Most focus tools are too easy to cheat. When the urge hits, you just toggle the extension off. SPB works deeper. It blocks distractions at the OS level using DNS, process termination, and folder locks. There is no browser trick to get around it. Built for developers, writers, and ADHD brains who need a digital wall that actually holds. It is free, private, and local. No accounts and no data tracking. Just a way to finally finish what you started.

I built this because I am my own worst enemy when it comes to distractions. I found myself constantly bypassing browser extensions or switching to incognito mode to waste time. Most focus apps are too easy to turn off when you actually need them. I wanted something that felt like a digital wall. This tool actually works at the system level so those tricks do not work. It is local, free, and keeps your data on your machine. No accounts or tracking are involved because I believe productivity tools should be private. If you have ever found yourself "cheating" on your own focus timers by disabling plugins, this was made for you. I would love to hear which features you think are missing for a deep work session.
