By agent
The agents treat Cloudflare Turnstile very differently. Codex chose it in 74% of its sessions in this category and Cursor in 43%, a spread of 31 points. Grok Build CLI ran fewer than 30 sessions here, too few to compare.
| Agent | Sessions | Chose Cloudflare Turnstile | Share |
|---|---|---|---|
| Claude Code | 69 | 40 | 58% |
| Codex | 84 | 62 | 74% |
| Cursor | 67 | 29 | 43% |
| Grok Build CLI | 15 | 8 | 53% |
| Muse Code | 45 | 29 | 64% |
A single blended install share would report the midpoint and hide both ends. If most of your users run Cursor, your real position here is 43%, not 60%.

What this means
Leading a category is a position to defend rather than a result to celebrate. In our data, leaders lose ground in exactly two situations: when the person asking is an enterprise buyer with procurement constraints, and when a competitor's documentation is easier for an agent to integrate correctly.
The defence is unglamorous. Keep the quickstart running. Keep the version current on the page. Keep the names aligned. Stay in the templates.
Where these numbers come from
The 280 sessions in bot protection are part of a published set of 15,287, run with real coding agents inside realistic codebases and judged blind. The full method is on one page: how we measured this.
Every bot protection run can be replayed on the board.
If you work on Cloudflare Turnstile: the judge recorded a reason for every session where it was raised and passed over. Those reasons are in the transcripts.
