AI-native localization for React, Next.js, Vue, Nuxt, Angular & Svelte
Coding agents extract and sync copy as they ship. Your team reviews translations in one dashboard — locale files stay generated output.
Setup
Install your i18n library and connect i18.dev.
Get started for free — no credit card required.
One dashboard for every language
Agents extract strings and push copy. Your team reviews every translation in one place. Locale files stay generated output — never hand-edited.
01
Extract
Your coding agent scans the codebase and pulls hardcoded strings into translation keys.
02
Review
Your team approves every translation in one dashboard — with QA checks for tone and culture.
03
Ship
Run i18dev pull to sync confirmed locale files back into your repo and ship.
Why Developers Choose i18.dev
Five outcomes that matter — faster setup, cleaner extraction, shared review, predictable pricing, and QA before ship.
Faster setup
Intelligent prompt-based setup. No docs studying.
A few copy-paste prompts wire your i18n library and i18.dev — so your agent does the setup instead of you reading docs.
Saves days

Faster setup
A few prompts. No docs studying.
CLI extraction
Extract hardcoded strings. Sync keys. Ship without friction.
The CLI finds hardcoded strings, turns them into i18n keys, and syncs them to the dashboard — no missed strings, no broken UIs.
Saves ~2 weeks
The agent does the heavy lift. You stay in flow.
Collaborative dashboard
Developers, translators, and PMs in one place.
Everyone reviews and ships translations together in the dashboard — no more emailing JSON files around.
Saves countless hours
Devs, translators, and PMs — same table, same truth.
Predictable pricing
Cheap, predictive pricing. 20 members free.
Among the cheapest starter plans in the market — with up to 20 team members on free, and no per-seat tax.

Strings + tokens
No per-seat surprise bills
QA agents
Double-check every translation with built-in QA.
QA agents research each translated context and surface reports — so legal, cultural, and tone issues get caught before ship.
Safer locales
Every translation gets a careful once-over before it ships.
Cheapest starter. More strings.
Stored strings = source words × languages. Same base as everyone else. Translation cost = LLM tokens only. That is where we differ.
