well as more advanced features available through an enterprise license. Mozilla SOPS is another tool that provides a simple and secure way to manage secrets, but its limitations make it less suitable for complex use cases. Cyberark Conjur is a solution designed to fight secret sprawl and integrate with DevOps methodologies, providing robust security framework and managing application identities and securing access to cloud resources. However, its high cost and complexity might be a barrier for small businesses or startups. Building an in-house secrets management tool can offer customization, but it also comes with challenges such as resource-intensive development, ongoing maintenance, audit, and compliance challenges, security expertise requirement, lack of external support, and training concerns. Infisical is considered a perfect HashiCorp Vault replacement if you are looking for a developer-focused solution that will last many years ahead, value transparency, and want to try before you buy.
