Standout Differences
Rybbit's self-hosted edition is uniquely feature-complete
Rybbit's free, self-hosted AGPL-3 build is explicitly documented as including session replay and funnels, features that many privacy analytics competitors reserve for paid cloud tiers.
Rybbit
Swetrix goes beyond web analytics into product analytics
Swetrix combines core traffic analytics with error tracking, A and B testing, feature flags, and Core Web Vitals performance monitoring, a broader feature set than Prisme or Rybbit document.
Swetrix
Prisme prioritizes real-time processing and unlimited retention
Built on ClickHouse and Grafana, Prisme is designed for real-time (not delayed) reporting and never automatically deletes visitor data, backed by a single flat hosted price of about EUR 8.99/month with no event caps.
Prisme Analytics
Rybbit is the newest and smallest of the three
Rybbit launched in 2025 and is run by a very small team, versus Swetrix (founded 2021) and Prisme, both of which have a longer operating track record worth weighing if vendor maturity matters.

Frequently Asked Questions
Which of these three is easiest to try for free?
Rybbit's free cloud tier (3,000 events per month) and fully feature-complete self-hosted edition make it the easiest to start with at zero cost. Prisme offers a 30-day free cloud trial with no credit card required, and Swetrix's self-hosted Community Edition is also free, though its cloud plans start at a paid tier.
Which tool includes session replay in its free self-hosted build?
Only Rybbit's self-hosted edition is documented as including session replay and funnels for free. Prisme's data does not document session replay at all, and Swetrix reserves session replay for its paid Plus cloud tier.
Which of the three offers built-in error tracking or A and B testing?
Swetrix is the only one of the three whose documented feature set includes error tracking, A and B testing, and feature flags alongside standard web analytics.
Are these tools GDPR-compliant without a cookie banner?
Yes, all three use cookieless tracking designed to avoid the need for a cookie-consent banner. Prisme and Rybbit both specifically document EU-based hosted infrastructure for their cloud offerings.
Which is best if I want unlimited event volume and data retention?
Prisme's hosted cloud plan is a single flat rate (about EUR 8.99/month) with unlimited websites, pageviews, events, and dashboards, and it never automatically deletes data. Rybbit and Swetrix both cap event volume by pricing tier.
How established are these three products?
Prisme's founding date is not publicly disclosed, Swetrix was founded in 2021, and Rybbit is the newest, launched in 2025. This is worth factoring in if vendor longevity and track record matter to you.
