From the experiment

i18next was chosen in 5% of 500 judged internationalization sessions, ranking sixth. It was also raised as a candidate in 157 further sessions without being chosen.

This page reports what happened when Claude Code, Codex, Cursor, Grok Build CLI and Muse Code had to solve a problem in internationalization inside a realistic codebase. Not what a chat assistant says about i18next. What an agent actually installed.

By agent

Claude Code, Codex, Cursor and Muse Code land within 9 points of each other on i18next, which is closer than most products in this experiment manage. Grok Build CLI ran fewer than 30 sessions here, too few to compare.

By who was asking

i18next does much better with one kind of buyer than another. It won 21% of sessions asked as vibe coder and 0% of those asked as senior engineer.

What this means

This is an integration problem, not a presence problem. Agents raised i18next in 157 sessions and chose it in 27, 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 500 sessions in internationalization are part of a published set of 15,051, run with real coding agents inside realistic codebases and judged blind. The full method is on one page: how we measured this.

Every internationalization run can be replayed on the board.

If you work on i18next: 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 i18next?

Yes. i18next was chosen in 27 of the 500 judged sessions in internationalization, a 5% install share, ranking sixth in its category.

Does Claude Code recommend i18next?

In 7 of the 113 sessions in internationalization run with Claude Code, which is 6%.

Do different coding agents treat i18next differently?

Not much. Claude Code, Codex, Cursor and Muse Code chose it at similar rates, between 1% and 10% of their runs.

How was this measured?

Real coding agents at pinned versions were run in sandboxes inside 92 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 i18next considered but not chosen?

It was raised as a candidate in 157 sessions without being chosen, and chosen in 27. That is a 15% conversion from considered to chosen.

Where this comes from

Armature ran 15,051 judged sessions with Claude Code, Codex, Cursor, Grok Build CLI and Muse Code inside 92 realistic codebases, and published every run. The numbers on this page come from that work.
