What is Doppler?

Doppler is a secret management platform that helps developers securely store, manage, and sync environment variables and sensitive credentials across applications, teams, and environments. It simplifies secret management by providing a centralised, encrypted, and version-controlled solution, eliminating the risks of hardcoded secrets and manual configuration.

Doppler integrates seamlessly with cloud platforms, CI/CD pipelines, and Kubernetes, ensuring that applications always have access to the latest secrets without requiring manual updates.
