Real-Time Funnel Visualization
fnel provides an instant, visual dashboard that maps your user's journey step-by-step. You can see exactly how many users progress from one stage to the next, such as from landing page view to signup form submission to payment completion. The interface displays conversion rates and user counts at each step in real-time, eliminating the lag and guesswork. This immediate feedback loop allows you to monitor the impact of changes as you make them, turning analytics from a retrospective report into an active optimization tool.
Smart Drop-Off Alerts
The platform automatically monitors your funnel steps and detects anomalies. If a particular step, like a payment page, suddenly starts underperforming with a higher-than-usual drop-off rate, fnel will trigger an alert. This proactive notification means you don't have to constantly watch the dashboard. You're immediately informed of potential problems—such as a broken form or a confusing UI element—enabling you to investigate and fix conversion leaks faster than ever before.
A/B Test Validation at the Funnel Level
fnel allows you to attribute events to specific A/B test variants, enabling step-level conversion analysis. Instead of just looking at overall click-through rates, you can see which variant of a pricing page or CTA button leads to more users actually completing the subsequent signup or purchase steps. This provides much deeper validation than vanity metrics, giving you clear, funnel-based evidence on what truly drives users toward your final conversion goal.
One-Line Code Setup & Developer-Friendly Design
Integration is designed for maximum speed and minimal friction. After installing the fnel package, you simply initialize the library with your API key using one line of code. From there, you can start tracking events immediately. There's no complex configuration, no need to define schemas upfront, and no overwhelming admin panels. This simplicity ensures developers and founders can implement robust analytics in under five minutes and return to building their product.

Optimizing SaaS User Onboarding
For SaaS founders, the journey from signup to activated user is critical. fnel can track steps like landing page visit, account creation, email verification, initial onboarding tutorial, and first key action completion. By visualizing this funnel, you can pinpoint where new users get confused or disengaged. For instance, a major drop-off after email verification might indicate a problem with the verification email itself or the next step's clarity, allowing you to streamline the path to activation.
Fixing E-commerce Checkout Leaks
E-commerce store owners can use fnel to map the checkout process: cart view, shipping information entry, payment details submission, and order confirmation. Seeing the conversion percentage at each stage reveals where customers abandon their carts. A significant drop at the payment page could signal issues with payment gateway reliability, unexpected fees, or a lack of trusted payment badges, enabling targeted fixes to recover lost sales.
Validating Marketing Campaigns for Agencies
Marketing agencies and consultants running lead generation campaigns can prove their ROI by tracking a client's lead funnel. Steps can include form submission on a landing page, lead qualification, and scheduled discovery call. By connecting this funnel data to specific campaign sources (using UTM parameters or event properties), agencies can demonstrate exactly which campaigns generate not just clicks, but qualified leads that move through the entire sales pipeline.
Tracking Side Project or MVP Validation
Indie hackers and builders launching a new product idea need to validate interest quickly. fnel is perfect for tracking a simple, crucial funnel for an MVP, such as "Visitor -> Waitlist Signup -> Beta Access Granted." This provides immediate, clear data on conversion rates from traffic to committed interest, helping decide whether to pivot or persevere without investing in complex analytics infrastructure prematurely.
