Mermaid Live Editor is a web application for editing, previewing, and sharing Mermaid diagrams in real time.
The tool addresses the need to create and collaborate on flowcharts, sequence diagrams, and Gantt charts without installing software. It provides a browser-based editor with live preview, allowing users to save diagrams as SVG files and generate shareable links for both viewing and editing. The editor can be deployed with Docker, with configurable build arguments to point to custom rendering services, Kroki instances for additional diagram types, analytics platforms, and Mermaid Chart integration.
The project suits teams and individuals who want a lightweight, self-hostable diagramming solution. It works well for organizations that need to embed diagram editing into their workflows or provide internal diagramming tools. The Docker deployment model makes it suitable for those who prefer to run services on their own infrastructure rather than relying on a hosted service.
Development activity shows consistent engagement with the codebase. The project maintains an active pull request review process, with automated deployment to preview environments for testing before merge. Releases are automated upon merging to the main branch, indicating a streamlined release pipeline. The maintainers actively invite community contributions and maintain communication channels for coordination.
