Character Intelligence for EVE Online

EveLens is a complete, ground-up rewrite of EVEMon -- the character planner EVE pilots relied on for nearly 20 years. What was once a Windows-only desktop app locked to legacy frameworks is now a modern, cross-platform tool built on .NET 8 and Avalonia UI, running natively on Windows, Linux, and macOS.

This isn't a patch or a fork update. It's 114,000 lines of WinForms reduced to 34,000 lines of modern code, with 1,857 tests, 14 architectural laws, and support for 100+ characters out of the box.

Download EveLens 1.3.0

The Windows installer is code-signed by a verified Certum certificate.

Download and run EveLens-stable-Setup.exe. The installer handles everything -- .NET runtime, shortcuts, auto-updates. The binary is code-signed, so Windows SmartScreen won't block it.

# Download the AppImage from the release page, then:
chmod +x EveLens-*-linux-x86_64.AppImage
./EveLens-*-linux-x86_64.AppImage

That's it. Single file, no install, no dependencies. Works on Ubuntu, Fedora, Arch, and most distros.

unzip EveLens-*-linux-x64.zip -d evelens
chmod +x evelens/EveLens
./evelens/EveLens

Requires .NET 8.0 Runtime installed.

1. Download EveLens-*-osx-arm64.app.zip from the release page
2. Extract the zip -- you'll get EveLens.app
3. Drag EveLens.app to your Applications folder
4. First launch -- important: macOS blocks unsigned apps. Open Terminal and run:

# Navigate to where you extracted EveLens.app, then run:
xattr -cr EveLens.app

This removes the macOS quarantine flag. Double-click to open normally after this.

Why is this needed? EveLens is code-signed on Windows but not yet on macOS (Apple requires a separate $99/year developer certificate). Without a macOS signature, Gatekeeper reports the app as "broken" rather than "unsigned", so the usual right-click Open workaround doesn't work. The xattr -cr command is the reliable fix. The app is safe -- it's open source and you can verify the code yourself.

unzip EveLens-*-osx-arm64.zip -d evelens
cd evelens

# Remove quarantine and set executable permission
xattr -cr .
chmod +x EveLens

# Run
./EveLens

Coming from EVEMon? We recommend a fresh start. EveLens is a complete rewrite -- your EVE characters are tied to your ESI tokens, not your old settings. Add your characters through the ESI login and you're good to go.

EveLens runs natively on Windows, Linux, and macOS from a single codebase. System tray, notifications, clipboard, and dialogs all use native platform APIs. Same features, same UI, same updates on every platform. No Wine, no workarounds.

Built from the ground up for scale. Smart batch scheduling, per-character circuit breakers, and staggered ESI polling mean 60, 80, or 100+ characters load fast and stay responsive. The old EVEMon collapsed at ~50 characters -- EveLens doesn't.

Six color palettes inspired by New Eden's empires. Every control respects the active theme with runtime switching.

• Dark Space (default) -- navy + gold
• Caldari Blue -- cool steel blues
• Amarr Gold -- warm golds and ambers
• Minmatar Rust -- earthy oranges
• Gallente Green -- teals and greens
• Midnight -- deep purples

You choose what data EveLens can access. Three presets (Full, Standard, Skill Planner Only) or custom selection from 16 feature categories. When you re-authenticate with fewer scopes, EveLens automatically detects revoked permissions, clears stale data, and deletes disk caches for those endpoints. Your data, your rules.

GPU-accelerated interactive visualization of EVE's ~400-skill tree rendered as a star constellation. Skills as stars, prerequisites as connecting lines, skill groups as colored nebula clusters. Zoom, pan, search, click-to-inspect. Trained skills glow, training skills pulse.

20+ data tabs per character: Skills, Skill Queue, Clones, Assets, Market Orders, Contracts, Industry Jobs, Wallet Journal, Wallet Transactions, Mail, Notifications, Kill Log, Planetary Industry, Research Points, Standings, Contacts, Employment History, Medals, Loyalty Points, Factional Warfare.

Multi-tab plan editor with integrated Skills, Ships, Items, and Blueprint browsers. Entry detail panel with prerequisite tracking and completion checkmarks. Attribute optimization and injector cost estimates.

Per-endpoint health state machine that tracks ESI reliability per character. Transient errors are silently retried. Persistent failures get one activity log entry, not a hundred. Recovery is automatic. No more error spam filling your notification bell.

Create shared skill templates for fleet doctrines, assign multiple characters, and compare training times side-by-side. Import from existing plans, see who can fly what, and generate personal training plans for each character with one click. Perfect for FCs managing fleet comps across 30+ characters.

Full Simplified Chinese (简体中文) localization with 300+ translated UI strings and 50,000+ CCP official SDE translations for skills, ships, items, and blueprints. Language picker in Settings → Appearance with auto-restart. Game terms use CCP's official Chinese translations.

Export your full skill list or training queue to CSV files for spreadsheets, fleet planning, or sharing with corpmates.

Compare up to 10 characters side-by-side. Skills are shown with color-coded level blocks so differences jump out immediately. Toggle to show only skills that differ across characters. Columns auto-size and show full character names.

A slider in Settings scales all text from 80% to 150%. Changes apply instantly as you drag -- no restart needed. Works across every window, dialog, and control in the app.

A clock icon in the status bar shows how many of your characters need training attention. Click to see everyone sorted by urgency -- empty queues at the top, healthy at the bottom. Click any name to jump to their Queue tab. Scrollable for large fleets.

• Clone tracking -- jump clone locations, implants, and jump cooldown timer (respects Infomorph Synchronizing skill)
• Native OS notifications -- skill completions via your system's notification center
• Activity center -- bell icon with 200-entry event log, smart noise filtering
• Character groups -- organize characters by purpose with colored tags and custom ordering
• Balance change indicator -- real-time ISK delta with directional arrows
• Auto-update -- Velopack-powered updates with delta downloads, checks in the background
• Data cache -- near-instant tab loading, limited offline viewing
• Per-character endpoint manager -- toggle individual ESI endpoints on/off
• Privacy mode -- for streamers and screenshots
• Collapse persistence -- your expand/collapse state remembered across sessions
• Window position memory -- saves and restores across restarts and multi-monitor setups
• Code-signed Windows installer -- verified Certum certificate, no SmartScreen warnings

EVEMon was created by Jimi Charalampidis and 57+ contributors (2006-2015), then maintained by Peter Han (2015-2021). Their 20 years of work built the foundation that EveLens stands on. This project is a direct continuation of that lineage -- same GPL v2 license, same commitment to the EVE community.

I'm not accepting donations -- I just want to know if EveLens makes your EVE life a little easier. If it does, that's enough for me. Building something people genuinely find useful and actually use is what drives me. Share it with your corp, mention it in a fleet chat, or just drop me a message and tell me what you think. If it works for you, that would mean the world -- not ISK. I take donations in kind words. o7
