Frequently Asked Questions
Everything you need to know about the Free and Lifetime plans.
Can I use DiagramFlow for free?
Yes. The Free plan gives you 10 diagrams per month, 100 MB of storage, cloud icon libraries for AWS, Google Cloud, and Azure, C4 model support, real-time preview, and shareable links.
What do I get with Lifetime?
Lifetime is a one-time $19 purchase. It unlocks unlimited diagram creation, unlimited storage, simple customization options, and limited AI usage without a recurring subscription.
Why is Lifetime discounted?
Lifetime is an early phase one-time offer while advanced recurring workflows are still being built. The $19 offer is 80% below the $95 reference price.
Do both plans support AWS, Google Cloud, Azure, and C4 diagrams?
Yes. Both plans support DiagramFlow's cloud icon libraries and C4 model workflows, so you can generate architecture diagrams for AWS, Google Cloud, Azure, and structured C4 documentation.
Do I need to know how to code?
Not much. DiagramFlow uses simple, readable text syntax that takes only a few minutes to learn, and you can start from templates instead of writing everything from scratch.
