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

Zero-Config SDK

No need to rewrite your SwiftUI `Text()` views. LangCat intercepts `Bundle.localizedString` safely at runtime.

Free

Over-The-Air Updates

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

Free

Multi-Environment

Draft localizations in a safe Sandbox environment on debug builds before promoting strings to Production via the dashboard.

Free

Cloudflare Edge Delivery

Localizations are compiled into static JSON manifests and distributed globally on Cloudflare KV for sub-100ms API fetching.

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

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.
