EVE Online Fitting Tool (Pyfa)

The tool models EVE Online ship fits using Pyfa-like logic to compute viability and performance across module selections. It targets pilots, fleet planners, and fit engineers who need quick validation and comparison during ship design, practice fleets, or when iterating on fits in real time.
Core logic aggregates ship base stats with module, rig, and implant effects, enforcing slot counts, faction/meta constraints, and power/CPU budgets. It exposes required features such as exact slot accounting, total power grid and CPU usage, cap stability estimation, DPS, and EHP calculations, with advanced options for rig bonuses, implant effects, and export-ready snapshots.
Outputs include total Power Grid (MW), total CPU (TF), capacitor fraction, DPS, EHP, range, and a structured fit summary, enabling quick validation and comparison between alternative fits. The algorithm tallies contributions from each module, applies bonuses, and checks viability against constraints. Error handling clearly indicates missing ship data, unknown modules, or slot/budget violations. Industry standards follow EVE units; localization is initially English, with potential expansion. Assumptions include static ship/module stats and optional implants; market data and real-time availability are outside scope. Exclusions: UI concerns, pricing dynamics, or in-game automation integrations.
