You can see exactly how many users move from one stage to the next, like from landing page to signup to payment, and identify the precise point where they leave. This real-time view means you don't have to wait for data to process or build complex reports; you get immediate insights into your funnel's performance so you can start optimizing right away.

One-Line Setup & Zero Configuration

Getting started with fnel is incredibly simple. You just install the fnel package and add a single snippet of code with your API key to your project. There's no complex schema to define, no tags to manage, and no days spent on setup.

Smart Drop-Off Alerts

fnel automatically monitors your funnels and sends you alerts when it detects a significant drop-off at any step.
