EVE Technology and Research Center Third Party Developers

Hello All,

I’m Alia Collins, and I am maintaing my own EveMon fork. I am building this independently.

EVEMon is back and fully working. Rebuilt from the ground up on .NET 8.

What’s New in v5.1.0:

  • Migrated to .NET 8 - Modern framework, better performance, proper connection handling

  • ESI Best Practices - Proper rate limiting, caching, and error handling so your requests don’t get blocked

  • Catalyst Expansion SDE - All game data updated (December 2025)

  • Booster Simulation - See how boosters affect your training time in attribute optimizer

  • Better Status Bar - Shows exactly which API is refreshing next (e.g., “Skills: 00:02:45”)

  • New UI Experiments - Check out the About window (Help → About) for a preview of where the UI is heading

  • Auto-Update Notifications - EVEMon now checks for updates from the new repo

Stability Note: This is a major rebuild. Everything worked fine in my testing, but please expect some stability issues as we shake things out. Report anything you find.

Beta Channel: There’s also a rolling beta release for those who want the latest features. Expect high velocity updates as I get more time to work on this.

Download, extract, run. No installer.

Latest Stable: Release EVEMon v5.1.1 · aliacollins/evemon · GitHub
GitHub: GitHub - aliacollins/evemon: EVEMon - EVE Online character monitoring tool (.NET 8 fork)

Changelog:

v5.1.1 (Jan 5, 2026)

  • Fixed: Settings now save correctly between restarts
  • Fixed: Update notifications now work properly
  • Deprecated: Certificate Browser (use Ship Browser for Masteries)

Note: If you downloaded v5.1.0 earlier, please manually update - the update notification system was broken in that version.

NOTE: - There are more than one EveMon forks out there. My fork focuses on high speed release cadence, taking your suggestions and features and seeing how it can be quickly integrated into EveMon. The current active community maintained fork is - GitHub - mgoeppner/evemon: A lightweight, easy-to-use standalone Windows application designed to assist you in keeping track of your EVE Online character progression.

hey!

I’ve been keeping evemon alive for the last few years! Currently I have been waiting on steve to update his SDE conversion, but I have another option for the conversion which i havent had the chance to get to yet due to an irl injury.

Feel free to contribute back PRs!

Having some issues with this, I unisntalled my previous evemon and run this, i fire it up and get this message, i dont know why as i put the new evemon stuff in a new folder. I go on to open evemon and non of my ESI keys are there even though i added them all yesterday , gone back to 4.2.2. which works for me (althuogh the certificate option in it are incorrect)

Having the same problem, it seems to be stuck with this.

Gonna go back to the old one until it looks like it fixed.

I have uninstalled my old Evemon instance, cleaned the registry, etc. Then I installed your ver 5.1.1. Unfortunately, it shows unknown skills from the most recent update. I have also tried your beta version with no luck.

Thank you

Just in case you are not aware there is a recent reddit thread on r/Eve about your new release:

Stealing other people’s work without credit is bad actually. A study in AI slop and the “new” evemon fork

TL:DR: Roughly a week ago, Alia Collins released a version of EveMon as a fork of Peter Han’s original version to much fanfare. They claim to be reviving a dead project, however EveMon has been alive and maintained at here for some time now.

The issues with this are:

  • The new author is taking credit for work that isn’t theirs and is copied from the active fork
  • Removing the entire project history and attributions it contained
  • Using this work to ply for donations

Personally I don’t know the exact details to can make a proper elaboration who is right and what nuances are there to support either side, but it is irrelevant as well.

Just linking this so you can address the situation in case you aren’t aware of it yet as well as people can learn about it and do their own research regarding the subject and come to their own conclusions.

Hey, thanks for letting me know about this. I appreciate you keeping it neutral and letting people make up their own minds. I had missed this.

I originally downloaded the ZIP to my machine just to play around with it. I never expected to actually get it working, but it did, and I pushed it out. Beginner mistake, I didn’t realize downloading the ZIP instead of properly forking would strip the commit history.

In my mind, I had done the right thing made it available under GPL and credited Peter Han and the original EVEMon team. Technically not wrong, but I get the sentiment. The history has since been grafted back. You can check the Edit on the reddit post as well.

This drama has been following me since day one of the fork. I plan to keep updating it. If people use it, great. If they want to use other forks, that’s fine too.

There has been group of people have been relentlessly attacking me and pressuring me to push my code into the other fork. That’s not right either, If I want to maintain my own fork. Though it’s demotivating enough I hope to continue pushing out updates. Yes, I used AI to help ship faster. In today’s world, if people are against that, that’s fine too.

I’m not here for drama. I just want to make a tool that works. I’ll keep updating it, if people use it, awesome, hope people get something out of it.
