Short answer
GuardingPearSoftware Obfuscator Pro costs $79.99 (one-time purchase). It includes symbol renaming, string obfuscation, fake code injection, method control flow, and anti-tamper checks. It runs directly inside your Unity build pipeline and patches your game assets when it renamesMonoBehaviour classes and other serialized types. A Free tier exists if you want to test the pipeline first.
Beebyte Obfuscator costed about $80, and was the best known Unity obfuscator from about 2015 to 2024. It did renaming, string hiding, and fake methods, and it understood many Unity "do not touch this" cases. It did not offer real control flow. Public listings now mark it deprecated. Compatibility notes limit it to selected 2021.3 and 2022.3 builds, and newer Unity versions should be treated as incompatible.
In simple words:
- Choose GuardingPearSoftware Obfuscator if you ship on current Unity and want an asset that is still maintained.
- Choose Beebyte only if you already own it and you are stuck on an old LTS that it still accepted.

What GuardingPearSoftware Obfuscator does
GuardingPearSoftware Obfuscator is a Unity cybersecurity asset. After you enable it, protection runs when you press Build. You do not export a DLL, open a second Windows GUI, then copy files back. The same hooks fire for a customBuildPipeline.BuildPlayer script and for cloud builders that run a normal Unity player build.
The package can rename namespaces, classes, methods, fields, properties, and events. And also rename the Unity types that most tools skip: MonoBehaviour, ScriptableObject, and Playable classes. After the rename pass, it updates scenes, prefabs, and other assets that still store those names.
Unity stores a lot of meaning as text. A button in the Inspector may keep the method name it should call. An animation event may keep a string. A serialized field on a component keeps its field name. Addressable bundles can keep script references too. Obfuscator has compatibility settings for those cases: Inspector values, UnityEvents, animation events, reflection and coroutines, UI Toolkit, and Addressables (JSON and binary catalogs, custom local or remote paths, and Addressable Shield on Unity 6 and newer).
It also hides strings, adds random fake code, and can suppress simple ILDasm inspection. Mono builds can get control flow and assembly signing. Standalone builds can get integrity checks. Mapping files stay available so crash logs are still readable after release. MonoBehaviour and namespace renaming are Obfuscator Pro features.
The tool stays local. You do not send the game to a cloud protector. Because it runs inside Unity and Tuanjie, it works on any platform where those editors run, including Windows, macOS, and Linux build machines.
What Beebyte does
Beebyte obfuscates compiled assemblies, not your source files. That part is the same idea as most Unity obfuscators. You set options in the Inspector, then the package rewrites names when you build. Its known feature set:- Rename classes, methods, parameters, fields, properties, and events
- Hide string literals
- Add fake methods
- Respect many Unity types that must keep their names
- Work with assembly definition files
- Support IL2CPP on the Unity versions it still listed
MonoBehaviour renaming on newer Unity. From 2018.2 onward, that feature was limited, especially outside some standalone cases. Public copies of the listing say only LTS Release 2022.3.29 and LTS Release 2021.3.38 were valid. Other versions, including newer LTS releases, should be considered incompatible.
Search is not the same as "best tool to buy today." The name still shows up first in a lot of old threads. The listing is deprecated, and the publisher is no longer an active Unity-store default.
The biggest difference
Beebyte won on history. GuardingPearSoftware Obfuscator wins on current Unity use. If you start a Unity 6 or a current 2022 LTS project today, Beebyte's own compatibility notes are the problem. You also get only rename-and-junk protection. That was enough when few Unity teams used any obfuscator. It is a weak plan if you want more than shorter names. GuardingPearSoftware Obfuscator still ships 2026 updates. It can rename Unity types and patch the assets that point at them. Mono builds can get control flow and anti-tamper. Addressables work is part of the product, not a forum workaround. Price is close. Both sit around $80. The gap is maintenance and how far the rename pass can go without breaking scenes.Why Unity-aware renaming matters
Unity does not only compile C#. It also saves type names and member names inside assets. That is how the Inspector, scenes, and prefabs keep working after you close the Editor.If a protector renamespublic class PlayerHealth : MonoBehaviour { [SerializeField] private int maxHealth = 100; public void TakeDamage(int amount) { maxHealth -= amount; } }
PlayerHealth or maxHealth and never updates the prefab, the GameObject can lose the script or reset the value. If it leaves those names alone so the prefab stays valid, attackers still search for PlayerHealth and find the logic.
GuardingPearSoftware Obfuscator is built for that tradeoff. It can rename the class and the serialized field, then update the related assets so the GameObject still points at the new names. Beebyte understood many Unity skip cases, but MonoBehaviour renaming was limited after 2018.2. On a current project, that often means the names attackers look for first stay readable.
Which one should you pick?
Pick GuardingPearSoftware Obfuscator if you want:- A Unity obfuscator that is still updated
MonoBehaviourandScriptableObjectrenaming with asset updates- More than rename-and-junk protection
- A Free tier to test the workflow
- One seat price close to what Beebyte used to cost
- You already paid for it
- Your project is on a Unity version it still accepted
- You only need light renaming and you can live without new updates
