Question 1

Which languages are supported?

Accepted Answer

JavaScript, TypeScript, CSS, SCSS, HTML, XML, Python, Ruby, Shell, Java, C, C++, C#, Go, Rust, PHP, SQL and Lua. Each language has its specific comment delimiters: // and /* */ for C-family, # for Python/Ruby/Shell, -- for SQL/Lua/Haskell,  for HTML/XML.

Question 2

Will it break my string literals?

Accepted Answer

No. The tool uses a state machine that tracks whether it is inside a string ('...'), template literal (`...`), or regex literal (/.../). Comment-like sequences inside strings are preserved exactly. This is critical for JavaScript regexes like /\/\//g which contain //.

Question 3

Can I keep documentation comments?

Accepted Answer

Yes. Tick 'Keep doc comments' to preserve JSDoc /** ... */, Python docstrings """ ... """ (when in triple-quote form), and SQL block headers. Use this when you want to minify code but keep API documentation intact.

Question 4

Is it safe to use on production code?

Accepted Answer

The tool runs entirely in your browser, so no code is uploaded. However, always review the diff before committing — a few rare edge cases (nested template literals, regexes with quotes) may need manual adjustment.
