Built an AI tool? List it free →
Two rankings, in the open.
- Best overall (default) asks “which tool is best at this job?” Quality 70%, ease 20%, value 10%. Pricey tools can win. Ties go to higher quality, then stronger benchmark results.
- Best value asks “what do I get per dollar?” It is 60% value and 40% quality, where value comes from cost per quality point: the lowest paid monthly price divided by the quality score, with a bonus for a usable free tier. Free and open-source tools score 5.
- Quality starts from our hands-on 1–5 score and moves with public benchmarks (LMArena, Artificial Analysis, SWE-bench) where the tool's own model is ranked; without a benchmark, user ratings (Product Hunt, App Store) nudge it. Ease moves with user ratings. Every source and date is listed on each tool's page. Full method →
- Sponsorship never affects rank. The ranking code doesn't read sponsor data, and sponsored placements are labeled and kept out of these lists.
