Real-Time Funnel Visualization

fnel provides instant, visual funnel analytics that update in real-time as user events flow in. Unlike traditional tools that require batch processing and delayed reports, you can see exactly how users are moving through your defined steps—like landing page, signup, and payment—the moment it happens. This live dashboard displays conversion rates and drop-off percentages at each stage, giving you an immediate pulse on your key user journeys without any configuration lag or complex query building.

One-Line Code Integration

Designed for developer velocity, fnel can be integrated into your application with a single line of code. After installing the lightweight npm package (npm install fnel) and initializing it with your API key, you can immediately start tracking events using simple fnel.track() calls. This eliminates the days or weeks typically spent instrumenting events and defining schemas in other platforms, getting you from zero to actionable funnel insights in under five minutes.

Smart Drop-Off Alerts

The platform automatically monitors your funnels and detects anomalies in real-time. If a particular step—such as a payment page—suddenly experiences a higher-than-normal drop-off rate, fnel triggers an immediate alert. This proactive notification system ensures you are informed of potential issues like broken forms, UX regressions, or performance problems as they happen, allowing for rapid investigation and resolution before they significantly impact conversion.

A/B Test Validation at Funnel Level

fnel allows you to attribute events to specific A/B test variants directly within your funnel analysis. By passing variant data in your track() calls, you can compare how different versions of a page or flow perform at each step of the user journey. This provides statistically significant insights into which variant drives better conversion through the entire funnel, moving beyond superficial click-through rates to understand true impact on your core business metrics.

Use Cases

fnel

Optimizing SaaS User Onboarding

For SaaS founders, understanding where new users fall off during the initial activation journey is critical. By tracking a funnel from signup and email verification to onboarding steps and final feature activation, fnel visually identifies the exact stage where users disengage. This enables targeted improvements, such as simplifying a confusing onboarding tutorial or fixing a bug in the email verification flow, directly increasing user activation rates and reducing early churn.

Fixing E-commerce Checkout Leaks

E-commerce store owners can implement fnel to visualize the classic checkout funnel: cart view, shipping information entry, payment details, and order confirmation. The real-time dashboard highlights the step with the largest percentage drop-off—for example, a 40% abandonment at the payment page—prompting immediate investigation into issues like unexpected shipping costs, lack of payment options, or form field errors that are killing conversions.

Validating Marketing Campaigns for Agencies

Marketing agencies and lead-generation businesses can use fnel to prove campaign ROI. By tracking a funnel from lead form submission through qualification steps to the final booked demo call, teams can see which traffic sources or ad creatives actually drive qualified leads through the entire pipeline, not just initial clicks. This step-level conversion data provides concrete evidence of what marketing efforts truly convert and where leads are being lost in the nurturing process.

Rapid Product-Market Fit Validation

Indie hackers and solo founders launching an MVP can use fnel to quickly gauge initial user interest and engagement. By setting up a simple funnel for their core flow—landing page visit, signup, and first key action—they can see in real-time if users are progressing or dropping off en masse. This immediate feedback loop is essential for iterating on the product experience early, before investing heavily in scaling, to ensure the solution resonates with the target audience.

Frequently Asked Questions

fnel FAQ

How is fnel different from Google Analytics or Mixpanel?

fnel is purpose-built exclusively for funnel analysis and speed of implementation. Unlike GA or Mixpanel, which are broad analytics suites requiring complex event schema design and dashboard configuration, fnel requires just one code snippet. It provides immediate, step-level funnel visualization and automated drop-off detection out of the box. There's no noise from unrelated reports—just focused insights on where users leave your core flows and what to fix next.

Is there a free plan to get started?

Yes, fnel offers a Free Starter plan designed for initial validation. It includes up to 5,000 events per month and allows tracking for up to 3 separate funnels. You get access to the real-time dashboard and basic drop-off analysis. You can start using it immediately without providing a credit card, making it risk-free to integrate and test. You can upgrade to the Pro plan when you need higher event volumes and advanced features.

What tech stack is fnel compatible with?

fnel is built for modern web applications. It is distributed as a lightweight npm package (fnel) and can be integrated into any JavaScript or TypeScript frontend application, including those built with React, Vue, Svelte, Next.js, or plain JS. The simple API (fnel.track()) sends events to fnel's backend, requiring no complex backend instrumentation, making it compatible with any server-side technology or hosting platform.

How does the A/B test validation feature work?

You can pass variant information as properties when calling fnel.track(). For example, fnel.track('pricing_page', { variant: 'annual_plan' }). fnel will then segment your funnel data by these variants, allowing you to compare the conversion performance of 'annual_plan' versus 'monthly_plan' users at each subsequent step in the journey. This provides a clear, funnel-based view of which test variant leads to more completed goals, not just initial engagement.
