Swetrix

Swetrix is an open-source, privacy-focused web analytics platform that collects anonymised, cookie-less metrics about website traffic, sessions, performance and client-side errors. It provides both a self-hostable Community Edition and a managed cloud offering with additional features.

Key Features

• Cookie-less, privacy-first tracking that collects anonymised pageviews, events and session data without cross-device identifiers
• Core analytics: top pages, traffic sources, UTM campaigns, geolocation and device/browser breakdowns
• Session analytics and user flows to visualise journeys and pageview sequences
• Funnels, goals and custom events for conversion tracking and behaviour analysis
• Real-user performance monitoring (TTFB, DNS, TLS, render and other frontend timing metrics)
• Client-side error tracking with aggregation by page, browser, device and geolocation
• Feature flags and rollout controls to target segments and measure feature impact
• Experiments / A/B testing (managed cloud) with exposure tracking and statistical comparisons
• Revenue analytics integrations (Stripe, Paddle) and CSV/API data export for portability
• Lightweight TypeScript tracking script and real-time React dashboard built for low overhead
• Deployable via Docker with a backend API, MySQL for core data, ClickHouse for analytics storage and Redis for caching

Use Cases

• Privacy-compliant website analytics for small businesses, blogs and SaaS sites that want to avoid cookie banners
• Monitoring frontend performance and client-side errors to detect regressions and improve page speed
• Running feature flags and A/B experiments (cloud) to optimize conversions and measure feature impact

Limitations and Considerations

• The Community Edition (self-hosted) provides core analytics, sessions, funnels, performance and error tracking but lacks some managed-cloud features (experiments, revenue analytics, AI insights, and built-in alert/email reports)
• GeoIP accuracy in self-hosted deployments depends on the chosen GeoIP database and may be less precise than the managed cloud's premium DB
• Scaling analytics requires appropriate ClickHouse and infrastructure configuration; self-hosters must manage upgrades, backups and operational costs

Swetrix bundles core web analytics, performance monitoring and error tracking in a privacy-first package suitable for self-hosting or using a managed cloud. It focuses on essential, low-footprint analytics while offering expanded features in its cloud offering.
