Cloud architecture diagrams
Services drawn with official provider icons, nested inside cloud, region, VPC, availability zone and subnet boxes worked out from your references.
Terraform → architecture diagram
See what your Terraform actually builds.
TF Diagrams turns .tf files into interactive cloud architecture diagrams and dependency graphs. Everything runs in your browser; your code never leaves your machine.

Product tour
See it in action
Real screenshots from the app, using the sample projects it ships with. No mock-ups.
Everything in one view
Built for reviewing infrastructure, onboarding to a new codebase and explaining a stack to your team.
Dependency graph
Every resource, data source, module, variable, local, output and provider, laid out from inputs to outputs.
Read the source
Open any file with syntax highlighting. A node’s file and line jump straight to the block that defines it.
Click to trace
Select a node to highlight everything it depends on and everything that uses it, with its source and clickable references.
Filter and group
Narrow the graph by block kind and group it by file to focus on the part you care about.
AWS, Google Cloud and Azure
One engine for all three providers, with the details each one does differently handled separately.
How it works
- 1
Load your Terraform
Drop a folder, open files or paste code.
- 2
Read the diagram
Switch between the cloud diagram and the dependency graph, filter and group.
- 3
Export
Save the graph as a PNG for docs, pull requests or slides.
Frequently asked questions
Is my Terraform code uploaded anywhere?
No. Files are read and parsed by your browser, and the diagram is drawn on your device. Nothing is sent to a TF Diagrams server.
Is it free?
Yes. There’s no sign-up, no paid tier and no usage limit. If it helps you, you can buy me a coffee.
Which cloud providers are supported?
AWS, Google Cloud and Azure. AWS and Google Cloud services use their official icons; Azure services are drawn as labelled tiles.
Does it run terraform plan or need cloud credentials?
No. It reads your .tf files directly, so it needs no Terraform install, state file or credentials.
Why is something missing from my diagram?
Expressions aren’t evaluated, so count and for_each aren’t expanded and module internals aren’t followed. Supporting resources such as security groups and route tables are left out of the cloud diagram on purpose; they still appear in the dependency graph.
Private by design
Parsing and layout happen entirely client-side. Your files are read by your browser and never sent to a server.
