Show HN: Free white noise mixer I built to help me sleep

Hey HN, I've been having trouble sleeping lately. Tried various white noise apps but most are either paid or cluttered with ads. So I built my own. https://whitenoiseforsleeping.rest https://whitenoiseforsleeping.rest Features: - Mix 6 nature sounds (rain, thunder, fire, wind, stream, birds) - 7 ambient scene backgrounds - Sleep timer with fade-out - Settings auto-saved to localStorage - No signup, no ads, no tracking Tech stack: React + Vite, hosted on Cloudflare Pages. The rain + fire combo works surprisingly well for me - usually fall asleep within 20 minutes now. Would love to hear your feedback or suggestions for improvement.
