Flowsery vs Seline

Two modern, privacy-friendly analytics products compared for revenue, profiles, funnels, AI, and pricing.

Last updated: August 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 $14/month for 25k pageviews after a 7-day free trial, and it does not publish a permanent free plan. Flowsery starts with a 14-day free trial and then Team at $250/month or Pro at $500/month, with privacy-first analytics, funnels, customer journeys, revenue attribution, and API access. Choose Seline if you want profiles, AI/MCP workflows, and a very small script. Choose Flowsery if you want a longer trial, every feature bundled into each plan, and a more conservative no-personal-data default for website analytics.

Where Flowsery Wins

Fully Hosted, Two Plans

Flowsery is fully hosted with a 14-day free trial and two plans: Team at $250/month and Pro at $500/month. Seline offers a 7-day trial and states that it does not have a free plan either.

Longer Free Trial

Flowsery gives you 14 days to test everything without a card, while Seline offers 7. Seline Pro then starts at $14/month, below Flowsery Team at $250/month.

Privacy-Conservative Default

Flowsery is built around no cookies, no stored IP addresses, no fingerprinting, and no personal data collection. Seline is cookie-free by default, but profiles can include emails, names, and other custom data when teams opt into identification.

Where Seline Wins

Very Small Script

Seline advertises a roughly 2 KB script, which is smaller than Flowsery’s sub-10 KB script.

AI and MCP Workflows

Seline has a built-in AI assistant and MCP server that can query analytics data from AI tools.

Profiles and Churn Filters

Seline’s profile system can attach user attributes, support Stripe workflows, and power churn and engagement filters for SaaS teams.
