"I built TestStack to solve the most frustrating problem I faced as a freelancer, social proof.

When I started freelancing, I thought doing great work would be enough.

But time after time, after delivering a project, I’d get a “thank you” and… that was it. No testimonial. No public feedback. Just a ghost town when I’d ask.

The problem wasn’t that clients didn’t like the work, they were happy.
It’s just that collecting feedback felt like I was asking for too much.
Even when I got something, it was buried in Slack threads or email chains.

So I built TestStack.

It’s a lightweight, no-login tool that takes client messages, chats, emails and turns them into clean, polished testimonial cards in seconds.

No design skills needed. Just paste and go.

I'm using it now to showcase my work with actual proof, and it’s already led to stronger replies, more trust, and more conversions.

Try it here: https://teststacklandingpage.netlify.app/

It’s free. No signups. Just solves a real pain I was tired of dealing with.

If you're a freelancer or solo builder, I'd love to know:

👉 What do you currently use for testimonials?
👉 Do you even bother collecting them?
👉 Would you ever automate this part of your workflow?

Let’s talk.
