Do coding agents recommend Apache Kafka?
Apache Kafka is the most chosen message queue, taking 14% of 288 judged message queues sessions. Measured with Claude Code, Codex and Cursor.
Apache Kafka is the most chosen message queue, taking 14% of 288 judged message queues sessions. It was also raised as a candidate in 136 further sessions without being chosen.
This page reports what happened when Claude Code, Codex and Cursor had to solve a problem in message queues inside a realistic codebase. Not what a chat assistant says about Apache Kafka. What an agent actually installed.

By who was asking
Apache Kafka does much better with one kind of buyer than another. It won 22% of sessions asked as enterprise team and 0% of those asked as senior engineer.

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 288 sessions in message queues are part of a published set of 7,852, run with real coding agents inside realistic codebases and judged blind. The full method is on one page: how we measured this.
Every message queues run can be replayed on the board.
If you work on Apache Kafka: 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 Apache Kafka?
Yes. Apache Kafka was chosen in 39 of the 288 judged sessions in message queues, a 14% install share, ranking first in its category.
Does Claude Code recommend Apache Kafka?
In 15 of the 96 sessions in message queues run with Claude Code, which is 16%.
Do different coding agents treat Apache Kafka differently?
Not much. The three agents chose it at similar rates, between 11% and 16% of their runs.
How was this measured?
Real coding agents at pinned versions were run in sandboxes inside 90 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 Apache Kafka considered but not chosen?
It was raised as a candidate in 136 sessions without being chosen, and chosen in 39. That is a 22% conversion from considered to chosen.
Where this comes from
Armature ran 7,852 judged sessions with Claude Code, Codex and Cursor inside 90 realistic codebases, and published every run. The numbers on this page come from that work.
