Linkfolio

A link-in-bio SaaS: create one shareable page for all your links and see which ones your audience actually clicks. Free tier plus a paid Pro plan.

Live demo: https://linkfolio-name-6af4.vercel.app (example page: https://linkfolio-name-6af4.vercel.app/u/demo)

Features

• Email magic-link and Google sign in (Supabase Auth)
• Public page at /u/username, mobile-first
• Link editor with reordering and active/inactive toggle
• Click analytics dashboard (totals and per-link, over time)
• Monthly subscription with Stripe (Free vs Pro), managed via the Stripe Customer Portal
• Per-user data isolation with Postgres Row-Level Security

Tech stack

• Next.js (App Router, TypeScript) + Tailwind CSS
• Supabase (Auth, Postgres, Storage, RLS)
• Stripe (Checkout, Customer Portal, webhooks)
• Deployed on Vercel

Security notes

• Tables are private by default; RLS restricts every row to its owner.
• Public pages are served through a security definer RPC that returns only safe fields, so internal columns (Stripe IDs, plan) are never exposed to the anonymous API.
• Click logging goes through a register_click RPC that derives the owner from the link, instead of trusting client-supplied values.
