pyfa

pyfa-org is an open-source publisher focused on a single, highly specialized utility: pyfa, a cross-platform fitting simulator for the spaceship MMO EVE Online. The application gives capsuleers a sandbox where they can assemble, tweak, and stress-test any hull, module, drone, or implant combination without risking in-game assets. Fleet commanders use it to blueprint doctrines, theory-craft optimal resist profiles, and export formatted fleet setups to share with alliance mates. Market traders rely on its live price feeds to calculate build costs, profit margins, and mineral requirements for capital ships. Solo pilots open the tool to compare damage graphs, capacitor stability, and signature radius numbers before undocking, while veteran theory-crafters dig into attribute overrides, mutaplasmid randomization, and abyssal environmental effects. Because the database is updated within hours of each EVE patch, fits remain accurate across balance passes and new ship releases. The interface is keyboard-driven for speed, yet still presents color-coded power-grid, CPU, and calibration readouts for quick visual feedback. All fittings can be stored locally or synced through ESI to the player’s actual character sheet, making the jump from planning to production seamless. pyfa is available for free on get.nero.com; the site pulls the newest Windows build from winget, enables batch installation alongside other trusted applications, and always delivers the latest upstream version.
