Built by network engineers, for network engineers. ConfigLabs is a free, independent tool that generates production-ready configs for H3C and Cisco devices — without the CLI headaches.
Start Building →Every network engineer knows the pain: you've configured the same VLAN structure a hundred times, but every time you have to look up the syntax, double-check command order, and pray you don't typo a single character. ConfigLabs eliminates that friction.
H3C uses different syntax than Cisco. Cisco IOS differs from NX-OS. ConfigLabs handles all that for you.
One missing space, one wrong VLAN ID, and your network breaks. Visual builders catch mistakes before they happen.
Stop digging through vendor docs. Build configs in minutes, not hours.
ConfigLabs started as a side project — a way to make repetitive network configuration faster and more reliable. What began as a personal tool for H3C devices grew into a multi-vendor platform supporting Cisco IOS, IOS-XE, and NX-OS, with more vendors on the way.
The mission is simple: make network engineers' lives easier, for free.
Three simple steps from blank page to deployable config:
Choose between H3C Comware or Cisco (IOS, IOS-XE, or NX-OS). The UI adapts to vendor-specific syntax automatically.
Add VLANs, interfaces, DHCP pools, OSPF, ACLs — all visually. Use a template to start fast, or build from scratch.
Click generate, copy the CLI output, paste into your switch. Production-ready, vendor-correct, and validated syntax.
Everything you need, nothing you don't:
Active development. Updates ship regularly:
No login required. No download. Just open and start configuring.
