Plan your racks.
Design every panel.
nice-rack! is a visual tool for designing server room layouts and electrical panel enclosures, mapping port-level cabling, and producing documentation your team can actually use.
What it looks like
Real rack diagrams, built in minutes
Rack A — Compute
Rack B — Edge / DB
Color-coded by device category
Features
Everything a data-center engineer needs
Visual rack planning
Place devices into U-slots with drag-and-drop precision. See your infrastructure at a glance across multiple racks.
Port-level cabling
Connect individual ports with typed cables — RJ45, fiber, or power. Type compatibility is enforced automatically.
Device library
Ships with common generics for servers, switches, PDUs, and patch panels. Add custom devices with your own frontplate images.
Multi-org workspaces
Keep clients and teams completely separate. Invite colleagues with scoped roles and manage access from one place.
Printable diagrams
Export clean rack-sheet PDFs ready for data-center handoffs, audits, or change-management documentation.
Tag & annotate
Label devices, attach notes to connections, and search your entire library by name, category, or tag.
DIN rail panel planning
Design electrical enclosures with DIN rail modules — PLCs, I/O, breakers, relays, contactors — placed by width in mm across multi-row rails.
