ED Exo Compare 1.2.5 — portable

A journal-linked exobiology companion for Elite Dangerous. It reads your local journal, merges scans and organic signals, and predicts the candidate species on a body from FSS/DSS telemetry alone — with payout ranges, first-footfall tracking, a system map, a customisable HUD and a species encyclopedia.

This release is the single-file portable build. For the unpacked program folder plus the two console builds, see v1.2.5-zip — same version, same code.

Download EDExoCompare.exe and run it. Nothing is installed.

The galaxy map is rebuilt in 3D, and it now tells you where to go next.

New: the 3D galaxy map

The galaxy icon in the top bar opens it, in its own window.

• Every system with recorded biology — all 5.3 million, drawn in 3D over the Milky Way, with the region borders and names. It starts top-down; drag with the right mouse button to tilt and turn, the left to pan, the wheel to zoom where the cursor is.
• Groups by sector and by neighbourhood (1,280, 320 and 80 ly grids that stay put as you zoom). Click a ring to fly in; a sector's ring also lists its 15 most valuable systems.
• Click any system for its region, distance from Sol, what has been recorded there and the species with their prices.
• Your own systems on top: amber still waiting for you, green done (mapped or sampled), grey visited — plus this session's jumps and your ship. Me flies to it.
• Find a system, sector or region by name. Search (Recorded / Could be there) and the Codex map (per region: logged, partly, not yet) are part of this map now.
• The map loads fresh each time it opens and lets go of its memory a few minutes after it closes.

New: where to go next

• Worth ≥ hides every system below the value you set, galaxy-wide, and says how many are left (338 k systems at 20 M or more, 23 k at 50 M, 260 at 100 M).
• Next target flies to the nearest system above that value that you have not mapped or sampled, opens it and copies its name for the game's galaxy map. Skip moves to the next one (remembered for the session); skip visited also leaves out everywhere you have been.
• Plan chains the next 3, 5, 8 or 10 targets — each the nearest to the last — with each leg's distance, the total distance and the total value, drawn as a numbered line on the map. Skip a stop and the plan is worked out again without it. Copy names puts them all on the clipboard, one per line.

Values on the map are the recorded species at 1×: those systems come from other commanders' records, so first footfall is most likely gone there.

Without WebGL 2 the old 2D map opens instead; it is still one click away as Classic map.

Linux —

Still untested on a real Linux desktop with the game running. Both files are attached to v1.2.5-zip: EDExoCompare-1.2.5-x86_64.AppImage (launcher, tray, HUD overlays; needs FUSE 2 or --appimage-extract-and-run) and EDExoCompare-1.2.5-linux-x64.tar.gz (the browser build). Details in the README, under Linux. An issue saying what worked and what did not is welcome.

No journal re-read this time.

Where your data lives

%LOCALAPPDATA%\ED Exo Compare\ — settings, your LAN key, your EDSM credentials if you add them, the species you have scanned on foot, your Fix corrections, the journal folder you chose, your HUD layout, where your windows were, the systems you looked up on Spansh (kept 30 days), the shared exomastery folder, and the prediction caches. Nothing of yours is kept in the program folder, so replacing it on an update loses nothing. On Linux the same lives in ~/.config/edexo-compare.

Your journals are read, never copied out. Uploads to EDSM, Canonn and EDDN happen only if you turn them on yourself. Looking a system up sends only its name or number to Spansh.

Windows will say the publisher is unrecognised. The executable is not code-signed, so SmartScreen asks first: "More info" → "Run anyway".
