PostHog

Open-source product analytics with session recording, feature flags, and heatmaps. Self-hostable.

Configure

{
  "integrations": {
    "posthog": "phc_abc123..."
  }
}

Where to find your project api key

PostHog project → Project settings → Project API key (starts with phc_).

Or set it from the dashboard — Editor → Configurations → AI & Advanced → Integrations.

Gotchas

• EU residents using eu.posthog.com — the default host is app.posthog.com. If you need EU-region data, fork our integration or wait for the posthogHost override (roadmap).

Loading behavior

• Strategy: afterInteractive — injected after page interactivity, so it never blocks first paint.

• CSP: if you enforce a Content Security Policy, allowlist https://app.posthog.com in script-src.

• Removal: delete the integrations.posthog key (or blank it in the dashboard) and redeploy — the script disappears on the next page load.
