What is x64dbg.com?

Updated

x64dbg.com is the official website of x64dbg, an open-source x64/x32 debugger for Windows. The site is where you download the debugger, get its source code, and find documentation, plugins, and community links. It is aimed at people who need to inspect and debug Windows DLL and EXE files — typically reverse engineers, malware analysts, and developers troubleshooting compiled binaries.

What the site offers

The homepage is primarily a project landing page. The main entry points are:

  • Download — get the debugger build.
  • Source — access the source code (the project is GPLv3, and both executable and source are provided).
  • Blog — project news and updates.
  • Docs / Wiki — documentation and a fuller contributor list.
  • Plugins / Issues — plugin ecosystem and the issue tracker.
  • Discord — community chat.
  • Donate — optional support for the project.

What the software does

x64dbg debugs both x64 and x32 applications through a single interface. Per the site, it supports full-featured debugging of DLL and EXE files (via TitanEngine), with a familiar but customizable interface.

Key capabilities listed on the site:

Area What it provides
Disassembly Fast disassembler (Zydis), IDA-like instruction token highlighting, jump arrows in a sidebar
Views Memory map, symbol view, thread view, source code view, graph view, dynamic stack view, content-sensitive register view
Symbols Basic PDB debug symbol support
Analysis aids C-like expression parser, import reconstructor (Scylla), executable patching
Automation Integrated, debuggable ASM-like scripting language; plugin support with a growing API
Customization Fully customizable themes and color scheme; user database (JSON) for comments, labels, bookmarks

It is built on open-source libraries including Qt, TitanEngine, Zydis, Yara, Scylla, Jansson, lz4, XEDParse, asmjit, and snowman, and is under active development.

Who it is for

Choose x64dbg if you need a free, open-source Windows debugger for binary-level work — stepping through DLL/EXE code, inspecting registers and memory, patching executables, or scripting repetitive analysis. If you only need source-level debugging of your own code, a standard IDE debugger is usually the simpler fit; x64dbg's strength is working with compiled binaries where source is unavailable.

To get started, use the Download link on the site, then consult the Docs and Wiki for usage details and the plugin API.
