Performance analytics tools: pick a decision, not a dashboard
"Performance analytics tools" is a category that contains three different products wearing the same badge:
Product analytics — what users do (PostHog, Amplitude, Mixpanel).
Attribution suites — which ad got the click (Cometly, Hyros, Northbeam, Triple Whale).
The money layer — did the spend pay back (this is FunnelKeeper).
If you buy (1) expecting (3), you will have beautiful funnels and no idea whether Meta made money. If you buy (2) expecting (3), you will have a ROAS tile and a four-figure invoice.
What the category should mean
A performance analytics tool, for a small SaaS or a vibe-coded app, has to answer four questions:
Which channel brought the customer.
What they did in the product (enough to know they activated).
What they paid you, in your currency, from your books.
Whether (3) has crossed (1)'s CAC yet.
Most tools in the category stop at (1) or (2). The join is the product.
A short buyer's grid
If you need… | Buy |
|---|---|
Session replay, flags, experiments | |
Shopify / DTC creative + Triple Pixel | |
High-ticket call tracking | |
Enterprise multi-touch for a large DTC account | |
Agency-scale paid-media attribution | |
Payback day, LTV:CAC, human-approved ad ops, an agent API | FunnelKeeper |
The honest row: FunnelKeeper is not a performance analytics suite in the G2 sense. It does not replace PostHog. It sits next to it and does the join those tools leave on the warehouse floor.
What to ignore on the pricing page
"AI insights." If the insight cannot be a card with one number and two buttons, it is an essay. We do not ship essays.
ROAS as the headline metric. See ROAS meaning vs payback.
A model that assigns every dollar to a channel. Unattributed revenue is a real category. A tool that refuses to show it is selling completeness.
The setup test
A tool that takes a weekend to instrument is the wrong tool for a product you shipped in a weekend. The test:
Can your coding agent connect the sources, or is there a two-week professional-services row?
Is spend read-only until a human approves a change?
Can it take revenue from a database, not just a checkout pixel?
FunnelKeeper's answers are yes, yes, and yes. MCP, CLI and the dashboard are the same API. Start free — 30 days of Growth, no card.
FAQ
Is FunnelKeeper a performance analytics tool? It is a money layer. If your RFP says "performance analytics," we will lose to PostHog on replay and to Cometly on pixel-level MTA. If your actual question is payback, we are the shorter list.
Can I use FunnelKeeper with PostHog? Yes. PostHog can be a source. GA4 still owns traffic volume when both are connected.
What about the long SaaS think-piece on performance analytics? There is a scheduled essay at /blog/performance-analytics that covers the category in depth. This page is the buyer's cut.
