EveLens is a ground-up rebuild of EVEMon on a modern framework — .NET 8 and Avalonia, replacing the original WinForms architecture. Same soul, completely new foundation.
This has been months of work. Late nights, weekends, rabbit holes that turned into architectural overhauls. What started as wanting to fix a crash bug turned into rewriting the event system, which turned into splitting the entire codebase apart, which turned into replacing the UI framework entirely, which turned into… well, EveLens. Every piece I touched revealed the next thing that needed fixing. I lost count of the hours somewhere around the second month.
For anyone who’s relied on EVEMon over the years — this is that tool rebuilt for where EVE is now. And it’s current - the latest build includes all new skills and data from the March 19th update.
Character planning comes to Mac and Linux
For 20 years, character planning meant Windows. That’s done. EveLens runs natively on Windows, macOS, and Linux — same experience everywhere. If you’ve been playing EVE through Proton on Linux or on a Mac and had no character planner, this is for you. I spent a lot of time making sure it wasn’t just “technically works on Linux” — it’s native, it respects your OS conventions, it just works.
Not just dark mode — a full theme system
This isn’t a dark skin slapped on top of a light app. The entire UI was designed dark-first with a complete design system built around EVE’s factions. Six themes, each with its own aesthetic identity: Dark Space, Caldari Blue, Amarr Gold, Minmatar Rust, Gallente Green, and Midnight. Pick the one that fits how you play. This alone took weeks to get right — every theme had to feel like it belonged in New Eden, not like a color picker accident.
ESI scope control
This was one of the most requested features I kept seeing and it’s finally here. You decide what data you share. Use your own ESI keys and pick exactly which scopes are requested — Full, Standard, Skill Planner Only, or fully custom per feature group. Don’t want EveLens reading your mail? Turn it off. When you re-authenticate with fewer scopes, EveLens automatically clears data it no longer has permission to access. Your data, your rules.
Built natively for scale
This is the one I’m most proud of. Old EVEMon would slow down, cascade, or crash as you added characters. EveLens was architected from day one to handle as many characters as you throw at it. 100+ characters with smart batch scheduling, cache-expiry driven polling, and zero cascading slowdowns. The entire ESI scheduler was rewritten from scratch — priority queues, per-character rate limiting, phased cold start. If you’re running 20, 40, 60 characters, this is where you’ll feel it. I had a tester with 60+ characters hammering it for weeks and that feedback shaped everything.
Some ScreenShots Below of the new tool!
Also in the box
-
Skill planner with attribute optimizer — plan your queue, optimize remaps, see real training times. The optimizer runs every valid attribute combination and shows you the fastest path.
-
Privacy mode — hide and mask data for streaming.
-
Smart scheduling — zero wasted API calls.
-
Up to date with March 19th game data — all new skills included.
Migrating from EVEMon?
Skill plans, settings, and character config transfer automatically on first launch. Just install and open it. Though I would recommend you start over as it will be much better and richer expereince.
The build story
I wrote a 10-part engineering series documenting the entire journey — from the first crash bug to shipping a cross-platform application. Every number is from the actual code. If you’re curious what it looks like when one thread pulls another until you’ve rebuilt the whole thing:

I’ve put everything I have into making it solid, but there will be rough edges. Bug reports and feature requests are genuinely the most valuable thing you can give me right now. File them on GitHub or just reply here — I read everything.
