Hello everyone! After over a year of building Dub.co , we're very excited to finally launch on Product Hunt 🚀 Back in 2022, I built Dub as a side project to easily share links on social platforms (X, LinkedIn, and iMessage) with beautiful Open Graph images to improve click-through rates. The product...
Congrats on launch! How does Dub.co help track link performance across different devices and locations? Could you share a real-world example of how the analytics feature benefits marketing teams effectively?
Great idea, we will check this out for our social posting!
The API's responsiveness is impressive—getting polished components with minimal latency enhances productivity. Pairing it with tools like Apidog has further optimized my development process.
@serafimcloud Amazing product! I am not much of a UI developer, but I was able to build pretty sleek product website for our product using @21st.dev & @Windsurf at a pretty quick time. Love to see you guys launch on Product Hunt. Good luck!

The ability to discover, share, and craft UI components with other design engineers has already saved me hou...
Dub.co leads on raw interest score. Dub.co leads on engagement ratio. Dub.co leads on both metrics. That doesn't happen often.
These products share 2 categories: GitHub, Open Source. Moderate overlap suggests they target related but distinct use cases.
Dub.co is also tagged in Analytics, Marketing, which 21st.dev isn't. That suggests Dub.co positions itself more broadly or targets an adjacent audience.
21st.dev has unique category tags in Design Tools, Developer Tools. Different positioning can mean a different buyer profile, even within the same space.
Dub.co launched Mar 2024. 21st.dev launched Jan 2025. Dub.co has had more time to iterate and build a user base. 21st.dev had the advantage of launching into a more defined market with clearer user expectations.
Dub.co has a 0.17 engagement ratio (average), based on 244 discussion threads across 1,466 interest points. Middle of the pack for Open Source. Enough discussion to suggest real usage, but not the kind of buzz that indicates a category-defining product.
21st.dev has a 0.11 engagement ratio (below average), based on 136 discussions across 1,233 interest points. The low ratio suggests a launch that got attention but didn't convert that attention into sustained interest.

How directly these products compete. Three or more shared categories means they're going after the same user. One shared category means they approach the space from different angles. Zero overlap and they probably shouldn't be compared.
Comparisons are generated automatically when two products have enough data overlap. If the pair you want isn't here, the products might be in different categories or too far apart in engagement.
Either the product didn't meet our engagement threshold, or it doesn't share enough category tags with the other product to generate a meaningful comparison. We'd rather show no comparison than a misleading one.
Each product's data reflects its launch period. The comparison shows both products' engagement metrics from when they launched. The build date at the bottom of the page shows when the index was last refreshed.
Not yet. Current comparisons use launch-period data only. Post-launch tracking is on our roadmap.
Generally, yes. Engagement ratio is hard to fake. A product can generate artificial interest, but sustained discussion threads require people who actually used the product and had something to say about it.
