Should you build your own cookie banner? Compare custom code with a consent platform for React and Next.js, including the maintenance costs and tradeoffs.
Building your own cookie banner can look simple at first. You show a notice, store a choice, and hide the banner on the next visit.
The harder question is what the banner needs to control. A production cookie banner may need to block third-party scripts, remember preferences, support withdrawal, reflect regional rules, and keep records for accountability. For many React and Next.js teams, a maintained consent layer is a better default than a fully custom banner because it reduces infrastructure while keeping consent inside the application.
