Config Tools

Config Diff

Compare before-and-after router or switch configurations directly in the browser. The result view is optimized for Cisco-style and text-based network configs.

Use the ignore options when you want to focus on meaningful changes instead of formatting noise.

Config A (Before)

Config B (After)

Ignore blank lines Ignore comment lines (! or #)

Inputs

Two configuration blocks (running, candidate, or backup)
Optional toggle for whitespace-only differences

Outputs

Side-by-side coloured diff
Summary counts of additions, removals, and changes

Use Cases

Pre-change review against the running config
Comparing two backups to find recent drift
Reviewing a teammate's proposed change

Limitations

Plain-text diff; no semantic understanding of vendor syntax
Output is for review only — does not push to devices
