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 14-day free trial, then one Pro plan at $500/month with real-time analytics, funnels, revenue tracking, API access, and unlimited websites. 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 no infrastructure work.

Where Flowsery Wins

Full-Feature Free Trial

Flowsery gives you 14 days with every feature unlocked and no credit card. Swetrix cloud also 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.

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.
