$ whatis event replay message

What counts as what

an event

One tracked action — a kilden.track() call, an autocaptured click, or a pageview. Flag evaluations and campaign triggers read events; they don't create billable ones.

a replay

One recorded session, start to finish — however long it runs. A user browsing for 40 minutes is still one replay.

a message

One email sent by a behavioral campaign. Cancelled sends — like a cart-recovery email killed by a purchase — cost nothing.

$ diff stitched-stack one-pipeline

One bill, not four.

The usual alternative isn't one competitor — it's stitching together separate analytics, messaging, flags and replay tools, each with its own SDK, its own identity graph, and its own invoice.

$ man billing

Billing questions, answered honestly

What happens when I hit the Free caps? +

Ingestion pauses until the next month — nothing is billed, nothing is deleted. Your dashboards keep working on the data you already have. Allowance resets monthly and unused amounts don't roll over.

Can I set spending limits on Pro? +

Yes — per meter. Cap events, replays and messages independently; when a meter hits its cap, ingestion for that meter pauses instead of billing past it.

How is usage measured? +

Per organization, aggregated across all its projects. Separate prod, staging and dev projects don't cost extra — they draw from the same pool.

Do you charge per seat? +

No. Unlimited team members on every plan, including Free. We charge for usage, not for people.

What about taxes? +

Handled by our merchant of record. Prices are shown in USD; local tax is added at checkout where applicable.

How do I cancel? +

Self-serve, from settings — no email, no call. Cancellation takes effect at the end of your billing period and your workspace drops to the Free tier.

The free tier is the product, not a demo.
