What is an event?

Statsig records an event when your application calls the Statsig SDK to check whether a user should be exposed to a feature gate or experiment, to log a custom event (to power a metric), or to check a dynamic config.

Statsig dedupes billable exposure events for the same user and feature/experiment on client (60m window; proxy for session duration) and server SDKs (1m window; proxy for user request handling).

Experiment checks that result in no allocation (e.g. the experiment hasn’t started, or has finished) or Feature Gates that have been disabled (fully shipped or abandoned with no rule evaluation) do not generate billable exposure events.

How do I get started with the Statsig?

When you create a Statsig account, you automatically start with Statsig’s Always Free, On-demand tier where you can log up to 5 million events every calendar month for no charge.

Can I roll over any free, unused events into the next month?

No, if you don’t log up to 5 million events in a given calendar month, the remaining events balance doesn’t roll over to the next month. To maximize your On-demand benefits, we encourage you to log as many events as required to adequately capture the impact of the product improvements you’re testing.

What happens if I exceed the free events limit?

If you exceed the free events limit, you’ll start to accrue a charge at the On-demand rate with built-in volume discounts. For a given month, you accrue a charge only for events that exceed the free limit that month. Statsig alerts you via email when your usage exceeds the free limit using the email address that you used to create your Statsig account. You can also choose to lock down your account to never exceed the free limit by turning on “Automatically turn off event logging after 5 million events” in your Project Settings. When you turn on this setting, Statsig will no longer record your events though your application will continue to work and deliver the right exposures to your users as before.

What are the On-demand pricing discounts?

We like transparency and pricing should be no different. Our pricing is usage-based and the rate declines as the volume increases. The more you use, the lower the rate per event. Here’s how we calculate your price based on the number of events consumed per month.

We also offer an additional discount if you choose to commit for 12 months of usage.

When will Statsig charge me?

Statsig generates an invoice for the previous month at the beginning of each new month. When you wish to submit a payment for a given invoice, we accept your payment method via Stripe and charge the amount listed in the invoice that you wish to pay.

How do I monitor my On-demand usage?

To monitor your On-demand usage, navigate to the Project Settings and click on the Usage & Billing tab on the Statsig console at https://console.statsig.com. See our documentation for more details.
