The verdict
Seline Best for revenue tracking on a budget
Seline starts cheaper at $14/mo vs $20, and retains data forever rather than capping at 36 months. It adds native Stripe, Shopify and Polar revenue integrations with MRR tracking, plus built-in funnels. The trade-off: no free tier (Simple Analytics has one), a shorter 7-day trial, and one site per subscription versus 10.
Full profile Simple Analytics Best for migrating from GA4 across many sites
Simple Analytics offers an official GA4 import to bring historical data over; Seline has no Google Analytics import. Its entry plan covers 10 sites against Seline's 1, and adds a perpetual free tier, a 14-day trial, and built-in email reports. The trade-offs: $20/mo vs $14, and retention capped at 36 months rather than unlimited.
