Flowsery vs Swetrix
Two privacy-first analytics tools compared for teams choosing between hosted simplicity, open source, and deeper business reporting.
Last updated: April 2026
TL;DR
Swetrix is an open-source, cookie-less analytics platform with self-hosting, performance monitoring, error tracking, funnels, experiments, feature flags, CAPTCHA, and API access. Its cloud product has a 14-day trial and starts at $19/month for 100k events when billed yearly. Flowsery is cloud-hosted and starts with a permanent free tier for up to 5k events/month, then paid plans from $19.99/month with real-time analytics, funnels, revenue tracking, API access, and unlimited sites on paid tiers. Choose Swetrix if open-source self-hosting, error monitoring, or experiments matter most. Choose Flowsery if you want a managed, revenue-first analytics dashboard with a free entry point and no infrastructure work.

Where Flowsery Wins
Permanent Free Tier
Flowsery gives small sites a free plan for up to 5,000 events per month. Swetrix cloud starts with a 14-day trial and requires a paid subscription after that unless you self-host the Community Edition.
Managed Revenue-First Workflow
Flowsery is built around traffic, funnels, goals, customer journeys, and revenue attribution in one hosted dashboard. You get business reporting without operating your own analytics stack.
No Self-Hosting Maintenance
Swetrix is attractive when you want open-source control. Flowsery is better when you want updates, scaling, and infrastructure handled for you.

Open Source and Self-Hosting

Broader Monitoring Stack
Swetrix includes performance monitoring, JavaScript error tracking, feature flags, experiments, and a privacy-focused CAPTCHA alongside web analytics.
Very Light Tracker
