Introducing CBS DevTools, My All in One Developer Utility CLI

As developers, we perform dozens of repetitive micro-tasks every day: inspecting public IP addresses, formatting JSON payloads, decoding JWT tokens, generating secure passwords or UUIDs, resizing images, and checking system resources.

For the longest time, my workflow involved jumping between random web tools, online converters, bookmarked sites, or single-purpose npm packages. I wanted a faster, more secure solution: a single, local-first terminal toolkit accessible anytime with a simple 3-letter command.

That desire led me to build CBS DevTools (cbs-devtools) — an open-source, all-in-one developer utility CLI built with Node.js and TypeScript.

Why I Built CBS DevTools

Whenever I was debugging an API or configuring a server, I needed quick answers without leaving my terminal. Opening web tools not only breaks developer flow, but pasting sensitive payload data or environment variables into third-party web converters poses real security risks.

CBS DevTools was engineered around three core principles:

• ⚡ Speed & Convenience: Run instant commands directly in your terminal without context switching.
• 🔒 Security & Privacy: 100% local execution — cryptographically secure random generation and offline JWT parsing without sending data anywhere.
• 🎨 Intuitive DX: Both interactive arrow-key terminal prompts for discovery AND direct subcommands for power users.

Designing the Interactive Terminal DX

One of my main design goals was to ensure you don't need to memorize dozens of CLI arguments to use the tool. If you launch CBS DevTools simply with:

cbs

It opens an interactive terminal interface powered by @clack/prompts. You can navigate between utility categories using your keyboard arrow keys and follow step-by-step prompts:

For experienced CLI users or automation scripts, every utility can also be triggered directly as a single subcommand.

Comprehensive Feature Toolkit

CBS DevTools brings together 7 major categories of developer utilities inside one unified package:

Direct Subcommands & Examples

Here are some of the direct subcommands you can run instantly in your terminal:

cbs ip

cbs local-ip

cbs dns google.com

cbs ping google.com

cbs uuid

cbs password

cbs qr "https://example.com"

cbs system

Under the Hood: Tech Stack

Building a reliable cross-platform CLI requires choosing tools that ensure type safety, clean input handling, and crisp output rendering:

Installation & Quickstart

You can install CBS DevTools globally via npm:

npm install -g cbs-devtools

Then launch the CLI anytime:

cbs

Or run commands on-demand without installing using npx:

npx cbs-devtools

Engineering Reflections & Lessons Learned

Building CBS DevTools gave me a fantastic opportunity to explore developer experience (DX) from the command-line perspective.

While most of my work focuses on full-stack web and mobile applications, engineering a CLI required thinking deeply about command taxonomy, terminal color palettes, spinner feedback during asynchronous tasks, robust error handling, and cross-platform terminal compatibility across Windows PowerShell, macOS zsh, and Linux bash.

It reinforced the principle that small everyday utilities become exponentially more valuable when organized inside a cohesive, well-designed developer experience.

What's Next

Here is what I'm planning for upcoming releases:

• ✓ Expanded string & text transformation utilities
• ✓ Enhanced cross-platform terminal compatibility
• ✓ Advanced file archival and multi-format compression
• ✓ Rich interactive terminal UI prompt controls
• ✓ Comprehensive documentation & API guides
• ✓ Automated unit & integration test suites
• ✓ Open-source community contribution workflows
