Pinchtab: A Minimalist Orchestrator for Your Headless Browser Fleet

If you've ever needed to run multiple headless browser instances for scraping, testing, or automation, you know the pain. Spinning them up, managing their lifecycle, and tearing them down can quickly turn into a messy script. What if you had a simple, dedicated tool just for that job?

Enter Pinchtab. It’s a minimalist orchestrator designed to manage a fleet of headless browser instances. Think of it as a tiny, focused conductor for your browser-based tasks, keeping everything running smoothly without the overhead of a full-blown framework.

What It Does

Pinchtab provides a straightforward way to launch, manage, and connect to multiple headless browser instances (like Chrome or Chromium) from a central point. You tell it how many instances you want, and it handles the rest, giving you the connection details for each one. It’s essentially a lightweight process manager tailored specifically for browsers.

Why It's Cool

The beauty of Pinchtab is in its simplicity and singular focus. It doesn’t try to be a testing framework or a scraping library. It solves one problem well: orchestration.

• Fleet Management Made Simple: Need 10 browser instances for parallel processing? Pinchtab manages the ports, process IDs, and WebSocket endpoints, so you don't have to.
• Minimalist & Decoupled: Because it’s just an orchestrator, you can use it with any tool or library that can connect to a browser via DevTools Protocol. It plays nicely with Puppeteer, Playwright, or your own custom scripts.
• Developer-Friendly API: It offers a clean programmatic API and a CLI, making it easy to integrate into your existing workflows and automation pipelines.
• Perfect for Scalable Tasks: It shines in use cases like large-scale data extraction, load testing with real browsers, or running suites of visual regression tests in parallel.

How to Try It

Getting started is straightforward. Pinchtab is a Node.js package.

First, install it:

npm install pinchtab

Then, you can use it in your code. Here’s a quick example of launching a fleet:

const { Pinchtab } = require('pinchtab');

const orchestrator = new Pinchtab();
// Launch 3 headless Chrome instances
const fleet = await orchestrator.launch(3);

// fleet contains the connection info (like WS endpoints) for each instance
console.log(fleet);

// Later, gracefully shutdown the entire fleet
await orchestrator.destroy();

Final Thoughts

Pinchtab fills a neat niche. In a world of complex, all-encompassing tools, it’s refreshing to see a utility that does one specific job with minimal fuss. If you’re building something that requires a pool of browser instances, writing your own management glue code is a chore you probably don’t need. Pinchtab looks like a solid, no-nonsense solution to offload that responsibility.

It’s the kind of tool you might not need every day, but when you do, you’ll be glad it exists.
