Configuration Auditing & Drift Analysis
Use this diff engine when conducting peering checks, verifying routing policy matches, reviewing dry-runs for migration configurations, or validating fallback procedures after network alerts.
Configuration drift is a common source of silent network failure. Manual changes bypass revision tracking pipelines. Comparing running parameters against git-backed repositories using this auditor helps teams identify and patch drift anomalies.
Can it compare configurations from different vendors?
Yes, though the syntax will obviously differ. It is most effective for comparing two versions of the same vendor's config or two devices of the same model.
Does it support large configuration files?
Yes, the engine is optimized to handle multi-megabyte files smoothly within the browser.
How do I navigate between changes?
Use the floating navigation pill in the top-right of the result area to skip directly to the next or previous difference.
Is the comparison data stored on the server?
No. The diffing logic happens locally in your browser for privacy and speed. Your configuration data is not uploaded or stored unless you explicitly use a cloud-based backup feature.
What does the 'Diff Only' mode do?
It hides all identical lines and shows only the added, removed, or modified lines, allowing for a focused audit of changes.
