Download Fluxus Executor
Get the latest version of Fluxus Executor for your device. Choose your platform below and follow the step-by-step install guide.
Before you start: how the free key works
Fluxus is free. To activate the free version you complete a short key verification (about 30–60 seconds) inside the app — tap “Get Key”, finish the verification step, and you receive a key that is valid for 24 hours. There is no payment for the free key. A paid premium option exists only to skip this step; it adds no extra features. We never ask you to disable your antivirus — instead, you can verify the build yourself on VirusTotal.

Download FAQ
Which Android version should I download (ARM64 vs ARM32)?
Most phones from 2018 onward use ARM64. Try ARM64 first; if it doesn't run, use ARM32. You can check under Settings → About Phone → Processor/CPU.
Why does my antivirus flag Fluxus?
It's a heuristic false positive: script executors use code injection, which looks similar to malware techniques. Verify the published VirusTotal scan first, and if you trust it, add a single file-specific exclusion rather than disabling protection.
The download isn't starting. What should I do?
Try a different browser (Chrome is recommended), pause any download-blocking extensions, and make sure you are downloading from this official site.
Is Fluxus free to download?
Yes, Fluxus is 100% free. Free users complete a short key verification every 24 hours. Premium users skip that step, but the free version has no feature limits.
