pyfa for Mac

What pyfa does for EVE Online pilots

pyfa (Python Fitting Assistant) is a free, stand-alone application that helps EVE Online players design and evaluate ship fits outside the game client. It lets you assemble loadouts, compare module choices, and tweak configurations to match specific roles or tactics, so you can plan fittings with confidence before flying them in-space.

Core capabilities

• Export and import fittings quickly between pyfa and other tools or shareable formats.
• Run compatibility checks to ensure modules, rigs, and subsystems work together on a given hull.
• Produce detailed performance breakdowns (tank, DPS, range, capacitor, speed) to quantify trade-offs.
• Support a wide variety of hulls, modules, and subsystem combinations across multiple factions.
• Maintain an updatable local database so the tool reflects the latest mechanics and items.
• Friendly, approachable user interface designed for both newcomers and seasoned fitters.

Who benefits most

• New players who want a safe environment to experiment with modules without risking in-game ISK.
• Experienced pilots who need to iterate on meta fits, run theoretical comparisons, or share optimized setups.
• Corporations and fleets looking to standardize fits or prepare doctrine packages.

Maintenance and data updates

pyfa keeps its data current through periodic updates, so weapon stats, module attributes, and balance changes are reflected shortly after they appear in the game. The program also allows users to manage the local database, apply patches, or load custom item definitions when needed.

Alternatives worth considering

• CheatSheet — a free, lightweight reference app for quick module and skill lookups.
• Eve Workbench / In-client fitting tools — options that integrate directly with EVE or offer browser-based fitting features.
