LocEngine started from a simple observation: developers spend countless hours manually extracting strings and rebuilding i18n structures for their projects. What should take minutes often takes days or weeks.

In early 2023, while working on a multilingual application, our founder realized that the existing tools were either too complex, too expensive, or simply didn't work with legacy codebases. The idea for LocEngine was born: a tool that could automatically detect translatable content, generate proper i18n keys, and inject translations safely — even into projects without existing localization infrastructure.

What began as a personal script quickly evolved into something bigger. As more developers tested the early versions, the feedback was clear: this tool needed to exist. The prototype grew into a full-fledged application, adding support for more languages, more frameworks, and more complex use cases.

By late 2024, LocEngine had already processed over 500,000 strings in beta testing. Developers from small startups to large enterprises were using it to localize everything from simple mobile apps to complex enterprise systems with millions of lines of code.

Today, LocEngine supports 190+ file formats and frameworks, with a powerful scanning engine that combines regex, AST parsing, and fallback detection. We've built a tool that works for both modern i18n-ready projects and legacy codebases that never considered internationalization.
