Check your numbers without leaving your editor
Connect Claude Code, Cursor, or any MCP client with a scoped key, and your agent can pull traffic, read investigations, and set up funnels, goals, and flags for you.
Swap a stack of tools for one.
One tracker collects analytics, errors, and web vitals, and the same dashboard runs your funnels, flags, links, and uptime.
See the whole story in one place
A new error, a slow page, and a drop in signups show up side by side, so you can see how they connect.
Respect your visitors' privacy
No analytics cookies, and you decide whether events link to your own user profiles.
Keep your pages fast
The tracker is about 13 KB gzipped and loads asynchronously, so it stays out of your visitors' way.
Never get locked in
Databuddy is open source. Read the code, or run it on your own servers.
Watch launches as they happen
Follow visitors and events live while a launch or campaign goes out.
Get answers in plain words
Ask Databunny about traffic, conversions, errors, or performance, and see the evidence behind each answer.
