history
Project history and usage
Teller is a Rust command-line tool for developer-oriented secrets workflows. Its upstream README presents it as an open-source universal secret manager for developers that keeps secret lookup, process execution, redaction, scanning, and provider syncing in the terminal.
Project history
The public GitHub repository was created in March 2021 and the earliest listed release, v0.5.0, was published the same day. The project reached a v1.0.0 release in April 2021 and continued as a small but visible cloud-native secrets utility.
Adoption history
Teller's adoption is mostly in the developer-tooling and DevSecOps niche rather than as a platform service. Package-manager coverage in Homebrew and Nix reflects its role as a local CLI that developers install into shells, CI jobs, and workstation bootstrap scripts.
How it is used
The README centers usage on a `.teller.yml` file that maps providers such as HashiCorp Vault, AWS Secrets Manager, Google Secret Manager, dotenv files, and other stores. Common commands include `teller run` for subprocess environment injection, `teller show`, `teller sh`, `teller env`, `teller scan`, `teller redact`, `teller template`, and provider copy/write/delete operations.
Why package nerds care
For package nerds, Teller is interesting as a small CLI that bridges secret managers and Unix process environments without committing secrets to `.env` files, shell history, or dotfiles. It sits in the same practical toolbox as direnv, dotenv loaders, vault CLIs, and secret scanners.
Timeline
- 2021: GitHub repository created and v0.5.0 released.
- 2021: v1.0.0 released.
- 2024: README copyright line and latest GitHub release metadata show continued maintenance through the v2 series.
Related projects
- Teller integrates with secret stores such as HashiCorp Vault, AWS Secrets Manager, Google Secret Manager, SSM, Consul, and dotenv-style files.
- It overlaps with local environment tools and CI secret-scanning workflows, but its upstream positioning is specifically terminal-first secret access and redaction.
