This page should be updated due to game changes.
Reason: PYFA version updates/UI changes and possible game damage profile updates.

PYFA (Python Fitting Assistant) is a cross-platform fitting application that can be used natively on any platform where python and wxwidgets are available, including Windows, Mac and Linux.

It provides many advanced features such as graphs and full calculations of any possible combination of modules, fits, etc.

To download PYFA go to this page or run Winget install pyfa

Initial Setup

Linking Your Characters

To connect your EVE character to PYFA you will need to use CCP's ESI SSO.

To do this:

  1. Open the SSO Character Management screen (Character -> Manage ESI Characters).
  2. Create a new character by clicking Add Character.
  3. A page will open in your default browser - sign in using your EVE Online account credentials.
  4. Select the correct character from the list.
  5. Click Authorise.

If you are using a Mac, Mac OS security prevents the redirect back to the local server. In order to authenticate your characters, you'll need to manually copy your token.

To do this:

  1. Open the Pyfa Preferences window (Pyfa -> Preferences).
  2. Click on the EVE SSO tab.
  3. In the Local Authentication section, choose Manual rather than Local Server
  4. Dismiss the Preferences window
  5. Open the SSO Character Management screen (Character -> Manage ESI Characters).
  6. Create a new character by clicking Add Character.
  7. A page will open in your default browser - sign in using your EVE Online account credentials.
  8. Select the correct character from the list.
  9. Click Authorize.
  10. The web browser will redirect to a page that says "Please copy and paste the token below into pyfa.""
  11. Copy the ESI token from the web page
  12. Switch back to Pyfa, paste the token into the SSO Login box and click OK. You might not see this box because it launches underneath the SSO Character Management window. Simply drag the SSO Character management window out of the way and you should now see the SSO login box.


You should change your settings to match the images below. General settings are mostly personal preference, however the network settings are required for PYFA to query EVE-Central for prices.

To change settings go to Global -> Preferences or press Ctrl - P.

Damage Profiles

Copy the following into the damage pattern editor by selecting all the damage patterns, and copy them into your clipboard. Then inside of PYFA under the editors tab select the damage pattern editor. You will be prompted to name your new profile, hit OK. At the bottom right hand side there will be 2 buttons. Select the one that says import from clipboard. From now on you will be able to select the type of incoming damage and you can change your fit accordingly. (The Law damage profile is CONCORD Response.)

Adding Fleet Boosts

You can set a Squad/Wing/Fleet booster in PYFA, each role can have a different character and ship assigned to it. To set boosts you first need to create a boost ship, this could either be an empty ship (to apply character skills only) or a boosting ship (to apply module boosts). Once you have created a boost ship right click the fit and tick booster fit. Ships assigned as boosters are marked with Boost set.PNG. You can also drag fits in to the boost window and use the right click menu to set a Squad/Wing/Fleet booster.


When you have a boost ship set you then open up the Fleet tab under the Additions (4) pane. you can select boost ships from the drop down box and any character can be used.

Importing/Exporting Fits

Importing fits

PYFA can import fittings directly from clipboard, to import a fit either go Edit -> From Clipboard or Ctrl - V. To import a fit from EVE to PYFA simply click 'Copy to Clipboard' in game. Once you have a fit copied to clipboard you can paste it into PYFA.


Exporting fits

To export a fit either go Edit -> To clipboard or press Ctrl - C, and select your preferred format. The EFT format is the most widely used and can be imported into EVE by opening the fitting window in game, clicking browse and clicking 'Import from Clipboard'. The EFT format is commonly used on forums and to import fits for a variety of 3rd party programs.
