What's on the dashboard
- Visitors per day, red 40% under normal
- Signups and conversion rate

Connecting Plausible
- In Plausible open your account Settings → API keys.

Stats API keys only read statistics. More on Plausible →
Connecting PostHog
- In PostHog open your settings → Personal API keys (use eu.posthog.com as the host if your project is in the EU cloud).
- Create a key named “tlly” limited to your project.
- Give it only the read scopes for Query and Insights.
Scoped personal keys with read scopes can't change data or settings. More on PostHog →
