React Migration Project

View scoping doc here

Overview

We are migrating the marketing site to a modern stack using Next.js 15 + TypeScript, Sanity CMS, and a shared UI package. This migration will improve SEO, enable dynamic content management, and provide a scalable foundation for future development.

The work will be structured into weekly milestones, with the goal of launching in ~5 weeks while maintaining feature parity with the existing Framer site.

Proposed Tech Stack

• Next.js 15 + TypeScript + React for site framework
• Sanity CMS for content management
• Storybook for component documentation
• TailwindCSS + Framer Motion for UI and animations
• Mixpanel for analytics and tracking
• Netlify for deployment

Milestones

• Week 1: Foundation
• Week 2: Components
• Week 3: Pages
• Week 4: CMS + Analytics
• Week 5: Launch

Migration Plan

Development will proceed in parallel while the current Framer site remains live.
A content freeze ~3 days before launch will ensure full parity before cutover.

Launch Checklist

• Configure SEO + redirects
• Optimize performance (images, Lighthouse scores)
• Final content migration and freeze
• QA across browsers and devices
• DNS switch + launch
