Doppler

Doppler is a secrets management platform that gives engineering teams a single, secure place to store and sync API keys, database credentials, and other environment variables across every environment and service, replacing the common but risky practice of scattering secrets across .env files, Slack messages, and shared documents. Developers connect Doppler to their local development environment, CI/CD pipeline, and production infrastructure, and secrets are injected automatically wherever they're needed without ever being committed to a git repository or copy-pasted between team members insecurely. Every secret change is versioned and auditable, so teams can see exactly who changed a value and when, and roll back to a previous version if a bad change breaks a deployment. Doppler's integrations cover popular cloud providers, CI/CD tools, and container orchestration platforms, meaning secrets stay in sync across a company's entire deployment pipeline rather than needing to be manually updated in five different places whenever a credential rotates. Role-based access controls let teams restrict which secrets specific engineers or services can access, which matters for limiting blast radius if a single service or developer account is compromised. Doppler is used by startups and engineering teams of all sizes that have outgrown ad hoc secret handling and want centralized, auditable secrets management without building that infrastructure themselves.
