Doppler vs KeyEnv

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.

KeyEnv manages environment variables and secrets across development workflows. Its CLI lets teams run, inject, and manage secrets from the terminal, while separate development, staging, and production configurations allow environment-specific overrides. A scanner checks for hardcoded keys, tokens, and passwords across more than 149 patterns. KeyEnv can schedule PostgreSQL and MySQL credential rotation using a two-secret approach intended to avoid downtime. Integrations include SDKs, GitHub Actions, Bitbucket Pipelines, serverless tools, and frameworks such as Next.js, Django, Laravel, Spring Boot, and Rails. The maker says secrets are encrypted on the device with AES-256-GCM and that it cannot access encryption keys or plaintext secrets; data in transit uses TLS 1.3, with Argon2id for key derivation. Access controls include roles, environment isolation, revocable scoped tokens, and audit logs. KeyEnv runs on Linux, macOS, web, API, and self-hosted deployments. The Free plan includes up to three projects and 100 secrets per environment. Team is $3.33/user/mo (annual) or $4.00 per user/month; new accounts get a 14-day Team-feature trial without a credit card.
