A fan-made Fortnite sprite tracker — track every sprite across all of its
finishes (Normal, Gold, Gummy, Galaxy, Gem, Holofoil, Cube, Quack,
and the Season 4 Cheat Master & Loot Hacker), see your collection
and mastery progress, save it to the cloud, add friends and compare or trade-match
with them, browse the live Item Shop, and look up any player's Battle Royale stats.

Chapter 7 Season 4 "Override" (update v42.40, Oct 15 — the Honey & One Wish
Willow Sprites) — 280 released variants across two generations: the Season 3
"Runners" roster (kept forever in the Sprite Garden) and the live Override
generation (27 Sprites — Sonic, Shadow, Jonesy, Klombo, the Fortnitemares set
Vampire / Spooky Dash / The Deer / Dumpster Dive, Morgana & Birthday, the
Honey & One Wish Willow wave-2 pair, Crash Bandicoot, Blinky, Pond and more) — in
Normal, Gold, Cheat Master, Loot Hacker, Bounty Hunter (live roster-wide Sep 24) &
Trick-or-Treat (live Oct 8). Epic confirmed Sprites are
kept forever, but a new generation takes over Battle Royale each season: older
-gen Sprites are preserved and displayed (Sprite Garden + Collection) rather than
used in BR ("may return down the line"), and Sprite Dust & Gizmos reset at the
flip. Season 4 also adds Hack the Lobby codes, Loot Hacks (spend Sprite Dust
to customise your chest loot), and a social Sprite Garden island. Leaked/
unconfirmed content (upcoming Sprites, unannounced codes, exact event times) is
flagged Rumored / Upcoming until confirmed.

Features
Accurate roster — every released sprite & variant, current through the
v42.40 (Oct 15) Honey & One Wish Willow drop (52 sprites / 280 released variants).
The current generation, Chapter 7 Season 4 "Override," is live (27 Sprites):
Sonic, Tails, Shadow, Jazz Jackrabbit, Klombo, Bush Ranger, Crown, Jonesy, 8-Bit
Blaster, Killswitch, Adventure, Storm Scout, Overshield, Mega Man, the Design-a-Sprite
winners X-Ray & Onigiri, the Fortnitemares set Vampire / Spooky Dash / The Deer /
Dumpster Dive, Morgana & Birthday, Crash Bandicoot, Blinky, Pond, and the
wave-2 Honey & One Wish Willow (Mythic) — in Normal, Gold, Cheat Master,
Loot Hacker, Bounty Hunter (live roster-wide Sep 24) & the Trick-or-Treat
Fortnitemares finish (live Oct 8). The Season 3
"Runners" roster (the full Gem line, Cube, Holofoil & Quack, Ironmouse back from
the vault, every Zero Point finish) is kept forever in the Sprite Garden.
Still-datamined Sprites (Meowscles, Squibbly, Cube, Head Shot, Bullet) are previewed
as Upcoming/Rumored so leaks never read as fact — each news item shows its source
and whether it's official.
🌱 Sprite Garden — the in-game social island where every Sprite you've collected
lives on, even past-generation ones retired from Battle Royale. Covered by a dedicated
SEO explainer at /sprite-garden. (The earlier in-app Community Gallery / Layout
Planner were retired — they saw no real use — leaving the Garden as an in-game feature
the tracker documents rather than reimplements.)
🔓 Lobby Hacks — the season's Hack the Lobby / Admin Panel codes as a
first-class tab and a canonical /codes page: grouped by reward, per-code copy,
redeemed-tracking, a "new this week" highlight + verified dates, and upcoming
codes shown before their string drops.
Guides (SEO) — prerendered explainers competitors don't have: Sprite Garden
(/sprite-garden), Sprite Dust & Loot Hacks (/sprite-dust), Events schedule
(/events) and the Tier list (/tier-list), each with FAQ/HowTo structured data.
Upcoming & leaked — a card that lists every unreleased/datamined sprite
sorted by its leaked release date, with a live (“in 8 days”),
tap-to-open. All clearly badged .
Changelog
Release notes — technical, but written for humans, with the reasoning behind the
bigger decisions — live in CHANGELOG.md and in-app via the
Changelog link in the footer (src/data/changelog.js). Keep the two in sync
when shipping.
Some variant art (Holofoil, Air & Seven) uses AI (Google Gemini) renders where
no official image was available; real-person collab sprites (Vini Jr., Pollo)
use Epic's official art with the background removed — never an AI likeness.
Other missing images fall back to a built-in SVG generator
News & events via official Fortnite patch notes,
Epic communities &
fortnite-api.com; some event details
cross-referenced from community trackers
(Vice, Beebom,
AllThings.How, Hotspawn,
) — each event links to and labels
its source (official vs unofficial)
No game assets beyond the identification sprite images are bundled.
