NoCodeComments

Strip source-code comments without damaging the code around them.

NoCodeComments is a browser-first, privacy-friendly code comment remover. Paste code or open a local file, choose a language or use auto-detection, and get a comment-free result you can copy or download. Processing happens in your browser; source code is not uploaded to a server.

Features

• Conservative lexical scanning for line and block comments.
• Protects comment-like text inside configured strings, template literals and regex literals.
• Preserves line breaks inside removed multiline comments.
• Explicit language profiles for dozens of language families, plus a conservative generic fallback.
• Language detection from common filenames and source-code patterns.
• Drag-and-drop and local file opening.
• Copy, swap, clear and download actions.
• Optional blank-line collapsing and long-line wrapping.
• Live character, line and byte statistics.
• Light and dark themes.
• Keyboard shortcuts: Ctrl+Enter process, Ctrl+Shift+S swap, Ctrl+D download, Ctrl+L clear.
• No account, backend, build step or external service required.

Try it

Open the NoCodeComments web app.

To run locally, clone the repository and serve the project directory with any static HTTP server:

git clone https://github.com/Aaqibhafeezkhan/NoCodeComments.git
cd NoCodeComments
python -m http.server 8000

Then open http://localhost:8000.

Development and tests

Requires Node.js 20 or newer.

npm test

The test suite uses Node's built-in test runner. There is no dependency installation or application build step.

How it works

The reusable transformation function is stripComments(code, language) in src/comment-stripper.js. Language-specific delimiters and protected-string behavior live in src/languages.js.

The scanner is lexical, not a full parser or AST transformer. It does not compile, execute or guarantee syntactic validity of transformed code. Language dialects and context-sensitive grammar can require more sophisticated parsing. Unknown languages use a best-effort generic profile; select the language explicitly when accuracy matters.

See Phase 0 parser baseline for the supported behavior and limitations. The original implementation remains available in legacy/.

Contributing

Contributions are welcome. Please read CONTRIBUTING.md, follow the issue templates and include focused regression tests for parser changes. The project roadmap tracks the ongoing parser, CLI, safety and release phases.

Security

Please do not publish security vulnerabilities in public issues. See SECURITY.md for private reporting guidance.
