Best Roblox Executor and How Delta Compares

Roblox Executor Comparison Table

Seven names come up in every "which executor" thread, and they split cleanly into phone apps and Windows programs. Each row reflects the executor's own site and a public status tracker in mid October 2026.

If Delta is the one you want on a phone, the latest Delta APK for Android carries the current build number and file size. Match it against your Roblox version before installing. Before comparing features, though, your device already narrows the list.

What Executor Should I Use for Roblox?

Pick by device first, then by key and price. A phone executor will not run as a Windows program, and no Windows executor installs on a phone, so the device rules out half the list before anything else matters.

On an iPhone, Delta installs as a sideloaded IPA, and the Delta Executor iOS install guide walks through both the computer-free and the PC route. Phone players then face a second choice, because Codex and Arceus X are the two apps people weigh against Delta.

Delta vs Codex

Delta wins on build freshness and on its test result. On 20 October 2026, Delta's newest Android build (2.743) matched Roblox for Android, while Codex's newest public build, 2.731, was 12 behind.

That gap matters more than any feature list, since an executor only attaches while its build matches the Roblox build on your phone. Both apps are modified copies of the Roblox app and both are free with a key, but only Delta still has a working iPhone download.

Notice the tracker row: it shows Delta on an older build than Codex, the reverse of the real public builds, because trackers update mobile entries months late. Codex's three failed sUNC checks cover signal and event functions (replicatesignal, getconnections) and custom audio assets, so scripts that lean on those break first. Delta's free key length is still unpublished, and the Delta key duration guide explains how to see the time left on yours.

Delta vs Arceus X

On Android the two are close, and Arceus X NEO was actually the fresher build in mid October 2026. On iPhone, Delta is the only one of the two you can download.

SPDM Team, which makes Arceus X, publishes its current build numbers as small text files in a public GitHub repository. In mid October the NEO Android file read 2.742.1059, the same as Roblox for Android, while the NEO iOS and V5 iOS files read "Updating...". Its V5 notice said purchases were "temporarily unavailable" while the stores are updated. Arceus X is also missing from the main status tracker, so it has no public sUNC result to compare.

Some comparison pages still describe Arceus X as keyless. Its own install steps tell you to "complete key system" before loading your first script, so NEO is free but not keyless.

Delta Premium costs about $7 to $8 for 30 days at the stores Delta lists, and the Delta Premium key breakdown compares free and paid keys in detail. With the phone apps covered, the PC side of the list works very differently.

What Is the Best Roblox Executor for PC?

On a Windows PC, Xeno and Solara are the free native options and Wave is the paid one. Delta has no Windows build, so the only way to run Delta on a Windows PC is the Android app inside an emulator.

That route has a real cost. Roblox's anti-cheat message list says emulators are refused for any account that lacks edit access to the place, and it tells players to switch to a real phone or tablet. If you still go that way, the best emulator for Delta comparison scores BlueStacks, MuMu Player and LDPlayer on exactly that problem.

Xeno vs Solara

Solara runs more scripts: it passed 51 of the 86 sUNC checks against Xeno's 35. Both are free, both skip the key system, and both are external, which means they work from outside the Roblox process.

The failed checks tell you which scripts will break, and they are a better guide than the headline percentage. Both signed result pages show this split:

So a simple hub that only loads a menu and draws ESP runs on both, while anything that auto-clicks prompts needs Solara at minimum. Scripts built on hooks need an internal executor such as Wave or Delta, and on an external one they usually stop with an "attempt to call a nil value" error. Solara's own FAQ says the same in plain words: most popular scripts run, some will not. The Roblox executor explainer covers why internal and external tools differ. One more Solara detail: it says it has no official Discord right now, so any server calling itself Solara's official one is not run by its team.

Is Wave Worth Paying For?

Pay for Wave only when a free external executor fails the script you need, usually a script that hooks functions. Wave costs $4.99 for 7 days, $16.99 for 30 days or $39.99 for 90 days, and its pricing block states that features do not change between plans.

Wave sells one Windows client and nothing for phones, whatever older lists claim. The tracker notes that a different team now develops it, and its note on Wave reads "Last banwave: May 26", so paying buys script support, not safety.

What Happened to KRNL?

KRNL no longer comes from its original team. It was a well-known free executor before Hyperion anti-cheat reached the Windows Roblox client in 2023, then returned in early 2025 as an Android scripting app.

By January 2026 the website used for that comeback showed a parking page. The domain's registrant is now Roblox Corporation, with the record last changed in December 2025. Any "KRNL 2026" download therefore does not come from the KRNL team, so skip any page that still offers a KRNL download button.

Older lists suffer the same problem. Synapse X, once the best-known PC executor, shut down in 2023, which is why a 2021 ranking is not a guide to what works today.

What Is the Best Free Roblox Executor?

