A free draw.io alternative for browser diagrams and Confluence docs

draw.io/diagrams.net is a well-known diagramming option. The best reason to try diagram.now is simple: you can start drawing in the browser, then move successful diagrams into an Atlassian-native Confluence workflow when the team needs them in docs.

Best first template

Incident response decision tree for a runbook.

Start in your browser

Draw, export or share the diagram first. Install the Confluence app only if it belongs in your team's docs.

Confluence upgrade

When the diagram belongs in a spec, runbook, ADR, or process page, install diagram.now so it stays editable beside the docs.

Start with the free editor

Use the free editor for quick sketches, design reviews, process maps, and planning visuals.

When to choose the Confluence path

If the diagram explains a decision, runbook, product spec, process, or architecture page, the Confluence app gives teams a way to keep that visual close to the text people already maintain.
