Let’s be honest with ourselves.
As developers, and especially in the AI space, our dopamine baseline is wrecked. Whether you are trying to wrap your head around the complex math behind a new architecture, read a dense ML research paper, or just write solid code, the urge to open a new tab is constant.
We tell ourselves: "I'll just check X/Twitter while this script runs or this model trains." Three hours later, the script finished 2 hours ago, and you are deep in a YouTube rabbit hole.
I was stuck in this exact loop. Balancing my CS degree with a frontend bootcamp, my deadlines were piling up. I tried every "website blocker" out there. But let’s be real—when your brain wants a distraction, it takes exactly two clicks to disable a Chrome extension. Those tools are useless when your willpower is depleted.
I didn't need a friendly productivity app. I needed a ruthless dictator for my OS.
So, I built a Windows desktop app in Python (using PyQt) to solve my own problem. I call it Focus Flow, and it doesn’t "remind" you to focus. It forces you to.
Here is what happens under the hood when you start a session:
It executes OS-level commands (ipconfig /release) to physically sever your internet connection. You go completely offline.
A background thread ruthlessly hunts and kills all browsers (Chrome, Edge, etc.) using psutil.
It modifies the Windows Registry to lock the Task Manager, so you can't force-quit the process.
You are left alone with your local PDFs, your IDE, and your thoughts. Total isolation.
Want to give up and get your API access/Wi-Fi back early? You can, but you have to use the "Emergency Exit" and manually type out a long, humiliating "walk of shame" paragraph admitting defeat: "I am breaking my commitment to deep work...". It's psychologically so annoying to type that you usually just close the window and get back to work.
I built this to save my own focus, but it actually worked so well that I’m giving away the core version completely for free right now.
If anyone here struggles with getting distracted during long coding sessions and needs the same brutal lockdown I needed, let me know in the comments and I’ll drop the link.
Has anyone else built extreme tools just to hack their own bad habits?
