Honest differences.

Vector 5 is a clean-room product. It is not a fork of any tool named here and is not affiliated with them. Where they do something well, this page says so.

Same as the best privacy-first tools

Cookieless, no fingerprinting, no stored IPs.
Realtime, pages, sources, geo, devices, goals, UTM campaigns.
Self-hostable with Docker Compose, free forever.
A lightweight script you can read in one sitting.

Only Vector 5

An actor on every event — humans, humans via AI, crawlers, agents, bots — and a filter for it on every report.
A server-side middleware so visitors that never run JavaScript still exist in your data.
A public collection manifest per site, so “private” is a document rather than a slogan.
AI insights that only ever see aggregates, with Ollama as a first-class provider.
An MCP server so your agents can read the same numbers you do.

Yes Partial No“-class” columns describe a category of tools, not one vendor. Corrections welcome on GitHub.

Coming from Plausible-class

You will feel at home in a minute. Add the middleware and your “Direct” bucket shrinks as assistant referrals and crawlers get names.

Coming from Umami / Rybbit-class

Same self-host story. What changes is the actor model and a chat that reads rollups, not raw events.

Coming from Google Analytics

You lose per-user funnels and cross-site identity — deliberately. You gain a consent-free script, an audience you can explain, and every AI visitor GA never sees.
