Pyfa: Your Best Fitting Friend

Let's talk about fitting ships. No specific ships, just fitting in general. Fitting is best done with a plan in mind; simply slapping modules onto your ship is inadvisable at best. The built-in fitting tool has a "simulation" mode to help with that! Activate it and you get a pretend-ship that you can put any modules on (whether you own them or not), planning your fit ahead of time. That's enough, right? Wrong.

Unfortunately, the built-in fitting tool is rudimentary at best, as it lacks numerous important aspects of planning your fit. Partial item searching, implants, boosters, inter-ship effects (like command bursts), and many other features are not part of the ship simulation. Especially in capsuleer-to-capsuleer combat, where every edge counts, that is simply insufficient. That is why I am here to pitch...


Pyfa (short for "Python fitting assistant") is a stand-alone 3rd party application dedicated to bringing you all the features you need to plan your perfect ship fit. It is free and open source software, meaning not only is it free to download, but its source code is fully public and you are free to modify it and redistribute it as you wish.  You can find the latest download on its releases page, with versions available for Windows, Mac, and Linux OS.

It is a pretty self-explanatory piece of software, but if you need it, Eve University has a guide for it as well. That's not why I'm here, though. I'm here to tell you to use it, because if you aren't, you're missing out.

Some examples of what you're missing out on:
  • Fit simulation with any combination of skills you want, either imported from a real character, or just made up ones (such as "All Level V", so you can feel inadequate)
  • Fit import/export using simple Ctrl+C/Ctrl+V
  • Reliable price estimates for common ships/modules 
  • Implant and booster simulation
  • Easily swap variants of modules to make shimmy those tight fits until they work
  •  Quickly change up all the ammo in your guns, to be prepared for any circumstance
  • Item search that takes into account abbreviations and other capsuleer jargon

  •  Damage application graphs

  • And much, much more...

Why are you promoting this? Who's paying you?

Nobody. I do, however, find it incredibly important that we, as a community, use the right tools for the job. When navigating the starless wastes of complex ship fitting, there is no reason to settle for the default laggy and limited ship simulation when a tool such as Pyfa is available. Plus, writing this post means I can use it as a reference for convincing new players to do themselves a favor.

Big thanks to Sable Blitzmann, who has maintained Pyfa for years, and continues to, in spite of no longer actually participating in flying spaceships around.


Side note: please disregard any post that showed up in your RSS feed regarding commentary on blingy/shiny ships; I was cleaning up old unused drafts and accidentally published that one without meaning to.


  1. I am Sable Blitzmann, and I approve of this message.

  2. Best part is I can install it at work from the ZIP (no installer) and theorycraft while I ... uh... "work".
