Stripe Payment Links Replacement

https://usecaart.com
2•kdavidson•9mo ago

kdavidson•9mo ago
Hey HN,

Over the past few years, I’ve sold a bunch of digital products and SaaS, and one thing I kept running into was how barebones Stripe’s hosted payment links are. They work—but they’re not optimized for conversion.

So I built Caart (https://usecaart.com): a tiny layer on top of your Stripe payment links that adds things like:

- Countdown timers (urgency)

- Testimonials (social proof)

- Purchaser counts (FOMO)

- Abandoned cart recovery (via email)

- Support for one-time & subscription payments

- …and more coming soon

The goal is to give you all the conversion-boosting stuff without needing to install a full checkout flow, mess with APIs, or hire a dev.

It’s super simple: connect your Stripe account, customize your Caart page, and go live.

We just finished building it and I’ve been using it for my own sales pages and saw a clear lift in conversion, so I figured others might find it useful too.

Would love any feedback, especially on what you’d want it to do next, or what feels overkill.

We need more early users so we launched with ridiculously cheap pricing just so we can shorten the feedback loop while we learn what works and what doesn't. So for the time being it's $95 for lifetime access. We just want to see if people like it or need it.

Happy to answer anything!
