How the Directory Rank works
Every ranked list, alternatives page and comparison on this site runs on one public formula. No tool can pay to move up.
- AI depth: 30%
- Public rating, adjusted for sample size: 30%
- Review volume: 15%
- Current buzz: 15%
- Free access: 10%
Small review samples are pulled toward 3.9 stars with a weight of 20 reviews. Thin research records take a 15% penalty. Tools rated under 3 stars by five or more reviewers never make a best-of list.
The Directory Rank is not the Alpha Score. Hands-on testing is explained at FullStack Alpha: how we test.
