Andreessen Horowitz's ranking of the top web and mobile consumer AI products by monthly traffic, the seventh edition of the series. a16z is a venture firm that invests in some of the companies it covers.
The methodology page for the TIOBE Programming Community Index, a monthly measure of programming language popularity calculated from search engine result counts for queries like "+<language> programming." The page explains which search engines qualify, which languages are included, and how ratings are calculated. The current index is free; long-term historical data is sold.
Why I recommend it: TIOBE measures search chatter, not code quality or job postings — read it as a popularity signal, not a skills roadmap. Pair it with job board data before advising anyone on which language to learn.
