  • I Built a Privacy-First, Syntax-Aware Diff Tool because "Text Compare" Wasn't Enough
    I built Diff Guru to solve the privacy issue by making it 100% client-side with unlimited merge capabilities. But today, I’m excited to announce a massive update: Language-Specific Syntax Highlighting. - Source: dev.to / 11 months ago
