# StellarisDB

> Stellaris reference read from the installed game's own files, Cygnus v4.5.2 (9776) (Steam build 25664273, 2026-10-23). Every page states the version it shows; numbers name their source folder; our own conclusions name their formula.

## Tools that answer as text

The interactive tools compute in the browser; put /calc in front of a tool address and its query to get the answer as plain text (format=json for JSON). Names work instead of the game's keys.
- https://stellarisdb.com/calc/empire-builder — Empire builder check: Whether ethics, authority, civics, origin, species class and traits go together by the game's own rules, and what breaks if not. Parameters: e (ethics, joined by dots (keys or names: ethic_fanatic_materialist or Fanatic Materialist)); a (authority (auth_democratic or Democratic)); c (civics, joined by dots); o (origin (origin_default or Prosperous Unification)); s (species class (HUM, MAM, MACHINE…) or its name); t (species traits, joined by dots); n (1 for a nomadic empire). Example: https://stellarisdb.com/calc/empire-builder?e=Fanatic%20Materialist.Xenophile&a=Democratic&c=Technocracy.Meritocracy&o=Prosperous%20Unification&s=HUM&t=Intelligent.Natural%20Engineers
- https://stellarisdb.com/calc/ship-designer — Ship design totals: A ship design's hull, armor, shields, evasion, speed, power, damage a day, cost and upkeep from the game files (base values), and whether every slot and the power add up. Parameters: s (ship size (corvette, destroyer, cruiser, battleship, titan… key or name)); x (sections in slot order, joined by dots (keys or names: CORVETTE_MID_S3 or Interceptor)); w (weapons in slot order, joined by dots; - leaves a slot empty (SMALL_MASS_DRIVER_1 or Small Mass Driver)); u (utilities in slot order, joined by dots); r (core parts (reactor, FTL, thrusters, sensors, combat computer), joined by dots; left out = the starting parts). Example: https://stellarisdb.com/calc/ship-designer?s=corvette&x=Interceptor&w=Small%20Mass%20Driver.Small%20Mass%20Driver.Small%20Red%20Laser&u=Small%20Nanocomposite%20Armor.Small%20Nanocomposite%20Armor.Small%20Deflector
- https://stellarisdb.com/calc/tech-tree — Research path to a technology: Every technology needed before one, in research order, with each base cost and the total. Parameters: t (the technology (key tech_jump_drive_1 or name Jump Drive)). Example: https://stellarisdb.com/calc/tech-tree?t=Psionic%20Theory
