AI agent builder statistics, September 2026

Miles FosterOwner and tester, RankDude

Every month I measure 25 AI agent builder sites with data from DataForSEO, Google Trends, Tranco and Ahrefs. They are the sites that rank on Google for "ai agent builder" plus the most-visited AI agent builder sites overall. In September 2026 they got about 1.9 million visits from Google, 27% fewer than a year ago.

Market demand

1Is the AI agent builder market growing in 2026?

Shrinking.

Over two years, visits went from 1.0M in October 2024 to a high of 2.7M in January 2026, fell to 1.6M in May 2026, and recovered to 1.9M in September 2026. Five sites take 81.4% of visits, so one ranking change at the top moves the whole line.

Miles explains

I only call a market growing when visits and name searches agree. Here visits are down and name searches are down, so they agree.

Monthly analysis

3What changed in the AI agent builder market in September 2026?

Fewer visits than a year ago, fewer people searching by name, and the next six months look flat.

The fastest growers over the year, MindStudio, Browserbase and Botpress, grew fastest, mostly from a smaller base. The losers, led by CustomGPT, lost most of their search visits (-90%).

Miles explains

Huge percentages like MindStudio’s +1953% usually mean one site won a big Google ranking from a small start. I watch whether it holds the next month.

Monthly forecast

4What happens next for AI agent builders?

I expect October 2026 to be about the same as September 2026, and the next six months to look flat.

The forecast carries the level of recent months forward, not the trend line, because that version missed least when tested on past months.

Miles explains

Voiceflow alone has 27% of all visits. That’s a big lead, but one Google update can close it fast.
