Don't let cheaters tank your game's reviews, economy, or player trust. Anti-Cheat Toolkit (ACTk) helps you keep things fair without building a security stack from scratch. It wraps practical, field-tested techniques into a Unity-first toolkit you can drop in fast and extend when needed.
🔒 Why ACTk
- Save time and reduce risk. Ship proven protections instead of homegrown experiments.
- Easy to add, easy to scale. Start with a few calls, grow into deeper checks later.
- Built for Unity workflows. Client and server use, multiplayer friendly, Hybrid DOTS ready, Unity 6 compatible.
- Transparent by design. Full source code included so you can inspect, debug, and customize.
- Maintained and trusted since 2013 with regular updates and responsive support.
💡 Key Benefits
- Protect revenue and player trust: stop common cheats that inflate currency, bypass timers, or break PvP.
- Cut implementation effort: swap PlayerPrefs to ObscuredPrefs, enable detectors, wire your own responses.
- Broad coverage in one package: memory value protection, save encryption and genuine checks, speed/time/wallhack detection, foreign assembly detection, build tamper checks, Android install source validation, screen capture prevention.
- Lightweight and practical: background hashing, detectors that stay out of the way during normal play.
- Multiplayer ready: works with Photon, Mirror, Netcode, Fish-Networking, and similar stacks.
