The problem
Spreadsheets break at scale.
Manually mapping thousands of URLs takes days and is highly error-prone.
Missed redirects cause 404s, lost rankings and broken user journeys.
Spreadsheets can't explain why two URLs match — making QA painful.

Domain & locale mapping
Map between domains and language prefixes (/nl, /en, /de) automatically.

Use cases
Built for the migrations that matter most.
01
Replatforming
Moving from one CMS to another with completely new URL structures — without dropping a single ranking page.
The biggest risk in any replatform isn't the build — it's the redirect map. We turn 80 hours of mapping into an afternoon.
Magento → Shopify — category & product flows
WordPress → Headless — slug normalization
Custom CMS migrations — any source format
Bulk auto-accept — 92%+ confident matches
02
Domain consolidation
Merging multiple domains or subdomains into one canonical structure with safe locale-aware redirects.
Multi-brand mergers and international consolidations need locale guards — match nl/de/en separately, not as one pile.
Multi-brand merge — preserve link equity
Subdomain to folder — blog., shop. → /
International consolidation — per-locale matching
Locale guard — no cross-language mixups
03
Site restructure
Reorganizing URL hierarchy, renaming categories or normalizing slugs — without breaking link equity.
Even small slug changes accumulate fast. Pattern recognition picks up entire family rewrites in one pass.
Category renames — family-level mapping
Depth changes — /a/b/c → /a/c flattening
Slug normalization — casing, dashes, accents
Pattern detection — auto-learn rewrites
