// Features
A real level 8 executor, not a wrapper
Isaeva implements the full UNC environment, hooks every capability Roblox exposes, and ships a built-in editor + FPS unlocker. No copy-pasting from Pastebin, no key system.
Hyperion / Byfron bypass
Built-in anti-cheat bypass for Roblox Hyperion. No manual injector, no separate bypass tool — Isaeva attaches without flagging the client.
Built-in script editor
Monaco-style editor with Lua syntax highlighting, autocomplete, line numbers, and a saved script library. Switch tabs between scripts, run multiple at once.
Instant attach
Isaeva detects the running Roblox client the moment you launch it. One Attach button, under 3 seconds — no clicking through dialogs.
FPS unlocker included
The 14.3 MB build ships with an integrated FPS unlocker. Toggle it inside the executor — no separate file, no Franken-framerates. Hit the cap you want.
No key · no survey
The default build is keyless. Download, run, attach, execute. No Discord check, no link shortener, no key server. Free forever.

Frequently Asked Questions
Everything you need to know about Isaeva Executor
What is Isaeva Executor?
Isaeva Executor is a free level 8 keyless Roblox script executor for Windows. It supports UNC-compliant scripts, runs the same library as Synapse X, ships a keyless build with no key system, and includes a built-in Monaco-style editor and an integrated FPS unlocker.
Is Isaeva Executor free to download?
Yes. Isaeva Executor is completely free. The standard build is keyless — no key system, no survey, no paid tier, no Discord verification. Every feature is unlocked out of the box.
Is Isaeva Executor keyless?
Yes. The default Isaeva Executor build is key-free. You download, run as administrator, attach, and execute scripts. No Discord verification, no link shorteners, no key server to click through.
Does Isaeva Executor run Synapse X scripts?
Yes. Isaeva is UNC-compliant (Unified Naming Convention). Scripts written for Synapse X, Script-Ware, Fluxus, Oxygen U, and Hydrogen will all load and execute on Isaeva without modification. Dex Explorer, Infinite Yield, universal ESP / aimbot libs, and the rest of the ecosystem all run.
How do I install Isaeva Executor?
Download the ZIP, extract it to any folder using the password 1337, right-click IsaevaExecutor.exe and select Run as administrator. Open Roblox and join any game, click Attach, paste your script, and click Execute. The whole setup takes under a minute.
Does it work on Windows 11?
Absolutely. Isaeva Executor is fully compatible with Windows 11 and Windows 10 (both x64). Add an exclusion to Windows Defender before you run it, since executors are flagged by heuristic engines by default.
Is Isaeva Executor compatible with the latest Roblox update?
Yes. Isaeva ships a hotfix within 18 hours of every Roblox client patch. The current build (2.4.1) supports Roblox 2.674 and later. Check the version on the download card — if you see a version behind, the executor auto-updates the next time you launch it.
Does it work on Mac or mobile?
No. Isaeva is Windows-only. Roblox executors themselves require Win32 process injection, which is not possible on Mac, iOS, or Android. A Mac or mobile build would have nothing to attach to.
Why is my antivirus flagging it?
Executors hook into other processes (the Roblox client) which heuristic antivirus engines always flag by default. If you trust the source, add an exclusion for the folder in Windows Defender before extracting, then run as administrator.
Is Isaeva Executor safe?
The build is signed and shipped from a single direct download. We recommend downloading only from isaeva-executor.com to avoid fake copies. Scanned with ClamAV and SHA256-verified on every release.
