Everything you need to scale globally

We built the infrastructure so you can focus on building your app. From AI-driven context localization to sub-100ms global edge delivery.

Free

UIKit & SwiftUI Native

Zero-config for UIKit via runtime Bundle swizzling. For SwiftUI, use simple drop-in `LCText` components to handle dynamic OTA updates effortlessly.

Free

Over-The-Air Updates

Fix typos instantly. Push new localization files dynamically directly to your users' devices bypassing App Store review.

Free

3-Tier Fallback Architecture

Never show a blank string. The SDK uses lightning-fast Memory cache, persistent Disk syncing, and hardcoded `Localizable.strings` fallback.

Coming Soon

Version Management

Manage translation strings seamlessly on a per-version basis. Release targeted OTA localizations for v2.0 without ever breaking your legacy app users.

Coming Soon

LangCat Edge Delivery

Localizations are compiled into static JSON manifests and distributed globally on LangCat Edge Network for sub-100ms API fetching.

Coming Soon

AI-Powered Localization

Sync your .xcstrings file from the CLI, and our GPT-4o worker automatically localizes your keys utilizing your source code comments as context.
