Lingo.dev

Lingo.dev (formerly Replexica) is an AI localization platform for software teams. Its hosted Localization Engine exposes a Bearer/X-API-Key REST API and SDK for translating text, objects, chat messages, HTML, and string arrays while preserving structure, brand voice, and glossaries. Open-source tooling - the CLI and the build-time React Compiler - sits on top of the same engine.
