Replaces these SaaS

• Amplitude · Product analytics / event tracking / funnels

  Plausible is more web-analytics-shaped than product-analytics-shaped — it replaces Amplitude only if your usage was mostly pageview / event count / referrer reporting, not deep funnels. Swap the snippet on your site, optionally backfill historical events via the import-from-GA tool (no Amplitude importer; you'd write JSON → Plausible Events API yourself).

• Fathom Analytics · Privacy-first web analytics

  Use the official compose at github.com/plausible/community-edition. Replace the Fathom snippet with Plausible's `<script defer data-domain="yoursite.com" src="https://plausible.example.com/js/script.js">`. There's no first-party Fathom importer (Fathom doesn't expose historical pageview data via API) — accept the calendar reset and start clean. Goals and custom events port one-for-one with the same hash-based event API.

• Google Analytics · Web analytics

  GA does not export raw events for free, so historical-data migration is impractical. Practical path: install both side-by-side, drop the GA snippet after a 30-day overlap. Plausible imports GA4 metadata (property → site mapping) via Settings → Import from Google Analytics if you connect the GA API once.

• Mixpanel · Product analytics

  Plausible is page-view + custom events, not full event analytics. Replace Mixpanel only if your usage is pageviews + a handful of named events. No Mixpanel importer; track forward.
