Klar vs. Plausible
Two privacy-first analytics tools, side by side. Both are cookie-free, both are GDPR-friendly by default. Here's how they actually differ.
Short answer: both are excellent privacy-first analytics with no cookies and no fingerprinting. Klar ships a slightly heavier tracker (~1.9 KB vs ~1.3 KB gzipped), richer custom-event properties (up to 50 per event vs Plausible's conversion-goal model), and built-in SPA auto-tracking. Plausible is more mature, has a larger community, and supports a richer revenue attribution story. If you mainly need pageviews + a handful of conversion goals and want the most popular choice, Plausible is the safe pick. If you need granular event properties and built-in SPA support out of the box, Klar is the better fit — at about 600 bytes more on the wire.

data-plausibleattributes on every link. - You need rich event payloads — Plausible's conversion-goal model caps you at simple event names; Klar's custom events support up to 50 properties per call.
- Your users care about DNT — Klar honors
Do Not Trackviadata-honor-dnt; Plausible does not. - You want SPA auto-tracking and rich event properties out of the box — at ~1.9 KB vs ~1.3 KB Klar costs about 600 bytes more on the wire; the difference is what the tracker can report.
- You want anonymous identification with persistent properties (e.g. "this visitor logged in 3 times last month" without ever storing an email or IP).
When Plausible wins
- You want the most popular privacy-first choice — Plausible has a much larger community, more third-party tutorials, and broader name recognition in the indie/SaaS market.
- You need built-in revenue attribution — Plausible's first-party revenue events are more polished out of the box; Klar's revenue story is "use custom events".
- You want funnel reports without setup — Plausible funnels are a first-class feature (paid plans); Klar funnels require you to define them in your event taxonomy.
- You need to self-host — Plausible provides an AGPL-licensed Community Edition for Elixir/Postgres; Klar is available only as a hosted service.
