NoProcrast

A browser extension that limits time spent on distracting websites, modeled on Hacker News's noprocrast feature.

Each tracked site gets a configurable visit window (maxvisit minutes of wall-clock time from first visit). Once that window closes, the tab redirects to a block page and stays blocked for a cooldown period (minaway minutes). A manual override is available — it grants one fresh maxvisit window but does not disable the system; once that window closes, the site blocks again normally.

How it works

Time is measured using a wall-clock session window, not accumulated active-tab time:

• The first navigation to a tracked domain starts a session window and records the current time.
• Every subsequent navigation to that domain checks how much wall-clock time has elapsed since the window started.
• If less than maxvisit minutes have elapsed, access is allowed with no state change.
• If maxvisit minutes have elapsed but the minaway cooldown has not yet passed, the tab is redirected to the block page.
• Once the full maxvisit + minaway period has elapsed since the session started, the next visit automatically starts a fresh window.

The block page shows how many minutes remain in the cooldown. If you return to an open blocked tab after the cooldown has expired, the page detects this and redirects you back to the site automatically.

All timing is checked at navigation boundaries — no background polling, no content scripts.
