We're working on it. Right now, the index captures launch data and community metrics. Direct product links are coming in a future update.
April 2021. Five years of launches, covering the entire AI boom, the no-code wave, and multiple cycles of every major category.
Not yet. The current index captures launch-period engagement. We're evaluating ways to track post-launch traction, but it's a different data problem and we want to get it right.
Check the comparisons section. We auto-generate side-by-side pages for products that share categories and have similar traction levels. If the pair you want isn't there, the products might be too far apart in engagement to make a meaningful comparison.
By community interest score. Higher score means more people engaged with the product at launch. We show engagement ratio as a secondary metric because it separates one-day hype from products that generated real conversation.
