Rack Planner – web tool to design 10" mini racks with snap‑to‑grid
Rack Planner lets you drag and snap hardware modules onto a 10" mini‑rack grid, enforcing half‑U spacing and depth limits so designs are physically buildable. The layout is stored in the URL and localStorage, and can be exported as SVG or PNG. It includes a pure‑JavaScript geometry core with tests, undo/redo, and auto‑placement logic. Ideal for hobbyists and small‑scale datacenter builders who need a quick, offline rack design tool.
