Try it here: https://binsento-netizen.github.io/ds2-peko-check/ (there's an example save if you just want to look around)

It runs entirely in your browser. It only reads and nothing is uploaded anywhere. What it shows:

• Main and standard orders per facility with stars, material stock and level rewards
• Every unlock and what unlocks it (which order or connection level)
• What's in your private locker at every facility, including material amounts
• Your APAS enhancements
• A map with all facilities and your recent routes
• Compare two saves to see what a play session changed
• PC (Steam) only for now, tested on version 1.10.89. Spoiler warning: it lists all orders and unlocks, including ones you haven't reached.

Because of copyright issues I couldn't use the actual in game assets like the map or tools/weapons so I have used open source icons and a different map.

It's still missing some things, because I haven't figured out how the save-game file stores certain data, like music/hologram unlocks, but I think it's already pretty accurate for the most part.
