> i18next was chosen in 6% of 224 judged internationalization sessions, ranking sixth. It was also raised as a candidate in 104 further sessions without being chosen.

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

## The numbers

| | |
| --- | --- |
| Category | Internationalization |
| Sessions in the category | 224 |
| Sessions where i18next was chosen | 14 |
| Install share | 6% |
| Rank in category | 6 of 20 |
| Codebases it won in | 2 |
| Raised as a candidate, not chosen | 104 |
| Chosen when considered | 12% |
| Site | i18next.com |

## By agent

With 14 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.

| Agent | Sessions | Chose i18next | Share |
| --- | --- | --- | --- |
| Claude Code | 77 | 6 | 8% |
| Codex | 78 | 7 | 9% |
| Cursor | 69 | 1 | 1% |

## By who was asking

i18next does much better with one kind of buyer than another. It won 22% of sessions asked as vibe coder and 0% of those asked as senior engineer.

| Who is asking | Sessions | Chose i18next | Share |
| --- | --- | --- | --- |
| Vibe coder | 54 | 12 | 22% |
| Junior developer | 69 | 0 | 0% |
| Senior engineer | 47 | 0 | 0% |
| Enterprise team | 54 | 2 | 4% |

## What i18next was up against

The full ranking in internationalization, from the same sessions:

| # | Product | Runs won | Share |
| --- | --- | --- | --- |
| 1 | next-intl | 57 | 25% |
| 2 | Django translation framework | 45 | 20% |
| 3 | Symfony Translation | 18 | 8% |
| 4 | Paraglide JS | 18 | 8% |
| 5 | Rails I18n | 17 | 8% |
| 6 | i18next **(this page)** | 14 | 6% |
| 7 | Built in-house (no product adopted) | 12 | 5% |
| 8 | Vue I18n | 10 | 4% |

## What this means

This is an integration problem, not a presence problem. Agents raised i18next in 104 sessions and chose it in 14, 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 224 sessions in internationalization are part of a published set of 6,455, run with real coding agents inside realistic codebases and judged blind. The full method is on one page: [how we measured this](/library/how-we-measured-this).

Every internationalization run can be replayed on [the board](/leaderboards/internationalization).

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 14 of the 224 judged sessions in internationalization, a 6% install share, ranking sixth in its category.

### Does Claude Code recommend i18next?

In 6 of the 77 sessions in internationalization run with Claude Code, which is 8%.

### Do different coding agents treat i18next differently?

Not much. The three agents chose it at similar rates, between 1% and 9% of their runs.

### How was this measured?

Real coding agents at pinned versions were run in sandboxes inside 63 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 104 sessions without being chosen, and chosen in 14. That is a 12% conversion from considered to chosen.
