Hey Product Hunt!
I'm excited to share the Free Online Diagram to Image Converter with this amazing community!
How this came to life: I created this tool using vibe coding - an innovative approach that let me rapidly prototype and build exactly what I envisioned. The process was incredibly smooth and allowed me to focus on the user experience rather than getting bogged down in complex coding.
What makes it special:
1. Completely free - no hidden costs or premium tiers
2. Instant conversion from Mermaid code to high-quality PNG/SVG
3. Privacy-first - everything stays in your browser
4. Works on any device without downloads
Perfect for: Developers documenting APIs, product managers creating workflows, students making study guides, or anyone who needs professional diagrams quickly.
The vibe coding approach enabled me to iterate quickly and build something that actually solves real problems. From Monaco editor integration to 5x resolution exports - everything was designed with user needs in mind.
Thanks for checking it out, Product Hunt! ❤️
