## Project history and usage

ATAC is a Rust terminal API client, explicitly framed by its README as a Postman-, Insomnia-, and Bruno-like client that runs in the terminal without a graphical environment. The project emphasizes being free, account-less, offline, and backed by readable versionable files.

### Project history

The repository began in February 2024 and quickly built a TUI around request collections, HTTP methods, bodies, headers, authentication, WebSocket support, environment files, import/export, themes, key bindings, and scripting. The README still describes the project as pre-1.0, with v1 and v2 TODO sections for requested polish and protocol expansion.

The v0.23.0 release in 2026 added JWT and Digest authentication, a global config file, a large rework of text inputs, graphical-protocol disabling, and more headless-environment fixes. That release also describes the project as only a few features away from v1.

### Adoption history

ATAC has unusually broad packaging for a young TUI: the upstream README documents cargo, Homebrew, Scoop, Arch, Fedora Copr, Docker, and binary releases. The supplied package metadata also lists apk, Debian, Ubuntu, Nix, pacman, Scoop, and Homebrew packaging, indicating quick uptake across developer-oriented package managers.

Its adoption story is tied to dissatisfaction with account-centric GUI API clients. The README comparison table stresses local files, offline behavior, full CLI usage, import from Postman/OpenAPI/cURL, and terminal-native operation.

### How it is used

Users install `atac` and run it from a terminal to manage request collections, send HTTP/WebSocket requests, edit request data in a TUI, store environment files, export cURL and language snippets, and import existing API-client formats. It can be used interactively, as a CLI, or embedded into editor workflows such as the documented Neovim integration.

### Why package nerds care

ATAC is a good modern example of the package-manager-friendly Rust TUI wave: one static-feeling binary, many distro channels, explicit dependency tables, and a feature pitch aimed at replacing heavyweight SaaS desktop tools with local files that can live in source control.

### Timeline

- 2024: Initial repository commits and early Rust TUI implementation.
- 2025: v0.22.0 added Postman environment import.
- 2026: v0.23.0 added JWT/Digest authentication, global config, and a major text-input rework.

### Related projects
