Keyline is a secrets manager designed for small development teams to securely share environment variable files, such as .env files. It addresses common issues teams face when sharing sensitive credentials through insecure channels like chat threads or shared drives, which can lead to unencrypted, persistent copies and out-of-date information. Keyline aims to eliminate these risks by providing a simple way to share secrets with strong security measures.
The platform operates with zero-knowledge principles and uses client-side AES-256 encryption, ensuring that even the service itself cannot read stored keys. Users can share their .env files with a single command, and Keyline natively supports the .env format, allowing teams to integrate it into their workflow without making changes to their application code. Access to secrets can be locked down per environment, and every change is audited to maintain a record of who accessed or modified credentials and when.
Keyline is hosted, meaning it manages the storage of secrets for its users while maintaining security through encryption. It is particularly aimed at small teams and solo developers, with a free tier available for individual users. The tool is intended to prevent leaks, outdated credentials, and the lack of audit trails that can arise from less secure sharing practices.
