Kandlit

About

Kandlit is a full-stack puzzle SaaS platform built with Vite, Supabase, and Paddle. It lets users create and play puzzles in two formats: print/KDP-ready exports and interactive digital puzzles (currently Word Guess and Sudoku, with more types plannable).

Key features:

• Full auth and subscription billing via Paddle, with regional pricing
• Digital puzzle engine with a shared, extensible puzzle system for adding new types
• Profile and stats tracking for creators and solvers, including full solve/creation history
• SEO-optimized across all pages
• Affiliate program in progress
• Clean, modern codebase with no legacy debt
• 
  

The platform is fully built and live with zero users, a strong foundation for anyone looking to launch into the puzzle/brain-games niche without building from scratch. Ideal for a buyer who wants to skip months of development and focus on growth and marketing.
