Xeno vs Solara Executor
Both are free, keyless Windows executors — but they are not equal. Xeno has 81% UNC vs Solara's 67%. Here is what that actually means for your scripts.
Our Verdict
Xeno wins on script compatibility — its 81% UNC score runs significantly more scripts than Solara's 67%. For users running anything beyond simple scripts, Xeno is the clear choice. Solara wins on download numbers and brand recognition — if you just need the simplest possible tool for basic scripts, both work, but Solara has vastly more tutorial content thanks to 13.6M+ downloads.
UNC Compatibility — The Key Difference
The 14-point gap between Xeno's 81% and Solara's 67% UNC score is not abstract — it translates directly to which scripts will and will not run. Solara handles simple scripts reliably: basic teleporters, speed modifications, click automation. Xeno handles all of those plus a significantly larger range of community scripts including complex auto-farms, detailed ESP configurations, and scripts that make heavier API calls. If you have ever had a script "not work" on Solara, there is a good chance Xeno would run it.
Why Solara Has 13.6M Downloads Despite Lower Compatibility
Solara grew because it was discoverable and extremely simple to use. Newer players searching for their first executor found Solara through YouTube videos and downloaded it without knowing what UNC meant. The download numbers reflect accessibility and timing more than technical quality. For players who only ever run one or two simple scripts in popular games, Solara's 67% compatibility ceiling never surfaces as a problem — which is why millions of users are perfectly happy with it.
Key System
Both are keyless — this is a tie. Neither requires any daily unlock process. If you are coming from Delta or Fluxus and the key system is your main complaint, either Xeno or Solara solves that. The key system is not a differentiator between these two.
Post-Patch Update Speed
Both executors need to update after Roblox patches, and both have roughly similar update timelines. Neither has a clear structural advantage here — update speed for both depends on the responsiveness of their respective development teams. Check each executor's Discord after a Roblox update rather than assuming one is consistently faster.

Xeno vs Solara — FAQ
Is Xeno better than Solara?
For script compatibility, yes. Xeno's 81% UNC score runs significantly more scripts than Solara's 67%. If you run community scripts regularly, Xeno is the better technical choice. Solara has an advantage only in tutorials and brand recognition due to its 13.6M downloads.
Do both Xeno and Solara have a key system?
Neither does. Both are completely keyless — you download, install, and use them without any daily unlock process. This is one of the main advantages of both executors over Delta and Fluxus.
Why does Solara have more downloads than Xeno?
Solara launched earlier and grew through a wave of YouTube tutorial videos that drove massive download numbers. More downloads reflects discoverability and timing, not technical quality. Xeno's 550k+ downloads are growing as the community recognises its higher UNC score.
Can I use Xeno or Solara on Android?
Neither supports Android. Both are Windows-only executors. For Android, Delta or Arceus X Neo are the recommended free options.
What scripts does Solara fail to run that Xeno handles?
Scripts that rely on advanced Roblox API functions above Solara's 67% UNC ceiling — typically complex auto-farms with many moving parts, detailed ESP configurations, or scripts that use less common Roblox function calls. Simple scripts like basic teleporters and speed hacks run fine on both.
