From the experiment

Do coding agents recommend Google Cloud Run?

Google Cloud Run was chosen in 4% of 287 judged serverless compute sessions, ranking fifth. Measured with Claude Code, Codex and Cursor.

Published September 3, 2026 Read as Markdown

Google Cloud Run was chosen in 4% of 287 judged serverless compute sessions, ranking fifth. It was also raised as a candidate in 55 further sessions without being chosen.

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

By agent

With 11 wins spread across three agents, the rates below are small numbers and a difference between them is not yet a finding. They are here because the direction is worth knowing, not because the gap is established.

By who was asking

Google Cloud Run performs similarly across the four kinds of buyer, from 0% to 8%. That is unusual: the category leader changed with the persona in 14 of the 18 categories we measured.

What this means

This is an integration problem, not a presence problem. Agents raised Google Cloud Run in 55 sessions and chose it in 11, so it reaches the shortlist and then loses. Something at the last step is costing the session, and in our data that is usually a quickstart that does not run when pasted, documentation describing an interface that changed, or a package name that does not match the product name.

That is the cheaper of the two problems to have. The reason is written down in each losing transcript.

Where these numbers come from

The 287 sessions in serverless compute 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 serverless compute run can be replayed on the board.

If you work on Google Cloud Run: 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 Google Cloud Run?

Yes. Google Cloud Run was chosen in 11 of the 287 judged sessions in serverless compute, a 4% install share, ranking fifth in its category.

Does Claude Code recommend Google Cloud Run?

In 6 of the 96 sessions in serverless compute run with Claude Code, which is 6%.

Do different coding agents treat Google Cloud Run differently?

Not much. The three agents chose it at similar rates, between 2% and 6% of their runs.

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 Google Cloud Run considered but not chosen?

It was raised as a candidate in 55 sessions without being chosen, and chosen in 11. That is a 17% 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.
