Interactive, zoomable diagrams as Slack files
Most Slack diagram bots post a static image: too small to read, impossible to explore. Arialine posts every diagram as an interactive HTML file — open it on Slack desktop and you can pan, zoom, and inspect a big architecture diagram like a map. A PNG posts alongside it for mobile and previews.
Static images don't survive real architectures
- A 40-node system diagram compressed into one PNG is unreadable at message width.
- Zooming a raster image just gives you bigger blur.
- Sharing a link to an external viewer means logins, permissions, and one more tab.
- Screenshots detach from their source — nobody can regenerate or edit them.
How the interactive render works
HTML file, native to Slack
The diagram posts as a real Slack file. On desktop, open it and get smooth pan and zoom — no external site, no login, nothing leaves your workspace.
PNG fallback everywhere
A PNG posts with every version, so mobile users and message previews always show the diagram. On mobile, download the HTML file and open it in the browser for the interactive view.
Always the latest version
The board's root message always carries the current render; every superseded version keeps its own exact HTML + PNG on its thread reply, so history is fully browsable.
Frequently asked
Do interactive diagrams work on Slack mobile?+
Slack mobile shows the PNG. For the interactive HTML view, tap the file, download it, and open it in your phone's browser.
Does the HTML file phone home?+
No — it's a self-contained snapshot posted as a Slack file. Your diagram content stays inside Slack.
Can I export the diagram?+
Yes — .mmd source, PNG, or SVG, from the board's export controls. You can also place a rendered PNG onto any Slack canvas.
