In their own words
Doppler
Doppler is a secrets manager for storing and managing sensitive application secrets through a dashboard, API, and command-line tool. It centralizes secret management with config syncs, secret referencing, and automatic rotation on eligible plans. Its MCP server lets AI agents request secrets natively, and Doppler says per-seat pricing adds no fees for AI agents or other non-human identities. Developers can use a CLI, SDKs, API, webhooks, 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 encrypts and tokenizes secrets using AES-256-GCM and is SOC 2 and ISO 27001 certified. Deployment is available in the cloud or on-prem. The Developer plan is free for three users, with additional users at $8 a month. Team costs $21 per user per month and is free for 14 days. Enterprise pricing is custom.
