How to Make Any Codebase Multilingual Without Touching the Logic

When teams go global, code travels faster than comments.
Most repositories have comments written in a single language, which makes onboarding and collaboration harder for non-native developers.
I built a small VS Code extension that solves one very specific problem:
translate code comments only — safely, with preview, and without modifying code logic.
The Problem
Code logic is universal, comments are not
Translating entire files is risky
Existing i18n tools focus on apps, not developer experience
Developers don’t want refactors just to understand comments
The Idea
What if comments could be translated:
automatically
into any language
with a preview
and applied only when the developer approves
That’s the core idea behind Code Comment Translator.
How It Works
Select a block of code in VS Code
Run “Translate Code Comments (Preview)”
The extension:
detects comments only
sends just the comment text to Lingo.dev
keeps code untouched
A side-by-side preview opens
Apply or discard changes explicitly
Why Lingo.dev
Lingo.dev fits perfectly because:
it handles runtime translation cleanly
preserves structure and intent
integrates easily into Node-based tooling
This isn’t a wrapper — the value is in comment detection, safety, and workflow design.
Real Use Cases
Global open-source contributors
Distributed engineering teams
Learning unfamiliar codebases
Reviewing legacy projects
Conclusion
Internationalization isn’t just about apps.
It’s also about how developers understand code.
Sometimes, the smallest tooling improvement can remove the biggest friction.
