Better I18N vs Locize
Locize is the managed translation backend built by the i18next team, in production for a decade. Better I18N is built for teams who want localization to live inside the codebase and be operated by AI agents. Both are real choices — this page is about which one fits which team.
Two different bets
What Better I18N optimises for
Not depth of translator tooling — Locize is ahead there and we say so below. Ours is a bet that localization belongs in the codebase and in the agent loop.
Localization that lives in the repo
The CLI scans your source for hardcoded strings, generates TypeScript types from your keys, and the GitHub App opens a pull request for translation changes. Copy gets reviewed the way code gets reviewed.
Agents as first-class operators
Two MCP servers — 17 translation tools and 11 content tools, hosted or local — with duplicate detection and phantom-key cleanup, so an agent write cannot quietly corrupt your catalog.
One price, every project
Pro is a flat $20 a month across up to 10 projects. No per-project plan to size, no per-seat line, and no upgrade forced by one missing feature.
Side by side
Where the two platforms actually differ
Every Locize value below comes from their own pricing page, docs, or their published comparison of the two products, read on 1 August 2026. Anything we could not verify is left blank.
| Besonderheit | Better I18N | Locize |
|---|---|---|
| Pricing model | Flat $20/mo Pro covering up to 10 projects, with a free tier below it and Enterprise above. | Free plan, then fixed plans from $7 to $199/mo priced per project by words and languages, or a usage-based plan from $5/mo with no hard limits. |
| i18next relationship | Our Expo SDK is built on i18next, but there is no dedicated i18next backend plugin. | Built and maintained by the i18next team, with a dedicated i18next backend plugin. Subscriptions fund i18next development. |
| Agent access (MCP) | Two servers: 17 translation tools and 11 content tools, hosted or local, with duplicate and phantom-key guards on agent writes. | One server with 26 tools, OAuth 2.0 read / write / manage / admin scopes, listed in the official MCP registry. |
| AI translation | Built-in AI with glossary support and dashboard review before anything publishes. | Built-in AI plus bring-your-own key (OpenAI, Gemini, Mistral), fed by translation memory, glossary and styleguide, with AI-judged quality scores. |
| File formats | JSON catalogs in the platform. Our free browser converter handles PO, XLIFF, ARB, YAML, CSV, Android XML, iOS .strings and Java .properties. | JSON, XLIFF, PO, Android XML, iOS .strings, resx, YAML, CSV and XLSX, handled inside the platform. |
| Git workflow | GitHub App opens pull requests for translation changes, so copy lands through review. | |
| CLI and SDKs | scan, sync, check, doctor and translate commands, with --json on every command. MIT-licensed SDKs for Next.js, Vite, Remix, Expo, Flutter and Swift. | CLI and API, plus the i18next ecosystem plugins. |
| Type safety | The CLI generates TypeScript types from your keys and content models. | |
| Translator tooling | In-context editor, screenshot context, review workflow and fine-grained per-user permissions. | |
| Translation memory | Translation memory and styleguide, feeding both human translators and AI. | |
| Release control | Publish to the edge CDN; changes reach production in about 60 seconds. | Versioned publishing, git-style branches and per-tenant overrides, so output can be gated before production. |
| CDN delivery | Included on every plan. Edge-cached, and the CDN always answers 200 — a stale copy rather than an error. | Included on every plan with a free monthly download allowance, split into standard and pro download tiers. |
| Data residency | EU, on AWS Ireland, with a modification history of who changed what. | |
| Seat pricing | None. Team size does not change the bill. | None. Users are a plan limit, not a per-seat charge. |
A blank cell means not available or not published — never worse. Locize's own comparison page lists several gaps on our side; we have not disputed them here, because they are accurate.
Pricing
Two shapes of simple
Neither side charges per seat, and at small scale both are cheap. The difference is what the meter counts.
How Locize prices
Fixed plans are per project and sized by two numbers at once: words and target languages. Words are counted as source words multiplied by languages, so adding a language multiplies the count rather than adding to it. Above the fixed plans sits a usage-based plan with no language, user or namespace limits.
3,000 source words × 5 languages = 15,000 words
Locize's own worked example for their $7/mo Starter plan (locize.com/pricing, read 1 August 2026).
What our flat plan covers
One bill for up to 10 projects
$20 a month, account-wide. If you run several small apps you are not sizing a plan per project.
Edge CDN delivery
No download tier to watch and no build step. The CDN always answers 200, serving a stale copy rather than an error.
Both MCP servers
Translations and content, hosted or local, with no separate agent seat or add-on.
A free tier that ships
Enough to put a real multilingual app in production before you decide anything.
An honest boundary
Where Locize is the better choice
We would rather you pick the right tool than pick ours. If any of these describes your team, Locize fits better — and we would say the same on a call.
You are deep in i18next
Locize is the managed backend built by the people who maintain i18next, with a dedicated backend plugin. If your app is already an i18next app and you want the shortest path plus a subscription that funds the library, that is a good reason on its own.
Your strings are not in JSON
Android XML, iOS .strings, resx, XLIFF or PO as the working format inside the platform is Locize territory. We store JSON catalogs; our converter can move files between nine formats, but the platform itself speaks JSON.
Translators are part of your team
In-context editing, screenshot context, translation memory and a reviewer role with scoped permissions are what a professional translation workflow runs on. Locize has all four today. We do not.
You need EU data residency
Locize runs in AWS Ireland and publishes a modification history. If a procurement review requires a stated EU region, that is a hard requirement and it decides the question.
Migration
Moving a Locize project across
Both platforms store namespaced JSON per locale, so the file shape barely changes. Most of the work is repointing the SDK.
Export your namespaces
Download the per-locale JSON for each namespace from Locize. Keep the namespace names — our CDN uses the same one-file-per-namespace layout, so they carry over as-is.
Push the keys
Point the CLI at the exported folder and sync. Existing translations come across as-is; nothing is re-translated unless you ask for it.
Swap the backend
Replace the i18next backend plugin with our SDK for your framework, or keep i18next and point it at our CDN URL. Locale codes are lowercased on our side.
Verify before you cancel
Run the CLI health check to catch missing keys and hardcoded strings, ship to staging, and keep the Locize project until the new path has served real traffic.
If your project relies on translation memory, screenshots or a reviewer workflow, migrating means giving those up. Read the section above before you start.
Questions
Better I18N vs Locize, answered
The questions teams actually ask when they have both tabs open.
Try it on a real project
See if Better fits your workflow
Start free, connect the CLI, and publish through the CDN. If it turns out Locize is the better fit for your team, we would rather you find that out in an afternoon than after a migration.
