# State Graph 
## use case

Stategraph is a state management and visualization system for Terraform and OpenTofu. It replaces the flat state file (and the whole-state lock that comes with it) with a dependency graph of your infrastructure, stored on a server you can query, lock at the resource level, and reason about.

You keep writing normal Terraform. Stategraph changes where your state lives and what you can do with it.
Why Stategraph

A typical Terraform setup keeps state as a single blob in S3. That has two costs:

    One lock per state. Any apply locks the entire state, so your team's changes serialize — even when they touch completely unrelated resources.
    No visibility. The state is an opaque JSON file. There is no good way to ask "what depends on this?", "what would this change affect?", or "what is this costing me?".

Un peu comme rougail pour ansible en somme:
Inventory provides a complete catalog of your Terraform-managed infrastructure. Browse resources, modules, and types. Query your data with SQL. Build dashboards and find resources that aren't managed by Terraform.
