Analytics Tools Built for a Post-Cookie World
Privacy regulations are reshaping analytics fundamentally. We compare 6 analytics tools on data accuracy, GDPR compliance, and real-time reporting.
At MG Software we use PostHog as our primary product analytics tool due to its all-in-one approach and generous free tier. For privacy-sensitive projects we choose Plausible as a lightweight, cookie-free alternative. We often combine this with Hotjar for qualitative insights through heatmaps and session recordings.
Data-driven decision making starts with the right analytics tool, but in 2026 that choice is more complex than ever. Privacy legislation such as GDPR and the Digital Markets Act forces organizations to rethink their measurement strategy. Cookieless tracking is no longer a trend but a requirement for many industries. At the same time, product teams expect deeper insights than simple pageview counts: funnels, cohort analyses, retention curves, and real-time dashboards have become the norm. We installed six analytics tools on three production websites and compared them over eight weeks on data quality, privacy compliance, load impact on Core Web Vitals, reporting flexibility, and actual costs. The result is an honest comparison that helps you choose the right platform, whether you need to analyze website traffic, understand user behavior, or measure product adoption.
How did we select these tools?
We installed each analytics tool on three production websites and compared data accuracy, privacy compliance (GDPR), load impact on Core Web Vitals, and reporting flexibility. Costs were calculated based on 100,000 monthly page views.
How do we evaluate these tools?
- Analytics depth: pageviews, events, funnels, retention, and cohort analysis
- Privacy compliance: GDPR, cookie-free operation, and data storage location
- Integration capabilities with marketing and developer tools
- Ease of use for both marketers and developers
- Value for money and scalability as data volume grows
- Impact on page performance: script size and effect on Core Web Vitals
