Tab Scheduler Light - Chrome Extension

Hey IH 👋

I just launched Tab Scheduler — a Chrome extension that automatically opens any URL (or a set of URLs) at a time you define. No subscriptions, no cloud accounts, no BS.

The problem

I kept forgetting to open certain tabs at the right moment — a daily standup link, a trading dashboard at market open, a reporting page at the start of every shift. Browser bookmarks don't help. Alarms on my phone felt dumb for a computer task. I wanted something that just works inside Chrome.

So I built it.

What it does

Three scheduling modes:

• Daily at a fixed time — set a time once, the tab opens every day. Great for recurring meetings, dashboards, news sites.

• Every N minutes — opens on an interval (e.g. every 30 minutes), starting from a time you pick. Useful for monitoring pages or refresh-heavy workflows.

• Once — pick an exact date & time, the tab opens once and marks itself done.

Multiple URLs per task — one task can open several tabs at once. Schedule your entire morning browser setup in a single entry.

Sound alerts — optional audio notification when a tab opens. Comes with a default beep, or you can upload your own audio file (mp3, wav, whatever).

Enable / disable tasks — toggle any task on or off without deleting it.

Run now — trigger any task instantly with one click, outside its schedule.

Everything runs locally in the extension's background service worker using Chrome's Alarms API. No server, no login, no data leaving your machine.

Pricing

$19.99 — lifetime license, one-time payment.

No subscription ever. Free future updates included.

14-day free trial to try everything before buying — no credit card required, just your email.

Payments are handled by ExtensionPay, so I never touch your card details.

The stack

• Pure Manifest V3 Chrome extension (no framework)

• Chrome Alarms API for reliable background scheduling

• chrome.storage.local for persistence

• ExtensionPay for payments and trial management

• Offscreen API for audio playback in the background

~600 lines of vanilla JS. Deliberately kept simple so it stays fast and maintainable.

Early numbers

Just launched. Zero marketing budget, posting here as my first real distribution attempt. Would love honest feedback — especially if you've tried something similar and ran into friction.

If you've built browser extensions before, I'd love to hear how you approached distribution. The Chrome Web Store feels like a black box for discoverability.

Happy to answer any questions 🙏
