Lately I’ve been spending more time documenting systems and infrastructure. That usually means creating diagrams — things like architecture charts, cloud architecture diagrams, or simple flowcharts to explain how services interact.

For a long time I used draw_io. It’s great for quickly creating diagrams, but collaboration can get messy when teams start sharing files.

Recently I found a tool called DiagramDeck (https://diagramdeck.com) and it’s been a nice alternative.

It’s a browser-based architecture diagram tool built around the draw_io ecosystem. You can create diagrams directly in the browser and collaborate with your team without installing anything.

It works well for things like:

• cloud architecture diagrams
• AWS architecture diagrams
• network diagrams
• UML diagrams
• process flow charts

Basically all types of diagrams teams need when documenting systems.

If you’re looking for an alternative for Lucidchart or a simple collaborative diagramming tool, it’s worth checking out.
