Xeno and Wave represent two different models. Xeno is free and keyless. Wave is a premium paid executor with a higher UNC score. But Wave also has a documented malware problem that makes the comparison less about features and more about trust.
Quick Comparison
| Feature | Xeno | Wave |
|---|---|---|
| Price | Free | $4.99/week |
| Keyless | Yes — no keys at all | Paid subscription required |
| UNC Score | ~84% | 99% (100% sUNC) |
| Detection Status | External, updates after patches | Detected — banwaves reported |
| Malware Risk | Fake sites exist; official source is safe | Multiple confirmed malware variants and stolen accounts |
Where Wave Wins on Paper
Wave's technical specs are genuinely strong. Third-party testing shows Wave passes 86 of 86 sUNC functions, giving it a 100% sUNC score and 99% UNC [citation:2][citation:4]. That is significantly higher than Xeno's reported ~84% UNC and ~40% sUNC. If you need maximum script compatibility, especially for complex scripts that rely on advanced executor functions, Wave is technically superior.
Wave is also actively updated. Its version history shows frequent releases, with the latest build (NEW-1.5.9) matching recent Roblox versions [citation:2][citation:4].
The Problem: Wave's Malware History
Wave's technical strength is overshadowed by its security record. Security researchers at ESET (WeLiveSecurity) published an analysis of Wave Executor documenting that multiple variants distributed under the Wave name contain malware, including information stealers and trojans [citation:12].
The report includes user testimonies from Microsoft Community and Reddit: one user reported their Epic Games and Instagram accounts were compromised after using Wave. Another reported their Steam account was emptied and their Discord began sending scam links, suspecting a keylogger. Others reported malicious software including FileCoder and LummaStealer being downloaded [citation:12].
Technical analysis reinforces these reports. A VirusTotal scan flagged a file named wavetrial.rar as malicious, and a Triage report on a Wave Executor download site classified it as containing trojans [citation:12].
Critical: Wave's official source is also unclear. The WeLiveSecurity report notes there are multiple download sources for Wave, making it difficult to know which is the original and which is infected [citation:12]. This is the same problem that plagues Solara and other popular executors.
Where Xeno Wins
Xeno's advantage is not raw performance — it is clarity and safety. Xeno has a single official source (getxeno.space). Its developer has publicly addressed malware accusations and stated that Xeno is not a keylogger [citation:15]. While fake Xeno sites exist, the official source is unambiguous in a way that Wave's is not.
Xeno is also completely free and keyless. There is no subscription, no weekly payment, and no account required. For users who want a working executor without paying or navigating unclear download sources, Xeno is the simpler and safer choice.
In community discussions, Xeno is frequently recommended as the best free executor, while Wave receives mixed feedback — some praise its stability, others call it "dogshit" and warn about its affiliations [citation:9].
Bottom line: If you need maximum UNC/sUNC and are willing to pay $4.99/week and navigate Wave's documented malware risks, Wave is technically superior. If you want a free, keyless executor with a clear official source and a lower risk of downloading malware, Xeno is the safer choice. Only download Xeno from getxeno.space.
