squinch Pre-alpha

Your coding agent already knows the architecture.
Now it can draw it.

Describe the system in a paragraph. Squinch renders it precisely — real layout control, vendor-accurate icons, and diagrams you can zoom into, from the whole landscape down to one service's internals.

A paragraph is typed into a prompt box describing a products API on AWS. A status line reads Thinking, then Using squinch skill, then Finalizing diagram, and the finished diagram rises underneath it, every element from the sentence drawn with its real vendor icon.

On a landscape of five systems, clicking a service card opens it into its own internals while the rest stay as muted context. The breadcrumb closes it again, and the view cuts to full detail with every system open at once before returning to the landscape.

Multiple altitudes, one model

Zoom into any system

Every system opens into its own internals with one click and zooms back out just as easily — landscape, service and everything between are views of one model, not separate diagrams to keep in sync.

Motion carries meaning

Packets down a queue, a slow dashed archive job, a comet on the final push — cadence you can read, from CSS keyframes and never script.

A notification pipeline: events queue, a worker archives and pushes to the customer

Real deployment boundaries

VPCs, subnets, cloud and on-prem zones: nested, tinted by kind, labelled where you'd expect them.

1,302 vendor icons

AWS, Azure, Kubernetes and the products around them — Kafka, Postgres, Datadog — not grey boxes with labels inside.

Beyond the clouds — product logos alongside cloud vendor icons
