Code Line Counter
Paste source code to count total lines, source lines of code, comments, blanks and maintainability signals without uploading anything.

Your explanation appears here
Line counters treat strings and embedded templates conservatively, so use the result as a practical code-size signal.
Your plan appears after counting
Estimate the effect of removing blanks, trimming long lines and extracting repeated code.
Count code first
Total lines are every physical line in the pasted text. SLOC counts lines that contain executable or structural source code after blank and comment-only lines are separated.
No. The counter runs entirely in your browser with client-side JavaScript. It uses no API calls, no external fetches and no persistent storage.
Different languages use different comment syntax. The tool applies language-aware heuristics for line and block comments, but strings containing comment-like symbols can still affect simple line-based counters.
Results are local estimates for quick code review and planning. Line counts do not measure code quality by themselves. Combine LOC, comment ratio and long-line signals with tests, architecture review and team standards. VisionVix accepts no liability for engineering decisions based on this output.
