AI GCP architecture diagram generator.
From the Terraform in your repository, with no project access and nothing uploaded.
Sources it reads
Terraform with the google provider, Deployment Manager configurations, and Kubernetes manifests for GKE workloads. Terraform is the common case and reads well, since the reference structure gives reliable edges without inference.
How Lucid Train draws one
Describe what you want, or point it at a repository. The agent emits a semantic graph of nodes and edges with no coordinates, and the ELK layout engine computes positions and orthogonal routing. That separation is the reason the output cannot come back with boxes overlapping or arrows crossing through cards, which is the characteristic failure when a language model is asked to place things on a canvas itself. It also means editing is editing the graph: change a component and the layout re-solves rather than drifting out of alignment.
Cloud Run and Functions as application components
GCP systems are frequently a set of Cloud Run services connected by Pub/Sub, which is a shape that draws cleanly: services in the application tier, Pub/Sub topics as the edges between them rather than as boxes. That keeps the diagram close to how people describe these systems, where the topic is the connection and not a destination.
Projects as sections
Multi-project layouts are common in GCP, often for billing or isolation rather than for architectural reasons. Drawing projects as sections keeps that structure visible without letting it become the organising principle, since the tier a component belongs to usually says more about the system than which project it is billed to.
Local, offline, your models
It runs as a desktop application. Against a local Ollama model the whole thing works offline with no API key and no telemetry, which is the practical difference from every browser-based diagram tool: your architecture never leaves the machine.
