I am a software developer and the creator of Mermaid Live Editor — a free online tool used by thousands of developers to create flowcharts, sequence diagrams, ER diagrams, class diagrams, Gantt charts, and more, all using plain text Mermaid.js syntax.

I built Mermaid Live Editor after spending too much time switching between draw.io, Lucidchart, and whiteboard tools during architecture reviews. Text-based diagramming keeps diagrams close to the code, version-controllable, and shareable without file attachments. Mermaid Live Editor makes that workflow frictionless — no sign-up, no cloud storage required, instant real-time render.

My technical background spans full-stack web development, developer productivity tooling, and AI-assisted development. I work at Sambhav Tech AI and have been writing software professionally since 2015. I write the content on this site to make Mermaid.js accessible to developers who are adopting diagrams-as-code for the first time, as well as experienced Mermaid users looking for advanced patterns.

All content on this site — every tutorial, comparison, and code example — is written and reviewed by me personally. Every code block has been tested in the Mermaid Live Editor before publishing.

Everything published on mermaideditor.lol is written and reviewed by me personally. I do not publish AI-generated filler content. Every code example in every article has been tested in the live editor before publishing.

I use Mermaid.js daily in my own engineering work — architecture reviews, onboarding documentation, sprint planning, and system design sessions. The comparisons (Mermaid vs Draw.io, Mermaid vs PlantUML, etc.) are based on direct hands-on use, not vendor spec sheets.
