About fnel
fnel is a funnel analytics tool designed for the modern, mobile-first builder. It cuts through the noise of traditional analytics by focusing on one critical question: where are users dropping off in your key conversion flows? Built specifically for solo founders, indie hackers, and early-stage startups, fnel eliminates the complexity and setup headaches of platforms like Google Analytics or Mixpanel. Its core value proposition is speed and clarity. With just a single line of code, you can start tracking events and immediately visualize your funnel in real-time. There are no endless dashboards to configure or complex schemas to learn. Instead, you get a clear, actionable view of user behavior from landing to activation, checkout, or lead conversion. This laser focus helps you quickly identify leaks, validate A/B tests, and optimize for growth without wasting precious development or analysis time. fnel is the essential tool for anyone validating an idea, running a side project, or scaling a SaaS product who needs to make data-driven decisions fast and get back to building.
Features of fnel
Real-Time Funnel Visualization
See exactly where users drop off in your conversion process the moment it happens. fnel provides instant, clear visualizations of your defined funnel steps, showing user counts and conversion percentages at each stage. This live dashboard updates continuously, so you don't have to wait for data to process or refresh pages manually. It transforms raw event data into an immediately understandable story about user behavior, allowing you to spot issues like a sudden increase in cart abandonment or a problematic step in your onboarding flow as they occur, enabling rapid response.
One-Line Code Setup & Event Tracking
Get started in minutes, not days. Integrating fnel is designed for developer-friendly simplicity. You install one lightweight package, add your API key, and start sending events with straightforward fnel.track() calls. There's no complex configuration, no tagging manager, and no need to define schemas upfront. You can track standard funnel steps like 'signup' or 'payment_page', and even add metadata for A/B testing variants directly within the track call. This minimal setup gets you from zero to actionable insights faster than any other analytics tool.
Smart Drop-Off Alerts & Detection
fnel proactively monitors your funnel health. Instead of requiring you to constantly check dashboards, its system automatically detects when a step in your funnel suddenly starts underperforming. You'll receive clear alerts highlighting significant conversion leaks, such as "High drop-off detected at Payment Page (40.1%)". This feature acts as an early warning system, ensuring you're immediately aware of critical issues that could be costing you conversions, so you can investigate and fix problems before they impact your business goals.
A/B Test Validation at the Funnel Level
Move beyond vanity metrics and understand the real impact of your tests. fnel allows you to compare A/B test variants based on their performance through your entire conversion funnel. You can see not just which variant got more clicks, but which one led to more users successfully completing the signup, checkout, or activation process. The platform displays confidence levels for your tests, giving you reliable data to decide whether a change—like a new button color or signup flow—genuinely improves your bottom-line conversions.
Use Cases of fnel
Optimizing SaaS User Onboarding
For SaaS founders, the journey from signup to activated user is critical. fnel helps you track each step—landing page view, signup form submission, email verification, initial onboarding, and final activation. By visualizing this funnel, you can pinpoint where new users get confused or lose interest. For instance, if there's a massive drop after 'email_verification', you might need to simplify that process. This insight allows you to iteratively improve the onboarding experience, reduce churn, and increase the number of users who find value in your product.
Reducing E-commerce Checkout Abandonment
E-commerce store owners can use fnel to map the checkout funnel: cart view, shipping information entry, payment page, and order confirmation. The real-time visualization shows the exact percentage of users lost at each stage. Seeing a 40% drop at the payment page, for example, is a clear signal to investigate issues like unexpected fees, lack of payment options, or technical errors. By fixing these specific, identified leaks, you can directly recover lost sales and increase your overall conversion rate without guessing which part of the checkout to optimize.
Measuring Agency Lead Generation Campaigns
Marketing agencies and consultants running lead-gen campaigns need to prove ROI. fnel enables tracking of a lead funnel: form submission, lead qualification, and booked call. By connecting this funnel data to specific campaigns (using UTM parameters or event properties), you can see which marketing efforts are actually generating qualified leads and booked calls, not just form fills. This provides concrete, funnel-based evidence of what's working, allowing for smarter budget allocation and clearer client reporting.
Validating Product-Market Fit for New Ideas
When validating a new product or feature, indie hackers need fast, clear feedback. fnel's simplicity is perfect for this phase. You can quickly instrument a minimal landing page or prototype to track a simple funnel like 'landing_page' -> 'waitlist_signup' or 'feature_view' -> 'feature_use'. The immediate visual feedback shows you if people are engaging with your core value proposition. The low setup cost and focus on the conversion funnel help you learn rapidly and decide whether to pivot or persevere, all without the overhead of a complex analytics suite.
Frequently Asked Questions
How is fnel different from Google Analytics or Mixpanel?
fnel is purpose-built for one thing: understanding funnel conversion and drop-off with speed and simplicity. Unlike GA or Mixpanel, which are powerful but complex platforms requiring extensive setup, schema design, and dashboard configuration, fnel gets you actionable funnel insights with one line of code. It provides step-level analysis and automatic drop-off detection out of the box, removing the noise and learning curve. It's designed for founders and small teams who need answers quickly, not data analysts managing a vast data warehouse.
Is there a free plan to get started?
Yes, absolutely. fnel offers a Free Starter plan that requires no credit card to begin. It includes up to 5,000 events per month, allows you to track up to 3 different funnels, and provides access to the real-time dashboard with basic drop-off analysis. This plan is perfect for validating your idea, testing the tool on a side project, or for early-stage startups with lower traffic. You can upgrade to the Pro plan at any time when you need higher event volumes and more advanced features.
What happens if I exceed my monthly event limit?
If you are on the Free Starter plan and exceed the 5,000 monthly event limit, your tracking will continue to function, but you will be prompted to upgrade to the Pro plan to view analytics for the new data and continue receiving real-time insights. The Pro plan offers a much higher limit of 100,000 events per month. It's designed to ensure that growing products can continue to use fnel without interruption as their user base expands.
