Task Haven by 32win

Task Haven helps you protect your attention when you need to get things done. Switch on focus mode and distracting pages won’t load you’ll see a gentle reminder instead. You control the list: add a host by typing it in or add the page you’re on with one click. If you prefer a stricter setup, turn on “only allow listed sites” so everything else is blocked during focus. A built-in timer lets you run sessions from a few minutes up to a couple of hours, and automatically turns focus off when time’s up. Everything runs locally in your browser. Task Haven doesn’t require an account, doesn’t track you, and never sends your data anywhere.
