FAQs

Common questions about tracking SaaS user activity with Userbook.

What is Userbook?: Userbook is user activity tracking for SaaS operators. It helps you see what users are doing, spot issues early, and understand the events behind support problems, churn risks, usage spikes, and account activity.
How is this different from analytics?: Userbook gives you analytics-like visibility, but it is built for operational user activity rather than dashboards and reports. It helps SaaS teams see what users did, spot issues, and understand the events behind support problems, churn risks, usage spikes, and account activity.
What events should I track?: Start with core SaaS lifecycle events like signup, onboarding, activation, invites, upgrades, cancellations, errors, support activity, and usage spikes. Then add the product-specific actions that signal value, risk, or cost.
Can I track custom events?: Yes. You can track standard lifecycle events and custom product events, so Userbook fits the way your SaaS actually works.
Can I add a cost to events?: Yes. Events can include cost and currency, which is useful for usage-based actions like AI generation, API calls, credits, compute jobs, or other variable-cost product activity.
Do you share my users' data?: No. Userbook does not sell or share your users' data. Data you submit about your users is used only to provide Userbook to you.
How long does setup take?: The fastest path is to paste the install prompt into Claude, Codex, or another coding agent. It can add Userbook, identify users, and track key SaaS events in one pass.
Do you have an API?: Yes. Userbook supports SDK and API-based tracking so you can identify users and send events from server-side code.
Can support teams use Userbook?: Yes. Userbook shows the events, errors, and account activity around each user, so support can understand what happened before replying.
