Overview
Thrive Engine is a daily-planning app that brings training, nutrition, recovery, and scheduling into a single dashboard. Instead of auto-generating a schedule, every calendar item, a workout, a meal, a sleep window, is added by hand for one exact date or a set of repeating weekdays, so the calendar always reflects what you actually intend to do rather than a template's guess. The Today screen pulls live recovery, sleep, and strain data from WHOOP and displays it alongside the day's schedule and a completion grade, with Day, Week, and Month calendar views for zooming out, plus a built-in AI assistant to help reason about the plan. Under the hood it's an npm-workspaces monorepo: a Next.js app that serves both the UI and the REST API, and a framework-free shared package holding every rule, type, and the typed API client, built so the same logic could power a native app later without a rewrite. It's deployed on Vercel with a hosted Supabase backend (Postgres + Auth + row-level security), and WHOOP sync runs on-demand since Vercel's Hobby plan doesn't support the cron jobs a background sync would need.
