Turn customer trust into a growth channel
Scattered feedback and buried testimonials cost you trust. Stacklix brings everything together, so prospects buy with confidence and customers stay longer.
FeatureBoard is free to start · No credit card · Proof and Reply coming next
Customer context gets lost between tools.
Three disconnected moments quietly weaken trust across the customer journey.
Feedback is scattered
Requests disappear across tickets, calls, and inboxes—so teams build from noise instead of demand.
Customer testimonials stay hidden
The proof buyers need sits in private threads, making every new sale work harder than it should.
Conversations lose context
Disconnected replies make customers repeat themselves, wait longer, and quietly lose confidence.
Start with one job.
Add the next when you need it.
Each app is useful on its own. Together, they carry customer context from what people ask for to what convinces and retains them.

About the suite.
Product-level questions live on each product page. These answers explain how Stacklix works.
Is Stacklix one product or several?
Stacklix is a suite of focused products. FeatureBoard, Proof, and Reply share one account and design system, but each solves a distinct job.
Can I use only FeatureBoard?
Yes. FeatureBoard works independently, and you can stay on FeatureBoard without adopting another Stacklix product.
Do I have to buy a bundle?
No. Each product has its own plan. Start free and pay only when a product creates enough value for your team.
When will Proof and Reply launch?
They are currently planned products. Join the waitlist for launch updates; no availability date is promised yet.
Listen today. Grow the customer stack tomorrow.
