The PyMemoryEditor GUI App

PyMemoryEditor ships with a polished cross-platform GUI built on PySide6 (Qt for Python). It’s a Cheat Engine-inspired memory scanner that exercises every public surface of the library — so it doubles as a living demo and a teaching tool.

If you’re new to memory editing, start with the app before writing code.

PyMemoryEditor app attached to a running process

Install

pip install "PyMemoryEditor[app]"

The app extra pulls in PySide6 and other dependencies. The core library remains dependency-free.

Launch

From any terminal:

pymemoryeditor

The app opens with the Open Process dialog, where you pick a target by name or PID.

What’s inside

🎯 Scanner

  • Every ScanTypesEnum mode

  • All integer widths, Float, Double, Boolean, String (UTF-8), and Byte Array

  • Range, AOB / byte-signature (IDA-style), and regex search

🧲 Refine workflow

  • First Scan → Next Scan (Cheat Engine style)

  • Six more comparison modes (increased, decreased, changed, …)

  • Live progress bar

📋 Cheat table

  • Live value updates

  • Freeze or overwrite values continuously

  • Per-entry custom labels

  • JSON import / export

🗺️ Memory map

  • All regions with their attributes (address, size, R/W/X permissions)

  • Auto-refresh as the memory layout changes

  • Allocate and free memory directly from the map

🔬 Hex viewer

  • Live hex dump with in-place write-back

  • Jump to any address, with auto-refresh

📦 Modules

  • All loaded modules (DLLs / .so / .dylib) with base address, size, and path

  • Auto-refresh as modules are loaded or unloaded

  • Double-click to open in the Hex Viewer

🧩 Pointer scan

  • Same engine as scan_pointer_paths

  • Save / load scans as JSON

  • Rescan and compare to narrow results down

Cross-platform dark theme

The app ships with several built-in dark themes (Kali Teal by default). Pick one from the Theme button on the toolbar; your choice is remembered between runs.

Typical workflow

  1. Open a process from the startup dialog (or later via File → Change Process…).

  2. Run a First Scan: pick the value type, type the value you can see, hit First Scan.

  3. Refine with Next Scan after the value changes — pick Exact Value with the new number, or one of the increased / decreased / changed shortcuts.

  4. Double-click a result to add it to the Cheat Table.

  5. Freeze the value with the checkbox or change it from the Cheat Table.

  6. (Optional) Run a Pointer Scan on the result to find a chain that survives restarts.

Importing & exporting

The Cheat Table and Pointer Scan results are stored as plain JSON, so you can:

  • Share a cheat table with a friend.

  • Version-control your saved pointer scans.

  • Diff scans by hand.

The pointer-scan format is documented in PointerPath.

When to use the app vs the library

Use the GUI when…

  • You’re exploring a target interactively.

  • You’re learning memory editing.

  • You want to inspect what’s available before writing code.

Use the library when…

  • You want to script a workflow or build a tool.

  • You want to embed memory access into a bigger application.

  • You need batch processing, automation, or CI integration.
