| Tool | Primary Language | Pricing Model | Key Strengths | Key Limitations | | :--- | :--- | :--- | :--- | :--- | | | FoxPro | Commercial ($399) | Gold standard for FoxPro. Decompiles, recovers, and protects VFP apps. Supports versions 3-9. | Specifically tied to FoxPro; not for other languages; relatively high cost. | | dnSpy | .NET | Free (Open Source) | Excellent for modern .NET apps. Allows real-time assembly editing and debugging of decompiled code. | Completely unsuitable for FoxPro executables; works only on .NET assemblies. | | Ghidra | Multi-Language (C/C++, Java, etc.) | Free (Open Source) | Powerful, full-featured reverse engineering framework from the NSA. Supports x86, ARM, and many other CPU architectures. | Overkill for a database-driven FoxPro app. Does not understand FoxPro's unique pseudo-compiled format and requires expert-level knowledge. | | IDA Pro | Multi-Language | Commercial (High Cost) | Industry-leading disassembler and debugger for deep binary analysis; supports dozens of processors and file formats. | Extremely expensive; its primary focus is low-level assembly analysis, not reconstructing FoxPro's high-level source code. |
and similar tools specifically target FoxPro 2.5 and 2.6 executables, providing a streamlined decompilation path for DOS-era legacy applications. foxpro decompiler
Visual FoxPro (VFP) remains one of the most resilient data-centric programming environments ever created by Microsoft. Despite its official retirement, thousands of mission-critical legacy applications worldwide still run on its engine. | Tool | Primary Language | Pricing Model
