Ops cleanup data is sensitive by default: event taxonomies, campaign URLs, support macros. Shipping that to another SaaS for a one-off normalize pass is usually the wrong trade.
Taxon, Utmend, and Macrow run in the browser. Parse, cluster, preview, and export happen on the machine that opened the tab. There is no upload step — and no account wall to start. Local-first.
- Taxon — Amplitude / Mixpanel / Heap CSV stays local.
- Utmend — URL lists stay local.
- Macrow — macro CSV stays local.
The marketing pages use privacy-light analytics (anonymous pageviews only). File and URL contents are never part of that count. That is the contract: make the messy legible without moving the pile.
