Show HN: ZenTabTimer, an HTML timer where browser favicon is the timer

An HTML page where the favicon is a circle that drains over timer. Great for pomodoro work sessions while keeping the timer in view. Like a zen sand timer for your browser.

I found myself using the timer built into google search all the time to keep on track during a work session, but as soon as I had too many tabs, I'd end up clicking the tab all the time to see how much time was left. Plus, the countdown change movement would become visually distracting. Here, the circle "drains" without visible or distracting movement.

Vibe coding used to be a fun term for a low stakes thing made for fun, but these days it's a become a loaded term as real companies pressure their devs to vibe!

So, let's call this thing "Vibegentically Agenteered" to mean what vibe coding used to mean, a quickly made low stakes thing just for fun.
