ARCH is a local-first architecture designer for cloud and on-prem diagrams. Drag real provider components (AWS, Azure, GCP, IBM, Oracle, Alibaba, Huawei, on-prem), connect them with readable edges, nest regions/VPCs/subnets, and export presentation-ready PNG, SVG, or PDF and arch import/export.
Visualize turns JSON, YAML, Terraform/HCL, and more into charts and explorer views. No account, no server: your work stays in the browser (IndexedDB), with offline-friendly loading after the first visit.
