Editorial interest 78/100 Selection signal · not a rating of the site

A browser-based workspace for turning Mermaid code into PNG, SVG, or JPEG diagrams, with theme and export controls.

Landing page captured for the 2026-09-29 issue.

For: People exporting Mermaid diagrams for documents and slides
Worth noticing: Its export walkthrough distinguishes the transparent canvas from node fills, which retain the selected theme’s colors.

Field notes

The workspace pairs a source editor with a live preview, syntax feedback, starter diagrams, and controls for themes and output formats. PNG exports can be adjusted from 1x to 4x resolution, with editable filename and padding; the walkthrough says large diagrams retain the selected resolution. Drafts are saved only if the user enables Remember my work, and the page provides an option to clear saved data from the device.
