A free, open-source Breathwork timer with a guided visual pacer. Pick a pattern, follow the breathing circle, and let go. No ads, no sign-up, no tracking. It runs entirely in your browser and works offline.
Live demo: https://cryptormac4.github.io/breathwork-timer/
| Pattern | Timing | Best for |
|---|---|---|
| Box breathing | 4-4-4-4 | Focus, steadying the nervous system |
| 4-7-8 | 4-7-8 | Winding down, sleep |
| Coherent breathing | 5-5 | Heart-rate variability, ~6 breaths/min |
| Calming | 4-6 | Gentle downshift, no breath-holding |
| Custom | Your timing | Set your own inhale / hold / exhale / hold |
Other touches: a soft 432 Hz chime on each phase (optional), mobile vibration cues (optional), a session timer with auto-stop, and a circle that expands on the inhale and settles on the exhale so you can follow it with your eyes closed-ish.
We are Liquid Breathwork, a Breathwork education company in Phoenix, Arizona. We teach a surrender-based, relaxation-focused style of Breathwork (no forced catharsis), and we kept wishing there were a clean, free pacer to point students toward. So we made one and open-sourced it.
If you want to go deeper, we run live classes across Arizona and Lake Tahoe and a Breathwork facilitator training for people who want to guide this work themselves.
Everything is vanilla HTML, CSS, and JavaScript with zero dependencies. Clone it, open index.html, and you are running. To embed it, drop the three files on any static host or iframe the live demo.
