Save Flow - PlayerPrefs Editor

Save Flow turns PlayerPrefs from a black box into something you can actually see.

Unity gives you no way to list your own keys, no way to know their types, and no

history when a save goes wrong. Save Flow reads the real store — the Windows

registry, the macOS plist, the Linux prefs file and shows you everything in one

clean window, live, while your game runs.

SEE EVERYTHING

Every key, its real type and its current value in a searchable table. Search keys

AND values, filter by type, sort, and pin the keys you keep coming back to.

Values flash as your game writes them. The table is virtualised, so it stays fast

with thousands of keys.

EDIT WITHOUT BREAKING YOUR SAVE

Edits are staged, not written on every keystroke. Type freely, then Apply or

Revert as a batch and undo it afterwards if you change your mind. Ints, floats

and strings get proper fields, 0/1 ints can be shown as real toggles, and long

JSON values open in a full multi-line editor instead of a cramped text box.

SAVE STATES

Capture the entire store as a named restore point: "level 10, full inventory",

"fresh install", "QA profile". Compare any save state against your live data and

see exactly what is changed, missing or extra then restore it as a merge or a

full replace. Save states are plain JSON kept outside your Assets folder, so you

can commit them, share them with QA, or diff them in git.

A LIVE CHANGE LOG

Every add, change and delete as it happens, with timestamps, old and new values,

and a numeric delta. Filter it, follow the tail, export it to CSV, or right-click

any entry to restore the value it used to have. Numeric keys get a graph of how

they changed over time — perfect for catching the one line of code that quietly

resets your player's coins.

SAFE BY DEFAULT

Unity's own bookkeeping keys are shown for reference but are strictly read-only,

and even "Delete all" leaves them untouched. A backup save state is captured

automatically before anything destructive, destructive actions sit behind typed

confirmations, and there is a 25-step undo stack behind the whole tool.

MOVE YOUR DATA AROUND

Export to JSON or CSV, import with merge, replace or fill-missing modes, or copy

a readable key = value list straight to your clipboard for a bug report. Imports

also accept plain {"Key": value} JSON, so data from other tools drops right in.

BUILT TO LOOK RIGHT

Dark, light, or follow-your-editor-skin. Drop in your own .ttf and the whole UI

uses it. Everything is drawn procedurally, so there are no textures to import and

it looks identical in every project.

GET STARTED IN A MINUTE

A guided demo scene ships with the asset. Press Play and follow the on-screen

checklist: press buttons in the game, watch keys appear in SaveFlow, then edit

them from SaveFlow and watch the game update live. It ticks itself off as you go.

GOOD TO KNOW

SaveFlow edits the editor's PlayerPrefs store, which is the same one play mode

uses. A shipped build writes to a different location by Unity's design — an

optional in-game overlay is included for inspecting prefs in development builds

on device.

Full C# source. No third-party dependencies. Nothing is added to your project

settings, and nothing runs unless the window is open.
