Day 4 of building Languine:

📊 Analytics and feed
⚙️ Settings (Context, Brand Voice, etc.)
🔐 Account settings
📁 Project settings

It's amazing what you can build with tools like Nextjs, Shadcn, and Vercel in a couple of days!

It's 2025, open source it.

Thank you all for a great year, excited for what's to come! 🫶

Languine Translate your application with Languine CLI powered by AI.

Feel free to follow along over at @languine_ai and let us know if you are interested in automated translations for your application!

languine.ai

We'll deliver an open-source project in one sprint (7 days) using:

📊 Dashboard - @nextjs
☁️ Hosting - @vercel
🔗 API Framework - @honojs
🌐 ORM - @DrizzleORM
🔒 Auth @better_auth
🛠️ Backend (D1, KV, Queues, Analytics, AI) - @CloudflareDev
🎨 UI - @shadcn

While a CLI works perfectly fine, there are other things we need to translate dynamically using a service, fine-tune, analyze, and more. So, we needed a service and figured we could do this for a broader audience.

@languine_ai started because we needed translations for @middayai. We are fully self-funded and bootstrapping, so we needed a solution to fit our pockets and couldn't find one.

We started by releasing our CLI to implement translations and it got a lot of tractions and requests

Viktor and I will take a one-week sprint to make @languine_ai a SaaS, based on the needs of Midday:

🌐 Automatic translations (CLI/CI)
🔗 APIs
📊 Dashboard (Analytics, Fine-tune, Feedback loop, Settings, etc.)
💰 Free + Paid plans
🔓 100% open source

Add translations to react-email by just adding a language file:

🌐 Install `@languine/react-email`
📂 Add locales/en.json
✅ Done

Link ⬇️🧵

Support for extracting translation keys from source code coming to Languine:

- t("welcome.home")
- intl.formatMessage({ id: "welcome" })
- <FormattedMessage id="header.title" />
- __("another.key")

Saves a lot of time to automatically add missing keys!

Introducing `@languine/react-email` - a lightweight i18n library for React Email.

Quick setup:
✨ Install `@languine/react-email`
📁 Add locale folder (en.json, ...)
⚡ Import { setupI18n } from '@languine/react-email'

Works with `languine` CLI for auto translations.

And as a bonus, we now support both JS and TypeScript configs thanks to @fuma_nama 🖤

To start translating your @expo app in seconds, just run:
$ npx languine@latest init --preset expo

languine.ai

Then in your application, you can just use the i18n translation function 🎉
