# App Builder Index

> Independent reviews and star ratings for AI app builders. Independent editorial publication. Ratings are stars out of 5 to one decimal, never a 0 to 100 index.

Methodology: weighted mean of ten axes (reliability 16, integrations 16, seo_geo 13, design 12, agent_perf 10, speed 9, value 9, scalability 7, api_mcp 5, code_ownership 3), summing to 100. Launch ratings were seeded by our own testing panel and are labelled Editor panel; community ratings accumulate on top. Full method: https://www.app-builder-index.com/how-we-review
