Powerful open‑source debugger for Windows reverse engineering
Alternatives
How to Decide
x64dbg is a powerful open‑source debugger for Windows reverse engineering used by reverse engineers and malware analysts. The alternatives split into a few clear camps: ghidra is chosen for its multi‑architecture support, built‑in decompiler and extensive scripting API; Glance is chosen for its lightweight self‑hosted dashboard, low resource usage and simple JSON/HTML widget extensibility.
When comparing alternatives to x64dbg, consider (1) OS compatibility – x64dbg runs Windows‑only while ghidra is cross‑platform and Glance runs on Windows, macOS and Linux; (2) breadth of analysis features – x64dbg focuses on debugging, ghidra adds disassembly, decompilation and collaborative analysis, whereas Glance provides a dashboard rather than low‑level debugging; (3) extensibility model – x64dbg relies on C++ plugins and Python scripts, ghidra offers a Java‑based API and custom plugins, and Glance extends via JSON/HTML widgets; (4) resource footprint – x64dbg is a full‑featured debugger, ghidra requires a JVM and more memory, while Glance runs as a <20 MB binary with minimal overhead.
