What it does

Databuddy gives startups a self‑hosted product‑analytics dashboard (visitors, events, funnels, goals) plus an AI analyst (Databunny) to answer data questions without using cookies.

When to use it
  • •You need a privacy‑first analytics stack you can host yourself instead of a SaaS tracker.
  • •You want to run A/B tests or feature‑flag rollouts and see the impact in a single dashboard.
  • •Your team wants to ask natural‑language questions about user behavior and get instant AI‑generated insights.
Ready-to-paste prompt
In the Databunny chat box type: `What is the conversion rate from the "signup" event to the "purchase" event for users who joined the "beta" feature flag in the last 14 days?`
Heads up: Databuddy will not start without a valid OpenAI API key – the service fails at launch if `OPENAI_API_KEY` is missing or malformed.
