Cirklu is a Chrome extension designed to provide developers with a secure and efficient way to manage their API keys. It utilizes AES-256 encryption to ensure that keys are stored locally and never exposed, offering features like intelligent field detection, encrypted sharing, and a command palette for quick access. The extension stands out with its zero-exposure architecture, meaning that keys are only saved when confirmed by the user, eliminating silent scanning or clipboard exposure.

The extension is ideal for solo developers, startup teams, and organizations conscious of security, as it allows for the secure sharing of temporary access to keys without compromising sensitive information. Cirklu supports over 50 platforms, including popular services like Stripe and AWS, and offers smart organization features such as auto-grouping and duplicate detection. With a focus on user privacy and data security, Cirklu provides a reliable solution for managing API keys in a fast-paced development environment.
