Evidence basis: Reviewed Eazfuscator.NET 2026.2 documentation and current public download/purchase pages. Competitor capabilities are vendor-documented; we did not run Eazfuscator on the downloadable samples.
Official sources and license details · Our measured output and compatibility evidence
What Eazfuscator.NET is
Eazfuscator.NET is a local obfuscator and optimizer. Its documented feature set includes renaming, string encryption, control flow, resource protection and assembly merging.
Code/data virtualization is documented separately. FreeObfuscator Pro also has a method VM, but we have not established equivalent coverage or reverse-engineering resistance.
Eazfuscator.NET pricing
Eazfuscator.NET: Official purchase page checked October 23, 2026: Single Developer $399; Site License $1,699. Licenses are perpetual with one year of support/upgrades; later support renewal is separate. Deterministic obfuscation is Site-only. Verify the displayed currency, taxes and final terms with Gapotchenko.
Check the official purchase/store and evaluation sources below. An evaluation window, a perpetual license and its update/support period are different terms.
FreeObfuscator: free to use with no account. An optional Pro plan adds larger files, batch obfuscation, string encryption, control-flow obfuscation and an HTTP API for CI/CD.
Capabilities side by side
Competitor “Yes” means documented availability, not an independently tested result or inclusion in every license. Our “Paid tier” means Pro. “Not verified” is not “No”; CLI and build integrations are distinct from a hosted upload API.
| Capability | Eazfuscator.NET | FreeObfuscator |
|---|---|---|
| Symbol renaming Vendor documentation Both have compatibility exclusions. | Yes | Yes |
| String encryption Vendor documentation Ours: Pro; compare emitted output and runtime behavior. | Yes | Paid tier |
| Control-flow obfuscation Vendor documentation Ours: Pro, with compatibility exclusions. | Yes | Paid tier |
| Code virtualization Vendor documentation Ours: Pro, marked supported methods; no equivalence benchmark. | Yes | Paid tier |
| Data virtualization / homomorphic techniques Vendor documentation Separate vendor-documented features, not our method VM. | Yes | No |
| Resource encryption / assembly merging Vendor documentation | Yes | No |
| NuGet / Release-build integration Vendor documentation Ours: hosted Pro API, not a native MSBuild/NuGet integration. | Yes | No |
| Local processing Vendor documentation Vendor provides Windows setup and Linux/macOS NuGet workflows. Ours is server-side. | Yes | No |
| Hosted HTTP upload API Competitor hosted API not verified from reviewed sources; not a claim that it is unavailable. | Not verified | Paid tier |
Where Eazfuscator.NET is strong
- NuGet integration can process Release builds automatically.
- Official local workflows cover Windows, Linux and macOS; check platform requirements.
- Vendor-documented resource protection, merging and build-oriented tooling beyond our hosted workflow.
Where it costs you
- Commercial license; the download page offers a 30-day evaluation, not our permanent Free service tier.
- Deterministic obfuscation is an edition choice: the purchase page reserves it for Site License.
- Install/configure and evaluate the build integration on your own application; we have not benchmarked it.
Choosing between them
Choose Eazfuscator.NET if
- You need local processing or automatic build integration.
- You need the vendor's resource, merging or data-virtualization features and have evaluated their fit.
- You need deterministic output and have checked the Site License terms.
Choose FreeObfuscator if
- You can upload an assembly and want a free renaming trial without a local installation.
- You prefer a hosted Pro API workflow and do not need the additional local build features.
The verdict
The practical distinction is local build integration and feature coverage versus a hosted upload/API workflow. Compare the same original assembly and required settings, then check compatibility and performance. Matching feature names do not prove matching protection strength.
What to verify in your evaluation
- If build integration matters, evaluate the NuGet/Release-build workflow on your actual OS rather than treating a hosted HTTP API as the same integration.
- When evaluating virtualization, record the selected methods, settings, output size and runtime behavior. The presence of virtualization in both products does not establish equivalent coverage or resistance.
- If repeatable output matters, check edition terms: the purchase page places deterministic obfuscation in the Site License. Keep test correctness separate from byte-for-byte reproducibility.
What we actually verified
These are FreeObfuscator-only results on self-authored .NET 8 examples. We have not produced Eazfuscator.NET or .NET Reactor outputs for these inputs. This evidence does not rank the products' protection strength or performance.
| Observed case | Result | Inspect or reproduce |
|---|---|---|
| Production Free library | 3 exported types and 24 reflection-contract entries match; the unchanged consumer passes ten checks. Accessors count separately; entries are not independent runtime tests. | DLL case · Source and binaries · Contract report |
| Production Free application | Managed application type/helper renamed; four launches via dotnet and the unchanged Windows apphost have identical output, with ten checks per launch. | Application case · Source and binaries · Launch report |
| Local Pro-transform example | 2,003 compared runtime results match the original; a selected UTF-16 plaintext literal is absent after string encryption. Local engine run, not a production paid-account or virtualization test. | Method and limits · Report |
Run a comparable trial
- Start from the same original release assembly, dependencies and consumer. Record each product version, license/evaluation mode and settings.
- Separate a basic renaming comparison from additional-layer tests. Select equivalent requirements rather than assuming similarly named switches transform the same methods.
- Inspect representative methods and strings with a decompiler; record preserved or skipped code. A changed hash or file size is not a strength score.
- Run the unchanged consumer or complete application, normal and exceptional paths, reflection and serialization tests. Also measure startup, hot-path latency and output size under a defined workload.
- Report failures and exclusions alongside successes. Our captured library is unsigned, and the application case covers Windows framework-dependent .NET 8; other deployments need their own validation.

Worth knowing before you decide: what obfuscation actually protects against sets realistic expectations about how far any of these tools go.
