Zach Waterfield, founder of Kopa and Toad, has developed a link shortening tool with simple APIs for low-coders. Toad provides an easy-to-use dashboard, analytics, and API designed specifically for low-coders. The project was built using a serverless Supa-stack consisting of Supabase, Lambda functions, Next.js, TailwindCSS, and Vercel to achieve low-management overhead. This setup allows Zach to focus on the creative process and quickly launch services like Toad with all desired functionality.
