Both Sealmetrics and Plausible Analytics position themselves as privacy-first alternatives to Google Analytics, offering cookieless analytics that respects user privacy. But despite surface similarities, these tools take fundamentally different technical approaches—differences that dramatically impact data accuracy, legal compliance, and business outcomes.
The most critical distinction: Plausible uses hashed IP addresses for session tracking and may require consent in strict interpretations of GDPR, while Sealmetrics eliminates IP storage entirely, achieving true consentless analytics under GDPR Article 6(1)(f).
This comprehensive comparison examines both platforms across 15 key dimensions: technical architecture, privacy implementation, GDPR compliance, data accuracy, features, pricing, and real-world performance. Whether you're migrating from Google Analytics or choosing between privacy-focused alternatives, this guide provides the detailed analysis you need.
Key Comparison Points
- IP Storage: Plausible hashes and stores IPs; Sealmetrics stores zero IP data
- Consent Requirements: Plausible depends on configuration (often needs consent); Sealmetrics is consentless by design
- Data Accuracy: Plausible 20-40% loss from consent rejection; Sealmetrics 0% loss
- Pricing: Plausible starts €9/month; Sealmetrics starts €29/month (more inclusive features)
- Setup Complexity: Both offer simple implementation (~2-5 minutes)
