03
Open Roblox & tap Start
Launch the Roblox app, join any game, then tap the floating Hydrogen bubble. Tap Inject — the panel expands and attaches in 3–5 seconds.
04

Go to Settings → General → VPN & Device Management, tap your Apple ID, and select Trust. Now Hydrogen will launch normally.

What you can run
Hydrogen supports the complete Luau scripting environment used by Roblox.
Lua / Luau
Full Luau syntax, all standard libraries and Roblox-specific globals.

Direct access to RemoteEvents, Services, DataStore and all Roblox instances.
Full accessGUI Scripts
Create custom ScreenGui overlays and user interfaces inside any Roblox game.
SupportedCloud Scripts
Sync and load scripts directly from the built-in Cloud library across devices.
Built-inAnti-Cheat Bypass Coverage
Hydrogen's injection engine bypasses all major Roblox anti-cheat systems. Updated within 24–72 hours of any patch.
Hyperion (Byfron)
Roblox's primary anti-cheat. Full bypass — memory integrity, syscall hooks, and VM detection all defeated.
Bypassed · Live
AC2 (Legacy Anti-Cheat)
Older Roblox anti-cheat layer still active in some experiences. Fully circumvented since v2.5.
Bypassed · Live
Heartbeat / WalkSpeed Checks
Server-side movement validation. Hydrogen patches local physics without triggering server flags.
Bypassed · Live
RemoteEvent Spam Detection
Rate-limiting on RemoteEvent calls. Hydrogen throttles locally to stay under detection thresholds.
Bypassed · Live
Memory Integrity Checks
CRC / hash validation of Roblox memory pages. Spoofed checksums returned in real-time.
Bypassed · Live
Process Scanner (Task Manager)
Roblox scans running processes for known executors. Hydrogen runs under a randomized process name.
Bypassed · Live
Anti-Tamper (Experimental)
New server-side tamper detection rolling out to select games. Partial bypass — 85% success rate.
Partial · v2.9.9
Kernel-Level Anti-Cheat
If Roblox moves to a kernel-mode driver (like EAC/BattlEye), Hydrogen is ready — research build in progress.
In ResearchNote: Anti-cheat bypass status is updated within 24–72 hours of every Roblox update. Always use the latest Hydrogen version for maximum compatibility. Some games may use custom server-side detection not listed here.
Common questions
Yes — 100% free, forever. There is no premium tier, no subscription, and no paywalls. We fund development through community support, not advertising.
Hydrogen Executor is clean and every release is verified on VirusTotal. Because the software interacts with Roblox's process, some heuristic scanners may raise a false positive — this is common with all executors. You can safely add an exception.
Yes! Hydrogen Executor supports Windows 10/11, macOS (Intel & Apple Silicon), Android 8.0+, and iOS 14+. See the platform guide for setup instructions for each device.
We release compatibility updates within 24–72 hours of every Roblox patch. The in-app auto-updater will notify you when a new version is ready. See the Changelog for the full history.
You can write your own Luau scripts, use the built-in Cloud Scripts library, or browse community hubs. Hydrogen runs any valid script compatible with the current Roblox version.
Hydrogen supports Windows 10/11 (4 GB RAM, 120 MB), macOS 11+ (Intel & Apple Silicon), Android 8.0+ (3 GB RAM), and iOS 14+. See the full requirements table for your platform.
