That... and I wasn't a fan of paying just to save and share diagrams on other sites.</p> <p>What it does:</p> <ul> <li>No login required to try it, just to save/collab/share.</li> <li>Live Mermaid editor (flowcharts, sequence, ER, Gantt, etc.)</li> <li>Shareable diagram links</li> <li>Save/manage diagrams in one place</li> </ul> <p>Link: <a href="https://everything-mermaid.com" rel="noopener noreferrer">https://everything-mermaid.com</a></p> <p>I’m not trying to sell anything — I genuinely want feedback from people who actually use Mermaid:</p> <ul> <li>What feels clunky?</li> <li>What’s missing?</li> <li>Would you trust this over Mermaid Live or local tooling?</li> </ul> <p>If this kind of tool would be useful for you, I’d love to know what would make it a “daily driver.”</p> <p>Thanks for taking a look 🙏</p> webdev programming diagram
