About Doppler

Doppler is a commercial secrets management platform that stores API keys, passwords and environment variables in one place and delivers them to the apps and people that need them. It is aimed at engineering teams that want to stop passing secrets around in files and chat, and it now extends this to AI agents and automated workflows.

Secrets stay centralized, rotated and auditable wherever they are used, with native integrations for cloud platforms, Kubernetes, CI/CD systems, webhooks and SDKs. An MCP server lets AI agents request secrets directly without hardcoded credentials, and every access by a human or agent is logged. The vendor says it is SOC 2 and ISO 27001 compliant and supports both on-prem and cloud deployments of the applications it serves.

Doppler is proprietary and delivered as a hosted service. It uses user-based pricing without extra charges for non-human identities, and visitors can start for free, book a demo or view a pricing page.