Tech
React 19 + Vite + Tailwind CSS
Supabase — auth (email + Google OAuth) and storage
(Postgres + Row Level Security + RPC functions)
Google Gemini for AI-reskinned variant art; Canvas API for image exports; PWA
(manifest + service worker)
Development
npm install
npm run dev # start dev server
npm run build # production build
npm run lint # lint
Supabase configuration
The app ships with the project's public Supabase URL + publishable (anon) key
baked into src/lib/supabase.js. Those keys are safe to expose in the client —
all data access is protected by Row Level Security. To point at a different
project, set VITE_SUPABASE_URL and VITE_SUPABASE_ANON_KEY (see .env).
Player stats proxy
The Player Stats tab calls a serverless function (api/stats.js, deployed on
Vercel) that forwards to fortnite-api.com with an API
key. Set FORTNITE_API_KEY in the Vercel project's Environment Variables — it is
a server-only var (no VITE_ prefix) so it never reaches the client bundle.
The Item Shop and Cosmetics tabs use fortnite-api.com's free, no-auth endpoints
directly and need no key.
Database schema (applied via migrations):
profiles — one row per user (gamertag, is_public, epic_username,
epic_platform, showcase_sprite_ids, stats_public, discord,
notify_trades, …). Public-readable for
sharing; owner-writable. Shared-link reads go through the get_shared_profile()security-definer RPC, which returns only public display fields plus the Epic
account only when stats_public is on. Anonymous SELECT on the Epic columns
is revoked at the DB level, so epic_username is never exposed unless the owner
opts into public stats.
sprite_progress — (user_id, sprite_id) with owned / mastered flags plus
for_trade / wanted (which power the Friends → Trade matches view — flag a
spare or a want and the matcher pairs you with your friends).
Readable when the owning profile is public (or it's your own); owner-writable.
friends — (user_id, friend_id), RLS so you only ever see/manage your own
rows (a one-directional "save to compare" model — no reciprocal consent).
trade_confirmations — (confirmer_id, partner_id); each side marks a completed
trade. Both directions present ⇒ a mutual trade. RLS: involved parties read,
confirmer deletes; inserts go only through trade_confirm(uuid).
trade_vouches — (voucher_id, vouchee_id, note). A vouch only records via the
gated vouch_add(uuid, text) RPC (there is no direct-insert policy), which now
requires a mutual trade confirmation (Phase 2 gate), a public target, no self,
and ≤5/24h.
trade_reports — (reporter_id, subject_id, reason), private to the reporter
(RLS, no public read); recorded via report_add(uuid, text). Advisory only — never
auto-adjusts reputation.
bug_reports — insert-only feedback backup.
Key RPCs (all security-definer, public profiles only, so raw collections are never
exposed): leaderboard; my_friends() — your saved friends with the same Flex Score;
friend_trade_matches() — two-way trade matches limited to your friends (gamertag +
discord, they_give, i_give); search_public_profiles(text) — gamertag search to
add friends; find_trade_matches(uuid) — the global (all public players) variant;
sprite_ownership_stats() — privacy-safe aggregate ownership counts. Reputation:trade_confirm / trade_unconfirm / trade_confirmations_for (trade confirmations),
vouch_add (mutual-trade-gated), vouchers_for(uuid) (credible voucher list), and
trade_reputation_batch(uuid[]) — returns each player's credible-voucher count + tier
(🤝 Trusted / ✅ Verified / ⭐ Top), where Verified/Top require non-mutual vouchers
(collusion capping: reciprocal back-vouches can't inflate the top tiers).
(Some older tables are kept in place, non-destructively but unused by the app: the
legacy trade_posts board (the current Trade tab uses lightweight
for_trade/wanted matching instead of posts) and the old crowd-sourced map —
maps, map_shares, map_markers, map_marker_votes.)
Customizing
Sprite types and which themes each one has: src/data/sprites.js
(sprite_ids are derived as ${typeId}_${themeId}).
Track ownership, levels & mastery — mark a variant owned, then set its
level 1–5 (level 5 = mastered) right on the grid card or in the detail
view, with a Lv 3/5 readout. Works instantly as a guest (saved in your
browser) and syncs to the cloud when you log in, with a live save-status
indicator. Bulk quick-add: filter to a theme or rarity and mark the whole
shown set owned in one tap.
Import from a screenshot — snap your in-game sprite locker and on-device
OCR (Tesseract.js, running entirely in your browser) pre-checks what it
recognizes; review and mark them owned in one go. The image never leaves your
device.
Next to chase (action plan) — reads your own collection and live data to
surface what to do right now: farm a finish while a Power Hours is boosting it,
claim the free Cheat Master Sprites whose lobby codes are live, grab live Dust
codes — then your rarest missing sprite, the set you're closest to finishing,
and an easy one to grab.
Printable checklist — a one-tap, ink-friendly one-page checklist of every released
Sprite and the finishes it comes in, with your owned ✓ / mastered ★ progress filled
in, to print or save as a PDF.
