ARCH

ARCH is a browser‑based tool for creating cloud and network diagrams. It lets users assemble architecture components by dragging and dropping them onto a canvas, connecting them with orthogonal lines, and organizing work into separate projects. All editing and rendering happen locally, so no server or cloud service is required to use the application.

The software supports exporting designs in the .arch file format, enabling users to preserve their diagrams for later editing or integration with other tools. Because it runs entirely in the browser, it can be accessed from any device with a modern web engine without installing additional software.

Targeted at individuals and teams who need to prototype or document production‑grade cloud infrastructures, ARCH provides a lightweight, offline‑first environment for visualizing and iterating on architectural layouts. Its experimental status indicates ongoing development and potential feature expansion.
