# FunnelKeeper + PostHog

> Product analytics as the funnel, plus the replay behind each drop-off.

The one source that is both halves at once: a product-analytics warehouse FunnelKeeper reads the funnel out of, and a replay tool it reads friction out of — on a single personal API key.

- **Category:** Product analytics
- **Access:** read-only
- **Sync:** Daily, and on demand — PostHog is rate-limited rather than metered, so Sync now works.
- **On demand:** yes — Sync now is available

## What FunnelKeeper reads from PostHog

- Sessions and engaged sessions by channel, rolled up from $pageview with first-touch attribution
- PostHog events you map to funnel stages, exactly like GA4 event maps
- Session replay links, plus $rageclick, $dead_click and $exception counts by page

## What it never does

- No writes to your PostHog project — the key needs query:read and session_recording:read, nothing more
- No video is copied. Recordings are pointers back into PostHog, where access control stays yours
- No feature flags, experiments or cohorts are touched

## How to connect PostHog

| Surface | How |
| --- | --- |
| Dashboard | Integrations → PostHog → personal API key, project id, host |
| MCP | connect_posthog, then set_posthog_event_maps |
| CLI | fk connect posthog --product <slug> |
| API | POST /products/{slug}/connections/posthog |

## FAQ

### Does self-hosted PostHog work?

Yes. The host is part of the connection, so US Cloud, EU Cloud and a self-hosted instance are all valid — paste the base URL you use for the app.

### Which scopes does the personal API key need?

query:read for the HogQL endpoint that produces sessions and mapped events, and session_recording:read for replay links and friction counts. Anything wider than that is more access than FunnelKeeper uses.

### Is FunnelKeeper a PostHog replacement?

No. PostHog is the stronger product-analytics tool and stays that way. FunnelKeeper adds the two things it does not join for you — ad spend and revenue — and returns a payback verdict per channel. Run both.
