Hi all,
Canopus is a free, open-source (MIT) desktop companion for EVE Online, for Windows and macOS. It started as a personal tool and grew into one app that replaces the half-dozen browser tabs I used to keep open: fitting, intel, route safety, market, industry and the whole character sheet.
Fitting tool with its own dogma engine
- Built on CCP’s SDE: skills, hull and role bonuses, subsystems, module states (offline / online / active / overheated), charges, drones, implants, stacking penalties
- Live preview: hover a module and every stat updates with the difference highlighted, so you can compare without fitting
- DPS and volley with damage profile, EHP and resists per layer, cap stability, navigation, targeting
- All skills V or your character’s skills, with what to train and how long it takes
- Fit cost at Jita prices, side-by-side comparison, popular fits from zKillboard for the same hull
- EFT import / export, and save a fit straight to your in-game fittings
- Checked against the in-game fitting window: same DPS, volley and EHP on real fits
Show Info for everything: attributes with the game’s icons, a readable Effects tab (“when active: shield resistances +32.5%”), the skill tree with your levels, variations, reprocessing, hub prices.
Combat simulator
Your fit against any opponent on an interactive map: drag ships and velocity vectors (or pick orbit / head-on / kiting), switch ammo on both sides and see applied DPS per weapon with the reason it drops (tracking, falloff, explosion radius / velocity), damage per tank layer against reps, and who dies first.
Intel
- Local scan: Ctrl+A, Ctrl+C in Local (Cmd on Mac) and every pilot is checked for corp / alliance, age, kills and losses, danger ratio and usual ships. New arrivals are highlighted, and you get an alert when someone dangerous jumps in
- Intel channels: follows your alliance intel chat logs, recognises systems (including shorthand like “1DQ”) and ships, and shows how many jumps away each report is. “clr” / “nv” count as all clear
- D-scan and fleet window analysis: interdictors, bombers, recons, logi, capitals
- An always-on-top overlay for windowed / borderless mode
Travel
- Route safety: every system with ship / pod kills in the last hour and gate camps; set the destination in game with one click
- Jump planner for capitals and black ops: range, fuel and jump fatigue along a cyno chain
- Wormholes: class, lifetime, mass limits and which of your ships can pass, plus Thera / Turnur connections from EVE-Scout
Market, industry and more
- Prices in all five trade hubs, order book, 90-day history, arbitrage between hubs with taxes and profit per m³
- Loot appraisal, LP store, your orders with outbid detection
- Manufacturing and reaction calculator, industry jobs, PI extractor timers
- Signatures: copy the probe scanner and Canopus remembers sites per system and marks new and vanished ones
- Character sheet, skill planner, assets with Jita value, wallet, contracts, mail, calendar, fleet management
- Notifications for every character: skill queue, PI, industry jobs, jump fatigue, outbid orders
Fair play
Canopus only uses official and player-visible data: ESI, the SDE, the chat and game logs the client writes to your Documents folder, and what you copy to the clipboard yourself. It never reads client memory or the screen and never automates input, the same approach as Pyfa or RIFT. Login is standard EVE SSO with PKCE; tokens stay encrypted on your computer. In-game actions (set destination, save fits, fleet invites…) go through official ESI and are off until you enable them.
Download
- Windows 10/11: installer or portable exe
