Side Projects FN Sprite Tracker
App Live ⚡ Built with AI fnsprites.vercel.app

Built the tracker
I couldn’t find.

Every Fortnite sprite tracker I tried was buried in ads, didn’t save progress persistently, or had UX that didn’t match how collectors actually think. So I built one overnight — with Claude Code and Cursor — that does exactly what I need and nothing more.

The Problem

Every tracker
I tried annoyed me.

I collect Fortnite sprites. There are a lot of them — 8 themes, 4 rarities, dozens of characters — and tracking what you own gets complicated fast. The apps that existed either drowned you in ads, didn’t save your progress between sessions, or had filtering that didn’t match how collectors actually navigate their collections.

I’d open one, try to log what I had, get frustrated by the UX, and close it. That’s the worst outcome for a utility app — the experience getting in the way of the task.

The real gap
Every existing option made me do work for the app. I wanted an app that did work for me — showing progress, tracking completions, surfacing what was left, and telling me how close I was to finishing a theme.

“I built this the same night I got frustrated. That’s the right moment to ship a tool — when the problem is immediate and specific.”

What It Does

A tracker that
actually tracks.

📊
Collection + Mastery progress
Two live progress bars — how many sprites you own vs. how many you’ve mastered. Updates instantly as you check things off.
🎯
Rarity & theme breakdown
Visual ring charts by rarity (Rare, Epic, Legendary, Mythic) and progress by theme. Contextual nudge: “2 away from completing Rare.”
🔍
Filter, search & sort
Filter by theme, filter by rarity, search by name, group by character or theme, sort by completion or rarity. Find anything instantly.
🔗
Shareable collection link
Save your gamertag, get a public URL. Share in Discord, post it, use it to coordinate trades.
🔄
Trading
Mark sprites for trade or wanted, then find matches with other collectors. Built for the community that actually trades.
💾
Persistent saves
Your collection stays saved. This was the baseline every other app missed.

How It Was Built

One evening.
Claude Code and Cursor.

I didn’t plan this in advance. I got frustrated with existing apps, opened Claude Code, described what I needed, and started building. Idea to deployed — same night.

This is the workflow I’ve been developing: use AI to collapse the gap between design intent and shipped product. Claude Code handled architecture and feature scaffolding. Cursor let me iterate fast with AI-assisted edits. The design decisions — UX hierarchy, information density, what to surface first — came from my background as a product designer.

“This is what AI-augmented design looks like in practice. Not using AI to design — using it to remove the friction between a design idea and a working product.”

Hour 0
Problem definition
Frustrated with every existing tracker. Opened Claude Code and described the exact app I needed — sprite tracking by theme and rarity, persistent saves, shareable links, no ads.
Claude Code
Hour 1
Architecture + data model
Scaffolded app structure, sprite data schema, and storage model. Reviewed the output, directed the UX hierarchy, iterated on the layout structure in Cursor.

Hours 2–3
Core features built
Collection + Mastery tracking, progress bars, rarity/theme breakdown with ring charts, filter + search, owned/mastered states. Each feature iterated in Cursor with AI-assisted edits.
CursorGitHub
Hour 4
Trading + sharing features
Gamertag save, public collection link generation, trade matching. The shareable URL UX needed the most iteration — had to be obvious without being intrusive.
Cursor
Hour 5
Deploy to production
Pushed to GitHub, connected to Vercel, live at fnsprites.vercel.app the same night. Shipped it.
