Stoxly
A stock portfolio tracker with Alpha Vantage market data, a fallback for API rate limits, and USD/NGN currency conversion.
Overview
Stoxly tracks a personal stock portfolio against live market data from Alpha Vantage.
The free API tier rate-limits hard, so the app falls back gracefully instead of breaking when the limit hits, and every value can be shown in US dollars or Nigerian naira.
Next.js 15 with Prisma on SQLite, shadcn/ui, and Recharts for the portfolio and market views. Built over two days.