On Windows, Solara is the best free pick if you want no key at all: no payment and the higher sUNC score of the two keyless PC options. Of the 25 Windows executors on the tracker in October 2026, seven were free, and only Xeno and Solara needed no key. On phones, Delta, Codex and Arceus X NEO are all free, but each one asks for a key.

As of October 2026 Delta has no keyless version, so the Delta keyless explainer is worth reading before you trust any file sold as "no key Delta". For the free route, the free Delta key steps show which buttons on the key page are real and which are ads.

Delta Executor Alternatives

On a phone, the realistic alternatives to Delta are Codex, Arceus X and Vega X, and all three need a key. On a PC, two free executors that do ask for a key now beat Solara on sUNC. These names show up in other ranking lists and in YouTube comments, and here is where each one stands:

Vega X has the same problem as Codex: its build sits several Roblox updates behind, so it will ask you to upgrade. Fluxus and Swift have no current build from any primary source, so a page offering a 2026 download of either deserves the same caution as the KRNL copies above. A tracker entry only shows that a build exists, not that every file using the name is clean.

What Roblox Executors Are Working Now?

In mid October 2026, a public tracker marked Xeno, Solara and Wave as updated for the current Roblox build. On phones, Delta caught up with Roblox for Android (2.744.1081) on 20 October with 2.743 but stayed two behind on iPhone. Codex's Android build was twelve behind, and Arceus X NEO listed an Android build that matched.

PC executors catch up fastest. When Roblox pushed a new Windows client on the evening of 15 Oct 2026 (UTC), Xeno and Wave had matching builds about 3 hours later and Solara about 5 hours later. Phone executors move slower, because each Delta or Codex build is a full modified copy of the Roblox app. On iPhone, Roblox moved to 2.743.1136 on 15 Oct, while Delta's iOS download page still linked the 2.741 IPA a day later.

An executor works only while its build matches your Roblox build, so compare both numbers before you install anything. Until a matching Delta build ships, an "upgrade" prompt on Android is expected rather than a fault, and the Delta upgrade error fix shows which build pairs with yours. When the app fails for other reasons, the is Delta Executor down check tells you whether the problem is on your side or a wider outage. If Delta is up but still fails, the Delta Executor not working checklist finds the broken step.

sUNC Scores Compared

Source: the signed sUNC result page linked from each tracker entry.

sUNC checks whether an executor's script functions actually behave correctly, not merely whether they exist. From version 2 on, the test script refuses to run anywhere but sUNC's own testing place, and the server signs every result so edited copies get caught. It took over from UNC, whose GitHub project was archived in 2024.

The dates matter: a score is one build tested once. Xeno's 40% comes from version 1.3.30 while the tracker now lists 1.3.60, and both mobile scores at 2.1.0 ran on an older, shorter test list. A higher score means more scripts can run but says nothing about ban risk. The guide to what level executor Delta is explains what Level 7 and Level 8 labels actually mean.

Which Roblox Executor Is Safest?

None of them is safe for your account. In October 2026, the public status tracker flagged every executor here that it lists (Delta, Codex, Xeno, Solara and Wave) as "detected". Roblox's Cheating and Exploiting help page calls exploiting a Terms of Use violation that "will lead to the deletion of an account".

Roblox can suspend or terminate accounts for it, including alternate accounts, and you can lose Robux and items with them. Mobile bans and warnings also spread among players in May 2026, though Roblox has not confirmed a wave. The Delta ban risk guide breaks the risk down by action and explains the limits of using an alt account.

The download itself is the second risk, and it hits PC players hardest:

• Fake Xeno and Solara copies. Fake "undetected Xeno" downloads, spread through Discord, gaming forums and hijacked accounts, carried password-stealing malware in 2026. Fake Solara copies circulated on social media earlier, and one ransomware strain posed as a Solara executor.
• Look-alike domains. Solara names four official domains on its site and says anywhere else is not them, with the download passing only through Linkvertise or LootLabs. A file from a YouTube description or a fifth domain is not Solara's.
• YouTube "free executor" links. Roblox warns that many exploits are scams built to install keyloggers and other password stealers. Survey lockers, password-protected zip files and "turn off your antivirus" advice are the usual signs.
• "False positive" claims. Never switch off security software because a download page says the warning is a false positive.

Is Delta a Good Roblox Executor?

Yes, if you play on Android or iPhone. Delta runs natively on both, it is free with a key from website tasks, and its public builds stay close to Roblox's. On a PC it is a weak fit, because it only runs inside an Android emulator, and the Delta Executor platform guides list the setup for each device.

That Discord count is the real Delta Dynamics server, and the Delta Discord invite check shows how to tell it apart from the copies.

FAQ

Conclusion

For phones, Delta is the executor to start with: native on Android and iPhone, free with a key, and the only mobile option with signed sUNC results on both. On Windows, Solara is the best free choice and Wave is the paid step up when a script needs function hooks. Once you have the right app installed, the guide to running scripts in Delta takes you from paste to execute on any device.
