Permissions and credits
Lightweight app that lets you back up your companions, star ships, multitools and freighters (along with custom thumbnail), share with others (discord+bot available) and import back into any save at any time! More to come...

What's New:
  • Freighter backup/restore!
  • Many UI bug fixes. 

NOTE: If you encounter any bugs, try updating in app as they have likely been fixed, but not uploaded here yet. They are available via the updater in app. 

Previous Updates:
  • Multitool support is out of beta!
  • Lots of touch ups and bug fixes (mainly UI related, file saving has had no bugs since release)
  • The NMS Seeds Central Discord as a bot now that will display the thumbnail and some stats when you share a backup file there. Easy!
  • Larger thumbnail viewer. Info viewer.
  • Added bonus example thumbnails for all the non tamable species (which can be tamed with mods)
  • Thumbnail saving! 
  • Drag+Drop or printscreen/snip pasting.
  • With a tool for cropping images.
  • Images save to the backup files.
  • Program scans backup files for images to display against your savegame (compares seeds)
  • LAST UPDATE doubled thumbnail sizes. Added a few more QoL features. Check it out!
  • Added a starship tab, that lets you backup and restore starships too!
  • Updated to work with Expeditions

Coming Soon:
  • Places backing up/restoring (like a simple bookmark + thumbnail teleport system, with sharing) is next!
  • See Release Notes in-app for more of my todo list.


Does what it says on the tin: a simple GUI app that lets you quickly backup your companions or ships to a small 2kb file (about 350kb if you save a thumbnail), that you can share (a discord is included). You can use the tool to import these into any slot on any save. You can do so even while the game is running (just save/load saves to reflect changes)

Tool Philosophy:

I can imagine it was a tough question for the devs and there were many meetings, and ultimately it was decided, despite the cons, players would be allowed 6 companions at a time, total. However, the cons are real:

  • there are quintillions of potential creatures out there, and how can a player be expected to know which ones they are never going to best, and dare to grow attached to...
  • it's so easy to tame, that one ends up filling all their companion slots very quickly...
  • if one wants to creature collect, one is completely out of options...

Generally speaking, it leads to a dilemma of always wondering if one should risk growing attached to any one Companion, and that might lead to people either getting stuck with their first few Companions forever, or never getting attached and constantly cycling through them ad infinitum

So here's a tool that removes this dilemma! You can easily back up and restore your creatures on the fly, with nothing but a couple of clicks, you don't even need to restart the game! The app has a function, helpful GUI that helps make things simple and clear. 

Since then, this tool has expanded to allow you to do the same with ships, and multitool support is inbound!


There are two options:

  1. Offline installer. Download and extract this, and run setup.exe. The program will be installed and available anytime from your start menu. Smartscreen might flag it, simply click "More info" and "Run anyway" to proceed. 
  2. Portable exe, simply extract it and run the NMSC_Portable.exe anytime you want to run the application!

NOTE: There is an optional version of the app that has a convenient in-app Updater. Click the Update icon in the app and follow the instructions to set that up, which will allow you to update the program in 3 clicks! The tool might need updating from time to time as it is prone to break like all mods, when there is a big game patch... The tool may add features and improvements as well. The offline versions here will be updated less frequently and quickly.

The tool is intuitive and full of useful instruction prompts, and you can click the ? icon to bring up more detailed instructions at any time, as well as watch the official youtube video guide. 


NOTE: Use the tool at your own risk. The tool does back up your save files when updating them (up to 3 at a time, for each save, so don't use up all three at once before you are 100% sure you are happy with the changes you have made). Report any bugs here or on the discord or to [email protected] if urgent.

I will aim to maintain the mod, improve it, support it to the best of my ability, and update it whenever a game patch breaks it! A lot of work has gone into it to make it as high quality as possible. Feel free to buy me a beer via the paypal donate button in the app, if you enjoy the tool and wish to contribute, but the tool is and always be 100% free!
