From the experiment

Do coding agents recommend Vercel?

Vercel is the most chosen hosting platform, taking 41% of 270 judged deployment sessions. Measured with Claude Code, Codex and Cursor.

Published September 3, 2026 Read as Markdown

Vercel is the most chosen hosting platform, taking 41% of 270 judged deployment sessions. It was also raised as a candidate in 132 further sessions without being chosen.

This page reports what happened when Claude Code, Codex and Cursor had to solve a problem in deployment inside a realistic codebase. Not what a chat assistant says about Vercel. What an agent actually installed.

By agent

The three agents treat Vercel very differently. Cursor chose it in 48% of its sessions in this category and Codex in 32%, a spread of 16 points.

A single blended install share would report the midpoint and hide both ends. If most of your users run Codex, your real position here is 32%, not 41%.

By who was asking

Vercel performs similarly across the four kinds of buyer, from 40% to 43%. That is unusual: the category leader changed with the persona in 14 of the 18 categories we measured.

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 270 sessions in deployment are part of a published set of 5,292, run with real coding agents inside realistic codebases and judged blind. The full method is on one page: how we measured this.

Every deployment run can be replayed on the board.

If you work on Vercel: the judge recorded a reason for every session where it was raised and passed over. Those reasons are in the transcripts.

Common questions

Do coding agents recommend Vercel?

Yes. Vercel was chosen in 112 of the 270 judged sessions in deployment, a 41% install share, ranking first in its category.

Does Claude Code recommend Vercel?

In 40 of the 90 sessions in deployment run with Claude Code, which is 44%.

Do different coding agents treat Vercel differently?

Yes, and by a wide margin. Cursor chose it in 48% of its runs and Codex in 32%.

How was this measured?

Real coding agents at pinned versions were run in sandboxes inside 51 realistic codebases and asked to solve real tasks. A simulated project owner approved or questioned each recommendation before any code was written, and a judge from a model family that builds none of the agents read every session blind.

How often is Vercel considered but not chosen?

It was raised as a candidate in 132 sessions without being chosen, and chosen in 112. That is a 46% conversion from considered to chosen.

Where this comes from

Armature ran 5,292 judged sessions with Claude Code, Codex and Cursor inside 51 realistic codebases, and published every run. The numbers on this page come from that work.
