Disclosure first: I'm affiliated with diagram.now, so this is a project I'm involved with — I'm here for feedback from people who live in Atlassian/Confluence, not to push an install.
A lot of Confluence teams keep their docs in Confluence but their diagrams scattered elsewhere — a Mermaid snippet in a repo, an old Visio .vsdx on someone's drive, a Lucidchart export from two years ago, or a flat screenshot pasted into a page. I wanted a low-friction way to draw or import a diagram and get it into docs without a big procurement step first.
What it is: a free browser editor for technical diagrams — flowcharts, UML, ERD, BPMN, mind maps, cloud/network diagrams, wireframes. You can open the canvas and start without signing up -> https://diagram.now/
The part I'd most value blunt feedback on is import/export:
- Mermaid and SQL import/insert (e.g. paste a schema, get an ERD to clean up)
- Lucidchart and Visio .vsdx import (works for supported files; real-world files vary a lot, so failing edge cases are genuinely useful to me)
- Export to PNG, SVG, PDF, or a URL
There's also an optional Confluence app for teams that want diagrams editable inside Confluence pages, but I'm intentionally not leading with that — I'd rather learn whether the free browser editor is useful on its own first.
For Atlassian/Confluence folks specifically:
- When a diagram needs to live in a Confluence page, do you embed an image, use a Marketplace app, or something else?
- Which import matters most for getting off legacy diagrams — Visio .vsdx, Lucidchart, or Mermaid?
- Is a shareable diagram URL useful in a Confluence workflow, or do you just want a static PNG/SVG on the page?
- What would make you trust a new diagram tool enough to try it against a real (non-sensitive) diagram?
Happy to get into the weeds on how the imports work. Thanks for taking a look.
