OpenCLI: Turn Anything into a Command-Line Tool

Ever find yourself wishing that a website, a local GUI app, or even a random binary had a clean, scriptable command-line interface? You’re not alone. The terminal is a developer’s home turf—it’s where we automate, chain tasks, and get things done fast. But not every tool is built with the CLI in mind.

That’s where OpenCLI comes in. It’s a clever project that acts as a universal adapter, letting you wrap almost any target—a website, an Electron app, or a local binary—into a standardized, consistent command-line interface. Think of it as giving a CLI makeover to tools that never had one.

What It Does

OpenCLI is a framework that allows you to define a command-line interface for targets that aren’t inherently command-line based. You write a simple configuration that describes the commands, arguments, and options you want, and OpenCLI handles the translation between your terminal input and the target application or service.

Essentially, it creates a bridge. For a website, it might orchestrate headless browser interactions. For a local binary with only a GUI, it could drive it programmatically. The result is a predictable CLI you can use in your scripts, your automation, or just to save yourself from repetitive clicking.

Why It’s Cool

The magic of OpenCLI is in its flexibility and its developer-centric approach. Instead of begging for a CLI feature or writing a one-off script you’ll never reuse, you can define a structured interface once. This is incredibly powerful for:

• Internal Tools: Wrap that legacy internal admin web portal with a CLI so your team can automate common tasks.
• Electron Apps: Many modern desktop apps are built on Electron. OpenCLI can provide a missing scripting API for them.
• Local Binaries: Give a CLI to a GUI-only binary tool, making it usable in CI/CD pipelines.
• Standardization: It encourages a consistent command structure (app verb --option) across all your wrapped tools, reducing cognitive load.

It’s a pragmatic solution to a very real problem: the world is full of useful software that forgot about the terminal.

How to Try It

The project is open source and lives on GitHub. The best way to understand it is to see the code and examples.

1. Head over to the repository: github.com/jackwener/opencli
2. Check out the README for an overview and the examples/ directory to see practical configurations.
3. The project is in Go, so you can clone it and build it locally to start experimenting with your own wrappers.

The repository is the documentation and the demo. Start by looking at how the example configurations are structured—it’s the quickest way to grasp how you’d adapt it for your own use case.

Final Thoughts

OpenCLI feels like one of those tools you didn’t know you needed until you see it. It won’t replace native CLIs, but it’s a fantastic stopgap and automation enabler for the countless tools that lack one. It’s especially useful for developers looking to streamline their workflow, automate tedious interactions, or bring consistency to a collection of disparate tools.

If you’ve ever wasted time manually clicking through a web interface for the hundredth time, this project might just be your next weekend experiment.
