Codex Executor APK Download v2.738: Run Roblox Scripts on Android
Codex Executor is a Roblox script executor with ready made game presets, a built in script hub, and a Lua editor for custom scripts. It promises one tap injection with no key system on its current build.
Finding the real Codex download is the hard part. Rival domains all claim to be official, version numbers disagree across pages, and older clone pages still describe a key system the current build says it dropped.
This Codex Executor APK download guide tracks the current v2.738 build from October 2026, explains the version chaos, and shows how to install it safely on Android, PC, and iOS.
Quick Answer
Codex Executor APK v2.738 is the current build from October 2026, with an Android APK of 92 MB, a Windows build of 46 MB, and no key system on the current official page. Download it from the official download page linked below, install it in place of the normal Roblox app on Android, and test scripts on an alt account first.
What Is Codex Executor
Codex Executor is a free Roblox script executor. It attaches to the running Roblox game and loads a mod menu or a custom Lua script inside it, so players can run game presets for titles like Da Hood, Jailbreak, Blox Fruits, and Pet Sim 99.
Unlike raw script pasting, Codex ships presets tuned per game. You open the app, pick your game, and flip toggles for the features you want, or open the Lua editor and load a custom script of your own.
Codex is not affiliated with Roblox. Executors violate Roblox rules, so any executor use can lead to temporary or permanent bans.

- Lua editor for custom scripts alongside preset menus

- Android APK, Windows EXE, macOS DMG, and iOS IPA builds

Codex Version Chaos Explained
Codex version numbers disagree across the web, and that disagreement is the main trap for downloaders. The current official page lists v2.738 from 14 October 2026, while an executor status board lists v2.731.944 from 22 October 2026, and clone pages still push v1.0.0 or v2.741 builds.
Clone pages also disagree about keys. Older pages describe key checkpoints and Linkvertise flows, while the current official page says the build has no key system at all. If your Codex build asks for a key, you are likely on an older or clone build, not the current official build.
Check three things before you install any Codex file: the version number matches v2.738, the download page matches the official domain, and the file size matches the platform build, 92 MB for Android APK or 46 MB for Windows EXE. A mismatch on any of the three means the page is stale or fake.

Common Errors and Fixes
- Attach fails: update Codex and Roblox together, since version mismatch blocks attach.
- Key prompt appears: you are on an older or clone build, so get the current v2.738 build from the official page.
- Install blocked on Android: allow install unknown apps for your browser, then install again.
- Script menu never loads: copy a fresh script link and test one feature at a time.
- Game crashes on execute: close background apps, lower graphics, and test on an alt account.
Safety Note
Executors violate Roblox rules and can lead to bans, and fake Codex pages are common. Never download Codex from a video comment or a Discord attachment, never enter your Roblox password on a download page, and never pay for a Codex key.
