SkynetLabs Toolkit
A free-tool sandbox that does the work traditional SaaS lead magnets pretend to do — 47 real calculators and planners, all shipping, all tracked.
Problem
Agency lead gen via gated PDFs is dead. Free tools that actually work are the new top-of-funnel. Competitor tools are either behind paywalls or broken.
Approach
Built a modular tool system on React + Vite with Supabase as the shared analytics + user store. Each tool is a self-contained component sharing a design system. Deploy = single Vercel build.
What shipped
- 47 live tools across categories
- Supabase analytics with per-tool event tracking
- Email capture → CRM sync
- Social share graph generator per tool
- Monorepo structure for rapid new-tool addition
Outcome
Free-tool lead-gen platform used by freelancers and small agencies for ROI calculations, rate planning, scope tracking, and client onboarding. Each tool logs usage to Supabase for analytics and retargeting.
Lessons
Tool usage-rate is a better signal than email-capture rate for downstream conversion. Ship 10 tools before optimizing any of them.
