Real editor screenshots
Open the editor, choose a save and change inventory, ships, rewards and more from a familiar desktop UI.
Why use it
Fix problems, save time and edit with control.
Use it for stuck progress, inventory cleanup, ship changes, reward unlocks and the smaller fixes that are hard to do in game.
Skip repetitive grind carefully
You can add resources, resize inventories and unlock the next practical step without turning the whole save into guesswork.
Manage ships, rewards and account data
The editor covers far more than inventory. It reaches ships, freighters, companions, words, glyphs, rewards and other progression-heavy systems.
Handle advanced edge cases with control
Use raw JSON only when the normal screens do not expose what you need or when a repair job gets unusually specific.
What it can edit
Inventory, ships, rewards, discoveries, settlements and more.
The editor covers everyday changes and deeper repair work. Start with the normal screens, then move into advanced tools only when you need them.
Save Management & Backups
Open the right slot, keep a rollback path and make deliberate changes instead of editing blind.
Inventory & Items
Move, clone, add, repair, recharge and reorganize inventory data without digging through raw save structures first.
Ships, Freighters & Multitools
Handle ship class, seed and layout work alongside freighter, frigate and multitool data in a purpose-built UI.
Discoveries, Words & Unlocks
Edit knowledge, products, glyphs and other progression-linked discovery data without hunting for hidden switches.
Account Data & Rewards
Unlock expedition rewards, Twitch rewards and account-level entitlements through the editor's account-oriented workflows.
Companions & Settlements
Adjust pet and settlement-related values when the built-in game route is too slow, too rigid or already broken.
Raw JSON for Advanced Users
When a normal screen does not expose what you need, the raw JSON editor gives you direct access to the underlying save structure.
Safe and practical
Make one change at a time and keep a backup.
A careful workflow beats a big risky edit. Back up the save, test one change, then continue if everything looks right in game.
If you want to check file names, dates or recent issue reports before downloading, open the GitHub project first.
A clean rollback copy matters more than any promise. Keep one before rewards, coordinates, JSON edits or large inventory changes.
Depending on the update, the extracted folder can include an EXE or an MSI installer. Extract the archive first, then run the included file.
After a large update, new rewards, items or save fields can lag behind the rest of the editor for a while.
