Telerik Justdecompile Offline Installer Updated _hot_ May 2026

The Short Answer (Updated)

There is no longer an officially published, standalone offline installer for the free version of Telerik JustDecompile.

Since around 2021–2022, Progress (Telerik) has shifted to distributing JustDecompile exclusively through:

JustDecompile vs. Other Decompilers (Offline Edition)

How does the updated offline installer compare to competitors?

| Feature | JustDecompile (Offline) | dnSpy (Older) | ILSpy | dotPeek | |--------|------------------------|--------------|-------|---------| | Offline installer available | ✅ Yes (official) | ⚠️ Third-party only | ✅ Yes | ✅ Yes | | Supports .NET 9 | ✅ Yes | ❌ No | ⚠️ Partial | ❌ No | | Command-line interface | ✅ Full | ❌ No | ✅ Basic | ❌ No | | Plugin ecosystem | ✅ Yes | ❌ No | ✅ Yes | ❌ No | | Active support | ✅ Yes (Progress) | ❌ Abandoned | ✅ Community | ❌ (JetBrains focus on Rider) |

For over a decade, JustDecompile served as a "fast and free forever" .NET decompiler, helping developers recover lost source code and analyze assemblies.

Performance: It gained popularity for being significantly faster than leading competitors, particularly when decompiling .NET Framework assemblies.

Offline Flexibility: Telerik provided an offline installer (as an MSI or ZIP file) specifically for developers who needed to work in environments without internet access or who wanted to run the tool from a portable drive.

Open Source Engine: While the UI remained proprietary, the core decompilation engine was made open-source to allow community contributions. Current Availability and "Updated" Versions

The "New" Version: The original team behind JustDecompile has continued development under a new name: CodemerxDecompile. This version uses the same engine and remains free, serving as the spiritual "updated" successor to the Telerik-branded tool. Recommended Alternatives
