Frequently Asked Questions

Yes. Every feature is free and there is no paid version. The key system is what keeps it that way: instead of charging money, the developers ask you to complete a short verification to get your key. It takes a few minutes, and then the whole app is unlocked.

The official build from this site is clean. The danger is not Hydrogen itself, it is the fake copies floating around on random websites and social media, which are often bundled with malware. Always download from hydrogenexecutor.org and nowhere else. Also be honest with yourself about one thing: running any executor breaks Roblox rules, so use it on an account you can afford to lose.

Android, iOS, Windows, and Mac are all supported, and the experience is basically identical across them. The same key works everywhere, so you can start on your phone and pick up on your PC without doing the key process twice. If your device runs Roblox without trouble, it will handle Hydrogen fine.

Yes, the app asks for a key the first time you open it. Tap the Get Key button inside the app, work through the short verification checkpoints in your browser, and your key appears at the end. Copy it back into the app and you are in. Keys expire after a while, but getting a fresh one works exactly the same way. The full walkthrough is on the Get Key page.

Download the latest build from the Download page on this site and install it right over your current copy. Your settings carry over and your key usually keeps working, so there is nothing else to redo. I recommend checking this site after every major Roblox update, since that is when new Hydrogen versions drop.

Start with the script library built into the app, then check the Scripts page here for popular picks sorted by game. Beyond that, community script hubs and forums have thousands of options. A word of advice from experience: scripts break whenever their game updates, so if one stops working, look for a recently updated version rather than assuming the executor is at fault.

This is normal and happens with almost every script executor. Antivirus tools get nervous about any program that injects code into another running app, which is exactly what an executor does. As long as you downloaded from the official site, it is a false positive. Add an exception for the file and carry on.

Do not panic, this happens to every executor after Roblox patches. The developers usually push a compatible Hydrogen update within a short time. Keep an eye on this site, download the new version when it lands, and install it over your old copy. In the meantime, avoid spamming the execute button on the broken version.

Yes, that risk is real. Roblox does not allow script executors, and accounts caught using them can be warned, suspended, or banned. Plenty of people use executors daily without issues, but nobody can promise you will be fine. The smart move is to script on an alternate account and keep your main one clean.
