# Vector databases: GitHub trend and outlook to 2032

On TutorHero's Everything Index (September 2026), Vector databases is cooling on GitHub: 0.63 of every 10,000 new public repos carried it over the last three months, about 578 new repos a month, 1.68x its share a year earlier. TutorHero's 12-month forecast (damped growth, beat a flat guess on past GitHub lines) says edging up (+18%). By the end of 2032, past GitHub lines in the same state ended between 0.28x and 4.8x of where they started, median 0.82x: a base rate, not a prediction of this line. In the 4 weeks to 2026-10-18, 494 new repos carried it, -26% against the typical tag. On Hacker News, about 2 stories a month carry it in the title (-15% share of HN in a year). Its Wikipedia article gets about 7.0k views a month by people (-24% share in a year). Compared with the typical trend it is talked about more than built. It sits in the RAG and memory megatrend. Not investment advice.
