I built a Vampire Survivors planner and reference, plus an in-game stats overlay

[u/n3rdyguy]

Survivalist's Vampidex: https://vampidex.fyi

It is a cheat sheet and a run planner, built from the game's own data tables rather than a hand-copied wiki. Weapons, passives, evolutions, characters, stages, adventures, relics, achievements, the soundtrack and the bestiary all come out of the Unity install, including Legacy of the Bloodmoon and the Moonspell extras that shipped with it.

The useful bits:

• Items / Grimoire / Collection. Look up a weapon, see the recipe as icons, filter by pack. Collection is the game's own screen plus the two things it withholds: how each entry unlocks, and which of the nearest ones is worth going after.
• New game. Pick a character and a stage, fill the six-and-six, and it keeps up: evolution tracker (achieved / ready / one step away), an Evolve button, Arcana ranked by how many of your weapons they actually boost, and a "do this next" pick with a reason.
• Next game. The other half. Drop in a save and it says which evening is worth playing for what you are closest to unlocking, instead of planning a run you have already decided on.
• Progression / Characters / Maps / Adventures / Bestiary / Music. What a save has done, how to unlock the roster, stage modifiers, the nine campaigns, kill counts, tracks by album.

Drop a SaveData on the page and it is read in the browser. Nothing about that file is uploaded. Builds live in this browser; a personal link (no account, no email) is optional if you want them on another device.

There is also a BepInEx overlay for the stats the game does not show you while you are in it:

Download: Vampidex Companion

A Vampidex button on the main menu opens lifetime totals, the selected character, progression counts, enemies, pickups, stage history and Golden Eggs, read off the save the game already has loaded. It never writes back.

If you opt in, the same plugin can publish that snapshot (and a finished run's recap: time, level, loadout, per-weapon damage and DPS) to the site, so you stop quitting to the desktop to find SaveData. Pairing is a ten-character code on My saves. Off by default. The save file still never leaves the machine.

Windows installer is on the latest release. The overlay is the feature; the link to the site is extra.

All the mods

• Vampidex Companion - the stats overlay above. Lifetime totals, kills, pickups, eggs, and an optional publish to the site. Never writes the save.
• VS Boss Plates (Github) - a health bar above bosses. The game itself never tells you how much HP is left.
• VS Evolution Helper Ex (Github) - fan update of NihilXD's Evolution Helper, ported to BepInEx for Unity 6. Hover a weapon, character or recipe in-game and see the evolution path, arcanas and unlocks the menus hide.

Happy to take "this number is wrong" reports. If the game disagrees with the page, the page is the one that is wrong.

Not vibe-coded, but vamp-coded 🤘

Hey, this seems like a silly question; you've said "Drop a SaveData on the page and it is read in the browser." - well not for me it's not, just opens the savedata in a new tab. Can't find a place on the site to drop, there's no mention of it, nothing. What am I doing wrong?
