Flowsery vs Seline
Two modern, privacy-friendly analytics products compared for revenue, profiles, funnels, AI, and pricing.
Last updated: April 2026
TL;DR
Seline is a polished, EU-based analytics platform with a roughly 2 KB script, visitor journeys, profiles, funnels, revenue tracking, Stripe integration, public API, and an MCP server for AI tools. Its Pro plan starts at $24/month for 100k events after a 7-day free trial, and it does not publish a permanent free plan. Flowsery starts with a permanent free plan for up to 5k events/month and paid tiers from $19.99/month, with privacy-first analytics, funnels, customer journeys, revenue attribution, Google Search Console, and API access. Choose Seline if you want profiles, AI/MCP workflows, and a very small script. Choose Flowsery if you want a free hosted plan, lower paid entry point, and a more conservative no-personal-data default for website analytics.

Where Flowsery Wins
Free Hosted Plan
