What is Teller Secrets?

Editorial review
Teller is an open-source, cloud-native secrets management tool that lets developers access and manage secrets directly from the terminal. It provides a unified CLI interface across multiple vault providers including HashiCorp Vault, AWS Secrets Manager, Google Secret Manager, and Azure Key Vault. Teller eliminates the need for hardcoded secrets, scattered .env files, or visible exports in shell history. It supports secret scanning, drift detection between providers, cross-provider syncing, and log redaction, making it a comprehensive shift-left security tool for DevSecOps pipelines. Written in Rust with 3.2k GitHub stars under Apache-2.0.
