What Doppler is
Doppler is a secrets manager for developers, DevOps and security teams, and automated workflows. It centralizes sensitive application secrets through a dashboard, API, and command-line tool, with config syncs, secret referencing, and automatic rotation on eligible plans. Its MCP server lets AI agents request secrets without custom scripts or hardcoded credentials; Doppler says its per-seat pricing does not add fees for AI agents or other non-human identities. Tools include a CLI, SDKs, webhooks, an API, and a VS Code extension with two-way sync. Listed integrations include AWS Secrets Manager, Terraform Cloud, GitHub Actions, Kubernetes, GCP Secret Manager, Azure Key Vault, Vercel, and Okta. Security controls include scoped tokens, fine-grained access, breach detection, encrypted fallback files, and trusted IP allow lists. Doppler says it uses AES-256-GCM encryption and holds SOC 2 and ISO 27001 certifications. Deployment is available in the cloud or on-prem. The Developer plan is free for three users; each additional user is $8 per month. Team costs $21 per user per month and is free for 14 days.
