About CalcForge — Calculator Builder

The zero-overhead lead magnet factory for B2B.

CalcForge Overview: Stop paying developers to build simple lead-capture calculators. CalcForge is a lightweight, Vanilla JS, no-code calculator builder designed specifically for digital marketing agencies and SaaS founders. How It Works: Use the visual dashboard to drag-and-drop variables (sliders, numbers, dropdowns), write a custom math formula, and instantly generate embeddable HTML/JS code. Paste the widget on any WordPress, Shopify, or Webflow site in seconds. The "Money Maker" Feature: Webhook Lead Capture This isn't just a math tool; it's a lead generation engine. Toggle the "Lead Gate" to hide the final result until the user enters their email. The generated code seamlessly sends that email to any Webhook (Zapier, Make.com, Formspree) so you capture leads directly into your CRM. Technical Architecture: 100% Client-Side Logic: Built with pure HTML, CSS, and Vanilla JS. Zero Server Costs: No database, no backend hosting fees. State is saved via LocalStorage. Privacy-First: Secure eval logic safely processes math formulas.

Next step: 1. Launch as a Micro-SaaS: The UI is already built. Simply connect a lightweight backend (like Firebase/Supabase) to save user accounts, integrate Stripe, and charge marketing agencies $15/month to use the builder.2. Internal Agency Toolkit: Stop paying freelance developers $500 per calculator. Keep the tool private and use it internally to rapidly deploy custom lead-magnet widgets for your own clients.3. V2 "Conditional Logic" Upgrade: Expand the Javascript engine to support conditional text outputs (e.g., If result < 18, print "Underweight"). This simple upgrade instantly makes the tool highly desirable for fitness coaches and health professionals.

Reason for selling

I am a Mechanical Engineering student currently pivoting my focus toward hardware and technical robotics. While I am highly proud of the frontend architecture and logic I built for CalcForge, I do not have the marketing bandwidth to scale it as a B2B SaaS. It deserves to be owned by an agency or marketer who has the traffic to instantly monetize the lead-capture engine.
