What is this?

A fan-made collection tracker for Infinity Nikki — see your Eureka sets and variants at a glance, track your progress, and know exactly what you're still missing.

About me

I'm Julie Evans, a UX-focused developer. This tracker is a side project built with Next.js, Supabase, and MUI — born out of playing the game and wanting a clearer view of my own collection.

Features & Pages

Browse freely without an account, or sign in to save and track your own personal collection. Filtering, sorting, and views are available either way — obtained and missing filters unlock once you're signed in.

Eureka

Browse every Eureka set and its individual pieces in one place, mark pieces as obtained, and watch your progress update in real time.
  • Group by set or view pieces individually, and filter to a single Eureka set

  • Switch to a by-color view, or filter by a specific color

  • Filter by category and rarity, and sort newest or oldest first

  • When signed in, filter to only obtained or only missing pieces — plus a dedicated Missing view that lists everything you haven’t collected yet

  • Trials view — see how far along you are in each in-game trial

Outfits

Track full outfit sets along with their evolutions and glow-ups, and mark what you own.
  • Group by set or view variants individually, and filter to a single outfit set

  • Filter by evolution stage, or hide evolutions and glow-ups to focus on base sets

  • Filter by one or more outfit categories and by rarity

  • Adjust the display density and sort order, and when signed in filter to only obtained or only missing items

Seasons

Explore outfits by season — grouped by location, with each season’s categories and set counts at a glance.
  • Sort seasons newest or oldest first

  • Open any season to see its outfit sets grouped by category

Custom Looks (TBD)

Build and save your own outfit combinations from Eureka and outfit pieces.
  • Mix and match pieces into a saved look, with thumbnail previews

  • Save a few looks for free, or upgrade to premium for unlimited looks

Profile

Your collection at a glance once you’re signed in.
  • See completed Outfit Sets, Evolutions, Glow-ups, and Eureka Sets at a glance

  • Toggle between Outfit and Eureka stats — each with completion charts and your most recent updates

Settings

  • Appearance — choose a system, light, or dark mode, set a default sort order, and pick a color theme (additional themes with premium)

  • Profile — update your display name, username, and avatar

  • Account — change your email or password, request admin access, or delete your account
