Real-Time Funnel Visualization
fnel provides instant, visual dashboards that map out your user journey step-by-step. 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. Within minutes, you can start tracking events and seeing your funnels populate in the dashboard, allowing you to focus on analysis instead of tool configuration.
Smart Drop-Off Alerts
fnel automatically monitors your funnels and sends you alerts when it detects a significant drop-off at any step. For example, if the conversion rate from your payment page suddenly plummets, fnel will notify you immediately. This proactive feature helps you catch issues as they happen, so you can investigate and fix problems like broken forms or confusing UX before they cost you more conversions.
Built-In A/B Test Validation
Move beyond vanity metrics with fnel's A/B test analysis. You can easily tag events with test variants, and fnel will compare how each variant performs at every step of your funnel. This gives you a clear picture of which version actually improves your conversion rate, not just which one gets more clicks, helping you make confident decisions based on step-level performance data.
Ninjasell
AI Listing Builder
This powerful feature acts as your 24/7 market research assistant. Simply upload your design and select a product category. The AI instantly analyzes hundreds of top-selling Etsy listings in your niche to understand what works. It then automatically generates a complete, optimized listing for you, including a compelling title, search-friendly tags, a persuasive description, and proper SEO—all based on real data from products that are actually making sales. This takes the guesswork out of listing creation and gives every design its best chance to succeed from the moment it goes live.
Pro Mockups & ReSpark Automation
Ninjasell generates beautiful, Etsy-optimized mockups by studying the visual styles and aesthetics that perform best on the platform. Furthermore, the innovative ReSpark feature automatically monitors your listings. If a product gets zero sales for 90 days, ReSpark jumps into action. It analyzes current Etsy trends and regenerates the listing with fresh, high-intent titles and tags to give underperforming designs a new lease on life, all without you lifting a finger.
Trademark Check & White-Label Fulfillment
Protect your store from costly takedowns with the built-in, free USPTO trademark scanner. Check your designs and titles for potential conflicts instantly before publishing. When orders do come in, Ninjasell's white-label fulfillment service handles everything. They print your design on a curated catalog of quality products (like t-shirts, mugs, and candles) and ship them directly to your customer with no Ninjasell branding, ensuring a professional, seamless experience from your store to their doorstep.
Pinterest Auto-Poster & Market Intelligence
Grow your traffic hands-free with the Pinterest Auto-Poster. It automatically publishes your new products to relevant, high-traffic Pinterest boards with SEO-optimized pin descriptions, turning your catalog into a self-marketing engine. Additionally, the Market Intelligence tools help you stay ahead of the curve by revealing trending niches, sales velocity of products, and low-competition opportunities before they become saturated, informing your next design decisions.
Use Cases
fnel
Optimizing SaaS Signup Flows
For SaaS founders, the journey from visitor to activated user is critical. fnel helps you track each step—landing page view, signup form submission, email verification, and onboarding completion. By visualizing where potential customers drop off, you can pinpoint issues like a confusing form or a lengthy verification process and make targeted improvements to boost your activation rate.
Fixing E-commerce Checkout Leaks
Abandoned carts are a major pain point for online stores. With fnel, you can visualize the entire checkout funnel: cart view, shipping information entry, payment processing, and order confirmation. Seeing the exact step where shoppers leave allows you to identify and fix problems, such as unexpected shipping costs or a cumbersome payment gateway, to recover lost sales.
Proving Marketing Campaign ROI for Agencies
Marketing agencies and freelancers can use fnel to demonstrate the true effectiveness of their campaigns for clients. By tracking a lead generation funnel from form submission to qualification call booking, you get clear, visual proof of which campaigns are driving qualified leads and where in the process they succeed or fail, making reporting transparent and actionable.
Validating Product Changes & New Features
When you launch a new feature or redesign a key page, you need to know its impact on user behavior. fnel allows you to create a funnel for the new user path and compare it to the old one. You can see if the change improved conversions at specific steps or introduced new friction, providing data-driven validation for your product decisions.
