## 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.
