Auto Counter
Count up or down automatically at any speed. Every setting lives in the URL — paste a link and the counter starts where you left off.
What is an auto counter?
An auto counter is a counter that increments — or decrements — at a configurable rate without you tapping anything. You set the start, the target, and the speed; the page does the rest. Behind the scenes it uses a high-resolution timestamp, so the number is exact even when you tab away for a minute or an hour.
What's it good for?
- Video shorts and reels — drop a counter ticking up to a million as a B-roll element.
- Classroom and study — visualise "1 to 1000" or count seconds for a drill.
- Livestream overlays — donations, signups, view milestones racing to a goal.
- Demonstrations — population-style "events per second" widgets.
- Speedcounting challenges — count to a billion at 125 per millisecond.
URL parameters
Every setting lives in the URL so any configuration is a shareable link. Examples:
- /counters/auto-counter?from=0&to=1000000000&rate=125&unit=ms&start=1
- /counters/auto-counter?from=1000&to=0&rate=10&unit=s&start=1
- /counters/auto-counter?to=100&rate=1&unit=s&label=Pushups&suffix=%20reps&start=1
Supported keys: from, to, rate, unit (ms|s|min|hr), dir (up|down, auto-inferred from from→to), start (0|1 autostart), loop (0|1), label, prefix, suffix, decimals (0–3), format (commas|none).
