## Project history and usage

cntb is Contabo's command-line interface for managing Contabo VPS, VDS, and related cloud products.

### Project history

The official README describes cntb as a CLI for managing Contabo products and shows generated API-style commands for images and compute instances.

### Adoption history

The official README documents prebuilt releases for Windows, macOS, and Linux, while the input package facts show Homebrew and Nix packaging.

### How it is used

Users configure cntb once with OAuth2 client ID, client secret, API user, and API password from the Contabo Customer Control Panel, then run commands such as cntb get images.

### Why package nerds care

cntb gives package users a provider-specific cloud CLI that can be installed like other Unix tools while still wrapping Contabo's API surface.

### Timeline

- 2026: GitHub releases page lists v1.6 as latest on March 25, 2026.

### Related projects

- The official Makefile shows API client generation from https://api.contabo.com/api-v1.yaml, tying the CLI to Contabo's public API specification.
