pyfa for Windows

Overview and purpose

Pyfa (Python Fitting Assistant) is a stand-alone fitting utility for EVE Online that lets pilots design, test, and archive ship fits outside the game. Built with Python and a wxWidgets-based interface, it provides an approachable environment to experiment with modules and loadouts so you can refine tactics before committing in-game.

Supported systems

Runs on Windows, macOS, and Linux.
Cross-platform compatibility makes it easy to move between workstations or collaborate with friends.
As an open project, community contributors help keep builds available for multiple operating systems.

Core capabilities

Simulate and evaluate different ship configurations without logging into EVE.
Store and recall saved fittings for future analysis and comparison.
Use a graphical interface to tweak modules and view statistics in real time.
Free and open-source, so anyone can download, inspect, and modify the codebase.

Benefits for players

Pyfa speeds up strategic planning by letting both new and veteran pilots fine-tune builds without spending in-game assets. It’s especially useful for iterating on fits, testing tradeoffs (tank vs. DPS vs. mobility), and preparing several options to suit different fleet roles.

Other fitting solutions and web-based fitters exist if you want a different workflow.
Note: “SHAREit” is sometimes mentioned alongside downloads; that app is a general file-transfer tool and not a fitting application.
For broader EVE utilities, look into skill planners and market tools that complement fitting software.

Quick start

Download the appropriate package for your operating system from the project’s release page.
Install and open the program; create a new fit and begin adding modules.
Save builds you want to compare and use the built-in statistics to evaluate performance.

If you want, tell me which OS you’re using and I can point you to the right download and a short installation walkthrough.
