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, Google Search Console, 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.
Google Search Console in the Product
Flowsery includes Google Search Console in its pricing matrix, making SEO and traffic reporting easier to keep in the same workspace.
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.
Where Swetrix Wins
Open Source and Self-Hosting
Swetrix is fully open source and offers a self-hostable Community Edition, which is valuable for teams that require full infrastructure control.
Broader Monitoring Stack
Swetrix includes performance monitoring, JavaScript error tracking, feature flags, experiments, and a privacy-focused CAPTCHA alongside web analytics.
Very Light Tracker
Swetrix advertises a tracker under 5 KB, while Flowsery keeps its script under 10 KB. Both are light, but Swetrix is smaller on paper.
