NomNom is the most complete savegame editor for NMS but also shows you additional information around the data you're about to change. You can also easily look up each item individually to examine its attributes, independently of a savegame, or get other useful information that are not related to a specific one (but enhanced if one is loaded).

NomNom is now in beta state. This means for you that some things may still not be 100% finished but the general state of the tool is a lot better than before. If you encounter bugs or when you think something doesn't work as expected or could be improved, let me know!
All available features are tested while implemented but mistakes can happen, so be aware of that and backup your saves!
The features can be divided into the different main parts:
Manager Manage your saves!
Automatic backup.
Save your save as human-readable JSON.
Copy, move, and swap slots to another.
Delete your save.
Editor Edit your save for your needs!
Ability to manage fleets, change data values like currencies and stats, and organize inventories.
Ability to fast travel to any system you like, trigger space battles, and clear portal interference.
Ability to edit your knowledge and recorded experiences.
Have a look at the screenshots as well, to see what NomNom is capable of.
Each version of NomNom is built with the latest game version (at that time) in mind and the version number is reflecting that. Each one is also backwards compatible down to Beyond 2.11 and even saves before that can still be edited via the build-in JSON editor. If you use it with a newer game version branch than the one it was built for (e.g. 6.00), things should work as usual in most cases but there can always be a breaking change.
NomNom is compatible with every platform No Man's Sky is available on (some work better than others though). You can select a specific account/folder with you saves or, for platforms on PC, one level above if you have multiple accounts. A complete and always up-to-date overview with additional notes can be found on GitHub.
Instructions
After downloading and extracting the zip file you'll find a few files. All you need to care about is the executable (NomNom.exe) but new folders may be created at runtime (e.g. for backups) that will become relevant to you.
You may want to create a shortcut to the executable for easier access.
As the tool includes an automatic backup functionality you don't need to do it manually but if you want to be absolutely safe, do it.
At first start the tool locates your saves at the default location of each platform but if that fails, you must select it manually.
Select a slot.
Start tinkering!
If you like NomNom and want to support me in its further development, you can do so via the donation options above or on Buy Me a Coffee, GitHub, Ko-fi, and Patreon. I will appreciate it! There won't be a paywall though.
The is also a dedicated Discord server where you'll find all information in one place, firsthand. Please read the rules first, to gain full access. If you need (or want to offer) help, found a bug, have a suggestion, or something else regarding NomNom, you will find, or can post it there.
Issues created here on Nexus Mods or via another channel will of course also be addressed.
