Know when your extensions break
before your users do.

ExtPulse monitors every installed extension in real time and fires an alert the instant one crashes, disables, or changes permissions. You see it first.

Extensions fail silently.
Your users are your error log.

Chrome and Firefox don't notify you when an extension crashes or gets force-disabled. You find out through a 1-star review, a lost sale, or a frantic support ticket from someone who can't figure out why your extension stopped working.

What Pro unlocks

Everything in Free, plus:

Check every 30 seconds

Free tier checks once a minute, locked. Pro lets you dial down to 30 seconds — fast enough to catch a crash before your next user lands. Or set it to 5 minutes for quiet monitoring.

0.5 min min 5 min max
📊

Full event history export

Export your complete event log as CSV or JSON. Every disable, crash, version change, and recovery — timestamped. Drop it into your own dashboard, pipe it to a log tool, or send it to a client.

Persistent badge + alerts

The toolbar badge doesn't clear after 5 minutes. It stays until you look — so if you step away for 6 hours you still see what happened. Set a threshold: all events, warnings only, or critical only.

Quiet hours & custom lists

Configure a quiet window so you're not paged at 3am. Monitor all extensions or a handpicked list of the ones that actually matter. Less noise, more signal.

Common questions

What does Pro unlock that Free doesn't? +

Two things: a custom check interval (down to 30 seconds instead of the locked 1-minute free tier) and event history export as CSV and JSON. Monitoring, alerts, quiet hours, badge, and custom extension lists are all in the free tier.

Does it send my data anywhere? +

No. ExtPulse runs entirely inside your browser. The only outbound call is a one-time license verification to Gumroad's API when you activate Pro. All extension data stays local in your browser storage.

Does it work on Firefox? +

Chrome is live now. Firefox is in active review — one Pro license covers both browsers, so you won't need to purchase again when it ships.

How do I activate my license? +

After purchase, Gumroad emails you a license key. Open the ExtPulse options page (Options → Pro License), paste the key, and click Activate. Takes 10 seconds. The interval slider and export buttons unlock immediately.

What's in "future Pro features"? +

Anything added to the Pro tier after your purchase is yours automatically — no upgrade fees, ever. Planned: webhook notifications, team license support, and a structured event dashboard.

What if I want a refund? +

30-day full refund, no questions asked. Email petrovest@gmail.com with your order number and it'll be processed within 48 hours.
