Show HN: SaaSPopup – Real-Time Social Proof Popups for SaaS Conversions

Hey HN, I built SaaSPopup (https://www.saaspopup.com/), a lightweight tool to display real-time subscription notifications on websites—like “Someone in London just subscribed!”—to boost trust and conversions. It integrates with Stripe, LemonSqueezy, and RevenueCat, and I launched it on Product Hunt today.

The idea came from experimenting with social proof on my own projects. I noticed live activity (vs. static counters) creates urgency and credibility, especially for SaaS and e-commerce. SaaSPopup makes it plug-and-play:

- One-line script, live in ~5 minutes.

- Pulls verified purchases with location data.

- Customizable templates, colors, animations (no code).

- $8.99/month per site, no limits on notifications.

It’s a solo dev effort, built to stay simple and fast—minimal footprint on site performance. Early tests showed a ~25% conversion lift for some setups, though it varies by audience.

Curious what you think:

Useful for your projects? Any integrations or tweaks you’d want? How do you handle social proof now?

Thoughts welcome!
