Bubble6 million builders 2

Zoho Creator6M+ users 3

Thunkable5M users

Quick answer

Bubble is the largest low-code app builder, with 6 million builders, and Zoho Creator matches it with 6M+ users for business apps at US$8 a user a month. Thunkable (5M users) and FlutterFlow (3.3M people) lead for mobile apps. For portals and internal tools, Softr has 1M+ builders and Budibase is the leading open-source, self-hosted option.

How it's ranked: Users or builders each vendor says it has, as published on its own website (read November 2026). Bubble and Zoho Creator both claim 6 million; Bubble is placed first for its larger app-building community. Glide and Retool publish only business or team counts, not users, so they are ranked last by those numbers. Counts are each company's own claims and are measured differently, so treat them as a guide to scale, not an audit.
