A product that pulled 500 interest in 2022 faced a different competitive landscape than one pulling 500 in 2026. The bar rises every year as more products enter every category. Compare products within their year cohort, not across years.
Engagement ratios are more stable across time periods. A 0.40 engagement ratio meant the same thing in 2022 as it does now: people cared enough to discuss it at length.
Primary target audience at launch. Some products serve both. We classify based on who the product was positioned for, not who ended up using it.
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.
