Frequently Asked Questions
Everything you need to know about DiagramFlow pricing
Can I try DiagramFlow for free?
Yes. The Free plan gives you 10 diagrams per month, 100 MB of storage, and access to all cloud icon libraries (AWS, GCP, Azure) and C4 model templates. No credit card required.
What happens when I hit the free plan limit?
Your existing diagrams stay accessible. You can view, share, and edit them anytime. To create new diagrams beyond the monthly limit, upgrade to Pro.
How does billing work?
Pro is billed monthly at $12/month, or annually at $120/year (saving you 17%). You can switch between monthly and annual billing at any time. Enterprise pricing is custom based on your team size and needs.
Can I get a refund?
Yes. We offer a 30-day money-back guarantee on all Pro subscriptions. If DiagramFlow doesn't work for your team, email us and we will refund you in full.
How do I cancel my subscription?
Log in to your account, go to Settings, and cancel anytime. Your diagrams remain accessible, and you keep Pro features until the end of your billing period.
What cloud providers do you support?
DiagramFlow includes built-in, always up-to-date icon libraries for AWS, Google Cloud, Azure, and other major cloud platforms. All icon libraries are available on every plan, including Free.
Do I need to know how to code?
The text syntax takes about 5 minutes to learn. You define services, connections, and cloud resources in simple, readable code. We also provide templates so you can start from a working example and customize from there.
How does DiagramFlow compare to Lucidchart or Draw.io?
Lucidchart and Draw.io are drag-and-drop tools. DiagramFlow generates diagrams from code, which means your architecture diagrams update in seconds instead of hours. Diagrams live in Git, version-controlled alongside your infrastructure code.
Can my team collaborate on diagrams?
Real-time collaboration is available on Pro and Enterprise plans. Multiple team members can edit the same diagram simultaneously, leave comments, and share via link.