Dust planner — type your Sprite Dust balance and see which rarities and finishes
you can afford to (re)summon against the current cost table, plus how many of your
owned variants are within budget.
Drop rates per sprite (community-datamined estimates; Epic publishes none).
Chest luck calculator — turns a drop rate into real expectations: average
chests to find a sprite, chests for a 50/90/99% chance, and a live "open N
chests → chance of at least one."
Per-sprite pages (/sprite/<name>, e.g. /sprite/grim-reaper) and an
all-sprites index (/sprites) — static, SEO-friendly pages with drop rate,
Dust cost, chest odds, ability, variants and an FAQ, prerendered at build time
from the same data the app uses (scripts/prerender.mjs), with JSON-LD for
rich search results.
Sprite detail view — rarity, drop rate, ability, a gameplay tier
(S/A/B/C — how strong it is, not just how rare), how the ability scales
to Lv 5 (e.g. Demon lifesteal ≈10→≈30 HP; it highlights the level you own),
and every variant with its in-game bonus (e.g. Gummy = +10% Sprite Dust).
Leaderboard & Flex Score — a rarity-weighted ranking of public
collections, plus a compare view (what you both have / each are missing).
Friends — save any player (gamertag search, ★ on the leaderboard, or the
"Add friend" button on a shared collection), see them ranked by the same Flex
Score, and compare in one tap. A Trade matches view lines up your spares
(for_trade) against a friend's wanted list (and vice-versa) and flags two-way
matches, with their Discord to coordinate. Backed by RLS + security-definer RPCs
(my_friends, friend_trade_matches, search_public_profiles) so a private
friend's collection is never exposed.
Loot Hacks tracker — the current rotating Loot Hack weapons you buy with
Sprite Dust to bias your chest loot, with a next-refresh countdown card and a
/loot-hacks guide page; refreshed each rotation.
Community ownership — each released Sprite shows "owned by X% of collectors"
(and mastered by Y%), from privacy-safe aggregate counts (sprite_ownership_stats
RPC), baked into the per-Sprite SEO pages too.
Player Stats — look up any player's Battle Royale stats by Epic display
name (or PSN/Xbox): wins, win rate, K/D, kills, matches, top-10/25, hours, and a
solo/duo/squad breakdown. Requires the target's match history to be public. The
stats API key is held server-side by a small serverless proxy (api/stats.js),
never shipped to the browser. Connect your account: signed-in players can
save their Epic name in their Profile (or via a one-tap "save to profile" on any
result), and the Stats tab then auto-loads their stats on open.
Item Shop — today's rotating Fortnite Item Shop (the in-game store, shown
read-only) grouped by section, with item art, rarity and V-Bucks prices, plus
filters (search, rarity, type, price sort). Tap any offer for a detail view
— big render, description, set/series/season, shop history, and every item
bundled in the offer. Pulls live from the free public
fortnite-api.com.
News & events — a feed that auto-detects Fortnite's current live build,
alongside a curated events layer (Gold/Gem/Shiny Hours, New Sprite Day, weekly
Mastery Mondays / Power Hours), summarised on the /events schedule page.
Every item shows
its source and whether it's official (Epic) or unofficial (with a
Tentative badge for unconfirmed dates), and live events pin to the top. A
dismissible announcement bar highlights the current featured event.
Profile page — manage your gamertag, public/private visibility, sign out,
and delete your data.
Trainer Card — your shared link (?u=<your-id>) opens a player profile:
an avatar and up to 6 hand-picked showcase sprites, headline stats, and
earned badges (Completionist, Shiny Hunter, Mythic Owner, Variant Hunter…)
derived on the fly from your progress. Badges also appear on the leaderboard.
Optionally (opt-in in Profile) surface your live Battle Royale stats on the
card too.
Share & export — set your gamertag and share the read-only public link
above; copy a ready-to-paste Discord/Reddit caption of your progress; or
export a Sprite Locker–style poster of your collection (or just the sprites
you still need).
Filter, search & group — by theme, rarity, ownership; hide mastered, show
unreleased; group by theme / rarity / tier (a built-in tier list) / sprite.
On every screen the filters tuck behind a single Filters button (search &
sort stay out for quick access), so the sprite grid leads.
Progress & breakdown — overall Collection % and Mastery %, per-rarity and
per-theme breakdown, and completion badges.
How Sprites work — an in-app guide to the parts players get caught out by:
extraction (extract or lose it), leveling & Mastery Mondays, mastery, and
variants. Reachable from the ⋯ More menu, the footer, and a small card above
"Next to chase" once you sign in.
Backup & restore — guests can copy a backup code to move progress between
devices; restoring merges (never wipes). Logged-in progress auto-syncs.
Fast & installable — a PWA (works offline), with heavy views
code-split for a quick first load and privacy-friendly, cookieless analytics.
Google sign-in + email auth.
