Why It Matters
draw.io is what you reach for when you need a quick architecture diagram without a license. ERDs, integration flows, org strategy visuals, network diagrams — it handles them all. The VS Code extension means you can keep diagrams version-controlled alongside your code.
For architects, the biggest advantage is the price: free, forever. When you’re doing a quick design session or need to sketch something for a Slack thread, draw.io gets you there without opening a procurement conversation. The Salesforce shape libraries aren’t as polished as Lucidchart’s, but they exist.
Alternatives
- Lucidchart — more polished, better collaboration, but paid
- Miro — better for whiteboarding and workshops
- Canva — better for presentation-ready visuals
