The most popular Roblox script executor for mobile – free, fast and regularly updated.
Last updated: September 30, 2026
About Hydrogen Executor
Hydrogen Executor is one of the most widely used Roblox script executors for mobile devices. It lets players run Lua scripts inside Roblox games, unlocking custom features, automation and gameplay tweaks that are not possible in the standard app. If you prefer a PC and mobile option with no key system, Xeno Executor is a popular alternative.
Version 2.740 brings improved stability, faster script execution and support for the latest Roblox updates. The built-in script hub gives you one-tap access to popular scripts — browse our free scripts collection for ready-to-run options — and the clean interface makes it easy for beginners to get started within minutes.
Whether you want to automate grinding, test your own scripts or just explore what custom scripting can do, Hydrogen Executor remains the go-to choice for mobile Roblox players in 2026.
Safety note: Hydrogen Executor is a third-party tool not affiliated with Roblox Corporation. Using any executor can carry account risks, so consider using an alternate Roblox account and download only from trusted sources like this page.
