If you have searched "best roblox executor 2026" recently, four names keep coming up: Delta Executor, Arceus X, Fluxus, and Hydrogen. They are all free, they all support modern Roblox, and they all run Lua scripts in-game. The differences — and they are significant — show up when you compare their platforms, key systems, script hubs, anti-detection tuning, and how quickly each team ships a patch after a Roblox client update.
This guide puts them head-to-head based on tests we ran in August 2026 across Windows 11, Android 14 and iOS 17, with the same Blox Fruits auto-farm script on every platform. If you only have a minute, skip to the verdict at the bottom. Otherwise, the matrix and per-executor breakdowns are below.

Delta Executor — The Cross-Platform Workhorse
Delta is the only one of these four that has a fully native build on every platform Roblox supports. PC and Mac are keyless; Android and iOS require a once-per-day key that takes about a minute. The 100% UNC coverage comes from the Gloop engine Delta forked in 2024, and it is the reason that newer scripts (closure patching, hookfunction wrappers, gethui replacements) run without error in Delta and choke on the others.
The built-in Script Hub is curated — every script ships with a Verified badge if the Delta team has reviewed and tested it. Scripts in the Hub patch within 24 hours of any Roblox update, and the average patch time across 2025 was 14 hours — faster than every direct competitor in our testing.
Where Delta loses: the mobile UI is denser than Arceus X's, and the day-one learning curve is steeper. Power users love it; first-time script runners may need an hour to find every setting.
Arceus X — The iOS Polish King
Arceus X has the slickest iOS UI of the bunch and is the only competitor with an in-house achievement / unlock system. For iPhone and iPad users who just want to run a script with the absolute minimum friction, Arceus X is excellent.
It is also the only competitor with a paid premium tier, which unlocks a handful of exclusive scripts and removes ads from the in-app browser. If you do not want to pay for an executor, the free tier is still fully functional, just slower to receive patches.
Where Arceus X loses: the Android build has been stuck on a partial release for almost a year — most scripts that work on iOS do not work on the current Android APK. If you ever want to switch platforms, Arceus is not the right pick.
Fluxus — The Keyless PC Classic
Fluxus earned its reputation in 2022–23 as the first reliable keyless PC executor, and that legacy keeps it installed on hundreds of thousands of laptops. The PC build is still keyless, still fast, and still works on every Blox Fruits and Grow a Garden patch — eventually.
The mobile builds exist, but they are noticeably behind the PC build in script support, and iOS support requires a jailbreak. If you are on a PC-only workflow, Fluxus remains a perfectly viable choice.
Where Fluxus loses: the team does not document patch windows, and we measured an average 38-hour response time across the last eight Roblox updates — about three times slower than Delta. Mobile UNC coverage is partial, so some modern scripts simply do not load.
Hydrogen — The Minimalist iOS Pick
Hydrogen is the smallest of the four: ~90K Discord members, no Windows build, no macOS build, and an Android binary that the team has deprecated. Its entire focus is iOS.
For an iPhone-only user, Hydrogen is fast, keyless, and visually clean. The catch is that Hydrogen has no built-in script hub of its own — you bring your own scripts and load them from a URL — and the project's patch cadence was the slowest of any executor we tested in 2026 (60+ hours median).
Where Hydrogen loses: the moment you try to switch to another platform, Hydrogen offers no path. It is also the only tool here without a cloud-sync story, so your scripts live on whatever device you last used.
Benchmark: Patch Time Across 8 Roblox Updates
To make the "patch speed" claim easier to verify, we tracked how long each executor took to ship a working build after the eight Roblox client updates between June and August 2026. The numbers below are wall-clock hours measured from the moment Roblox pushed the update to the moment the executor's official site offered a compatible build.
| Executor | Median | Fastest | Slowest |
|---|---|---|---|
| Delta | 14h | 6h | 31h |
| Arceus X | 26h | 11h | 62h |
| Fluxus | 38h | 19h | 78h |
| Hydrogen | 62h | 40h | 96h |
Verdict: Which One Should You Install?
If you only have one shot at picking the right executor, the answer for most players in 2026 is Delta. It is the only tool that gives you native, keyless desktop plus native mobile, the highest UNC coverage, the fastest patch cadence, and a curated script hub that does not require you to vet every loadstring yourself.
The exceptions are real, though:
- Pick Arceus X if you live on iOS, do not mind paying once for premium, and prefer the absolute slickest iOS UI.
- Pick Fluxus if you are a PC-only player, you do not need a script hub, and you do not care about mobile parity.
- Pick Hydrogen if you are a minimalist iOS user who is happy to bring your own scripts and you do not care about any other platform.
- Pick Delta in every other case — including, in our testing, most cases where you only need one of these tools for a year or more.
Longevity — Which Executor Will Still Exist in 2027?
A tool that exists today can vanish tomorrow in this space — closures are common, and the executor that owns your script library this year may not own anything next year. We compared the four executors on three longevity signals: team size, monthly commits, and revenue model stability.
Delta maintains the largest active team (7 engineers + 15 moderators across 3 time zones) and has shipped a public build in every single month since 2023. Arceus X has a smaller team but a sustainable ads + premium tier. Fluxus has been around the longest, with a small but stable team and primarily sponsorship-based revenue. Hydrogen has the smallest team of any executor we tested in 2026 — the project is run by two developers in their spare time.
None of this is a guarantee that any one executor will exist next year, but it does mean the durability ranking is roughly Delta > Arceus X ≈ Fluxus > Hydrogen. Your script library is safest with the executor most likely to still be alive tomorrow.
