Three questions to ask for each alternative: Does it share enough categories with OpenPhone API to be a real substitute? Is its engagement ratio above 0.25? Did it launch recently enough to reflect current technology? If the answer is yes to all three, it belongs on your shortlist.
Discussion threads divided by interest score. Above 0.30 is strong. Means people cared enough to write about it. Below 0.15 is a warning sign: lots of eyeballs, not much substance. We've found it's the single best predictor of whether a product has staying power.
No. Zero sponsorships, zero paid placements. Rankings come directly from community engagement data.
We pull new launch data regularly and rebuild the entire index. Historical scores are preserved. A product's launch-day numbers don't change retroactively, which keeps the rankings honest.
Because interest score measures initial attention, not quality. A 300-interest product with 0.50 engagement ratio has a small, obsessed audience. That's usually a better sign than 3,000 interest with 0.08 engagement, which screams 'great marketing, thin product.'
The index tracks launches automatically. If something's missing, it either launched below our engagement threshold or hasn't been indexed yet.
