First of all, I apologize for making the download path long. I want to give you a community explanation with the source.
Why should we use this code editor? The high speed of this code editor can execute 100 thousand lines of code with less than 200 MB of RAM and most importantly, it has 100 algorithms to detect dangerous and unoptimized code and can detect obsolete code, which are the main reasons to download this code editor.
The next point is the outline section, which shows you the functions so that you can see the skeleton of your project.
If you have any ideas or suggestions, you can tell me here so that I can read and implement them.
Roblox Luau Script Analyzer
A powerful static code analysis system for Roblox Studio / Luau that analyzes scripts line by line and identifies issues related to Performance, Best Practices, Deprecated APIs, Potential Errors, Security Risks, and Obfuscation.
Performance & Best Practices
The analyzer checks for the following patterns and potential issues:
Detects the use of
wait()and recommendstask.wait()
Detects infinite
while true doloops that do not containtask.wait()orwait()and may cause excessive CPU usage or freezing
Detects
repeat ... until falseloops without a yielding mechanism
Checks Event Connections created with
:Connect()that may not have a corresponding:Disconnect()
Detects deeply nested and direct Instance access and recommends
FindFirstChild()to reduce potentialnilerrors
Recommends using
game:GetService()instead of directly accessing services such asgame.Workspaceandgame.ReplicatedStorage
Recommends
ipairs()for array-like Tables instead ofpairs()
Detects the use of
error()without appropriate error handling such aspcall()/xpcall()
Analyzes
Instance.new()usage and recommends caching/configuring the Instance before assigning itsParent
Checks
TweenInfo.new()calls for missing or unspecified parameters
Analyzes
UserInputService:BindAction()usage and recommends more appropriate input-handling approaches where applicable
Checks
MeshPartcreation and warns about potential Collision configuration issues
Detects expensive
math.*operations inside loops
Detects
Promise.new()usage and recommends handling failures with:Catch()
Recommends
PathfindingServiceinstead ofWorkspace:MoveTo()for Humanoid movement where appropriate
Detects the use of
BodyVelocityonHumanoidRootPart
Checks
Partobjects created withInstance.new("Part")whenCanCollideis not explicitly configured
Detects direct
CFrameassignments and may recommendTweenServicefor smoother movement
Checks direct use of
Touchedon Humanoids
Detects multiple
string.split()calls on the same line and recommends splitting once and reusing the result
Checks Debounce variables and recommends making them local where appropriate
Detects UI element access without
nilchecks
Detects multiple
task.wait()calls on the same line
Recommends
task.spawn()instead ofspawn()
Recommends
task.delay()instead ofdelay()
Recommends
task.defer()instead ofdefer()
Detects
game:GetObjects()usage and recommends newer API approaches where applicable
Detects
WaitForChild()without a timeout and warns about potential Infinite Yield
Checks
LoadAnimation()usage before confirming that anAnimatorexistsThis section is directly implemented through a collection of dedicated Performance / Best Practice rules.
Deprecated Roblox API Detection
The analyzer also detects the use of older or deprecated Roblox APIs and syntax, including:
The analyzer also performs dedicated checks for:
Numeric indexing of
Enumvalues
Invalid or deprecated usage of
Instance.new("DataModel")
Various legacy APIs and syntax patterns, including replacement recommendations
Deprecated Roblox APIs are implemented as independent analyzer rules, allowing them to be detected and reported separately.
Security & Obfuscation Detection
One of the major components of the analyzer is the detection of suspicious security-related patterns, exploit indicators, runtime manipulation, and code obfuscation techniques.
The system detects patterns such as:
![]()
debug.traceback
![]()
debug.getupvalue
![]()
debug.setupvalue
![]()
debug.sethook
![]()
hookfunction()
![]()
bit32.*
![]()
os.execute()
![]()
io.popen()
![]()
writefile()
![]()
readfile()
![]()
getgenv()
Global variables named
shared
![]()
loadstring()
![]()
loadfile()
![]()
getfenv()
![]()
setfenv()The analyzer also detects more complex patterns.
Remote Code Execution Patterns
- Detects combinations of
HttpGet()+loadstring()
- Detects
require()combined withHttpGet()
- Identifies code retrieved from remote sources and dynamically executed at runtime
Obfuscation Detection
The analyzer can detect:
- Suspicious use of
select()combined with variadic unpacking (...)
wait(math.random(...))as a potentially suspicious or obfuscated delay pattern
- Extremely long strings containing excessive escape sequences
- Unicode escape sequences such as
\uXXXX
- Hex escape sequences such as
\xXX
loadstring(string.char(...))
pcall(loadstring(string.char(...)))
- Combinations of
__indexandrawget
__calloverrides usingsetmetatable
__metatableoverrides usingsetmetatable
task.spawn()combined withrepeat ... until falseloopsThese checks are designed to identify potential exploit behavior, dynamic code loading, runtime manipulation, and obfuscation patterns.
Important: A security warning does not automatically mean that the code is malicious. These patterns may have legitimate uses, so human review is still recommended.
Context-Aware Analysis
The analyzer does not rely exclusively on isolated line-by-line pattern matching.
For certain rules, the system can analyze:
Lines before the current line
Lines after the current line
Larger sections of the current code block
Structures such as
do ... end
![]()
function ... end
![]()
then ... end
![]()
repeat ... untilThis allows certain warnings to be generated based on the context surrounding the code, rather than simply matching an individual pattern on a single line.
Smart Comment & String Handling
Before executing many of its rules, the analyzer processes the source code to reduce false positives.
It can:
- Ignore the contents of Strings during normal analysis
- Mask single-line comments
- Preserve the original line length so Pattern locations remain unchanged
- Prevent normal rules from triggering on patterns found inside Comments or Strings
However, Security rules intentionally analyze certain patterns on the Raw Line, allowing potentially suspicious patterns hidden inside Strings to still be detected.
Robust Analysis Engine
The analyzer follows a structured analysis pipeline:
- Receives the Luau source code
- Splits the source code into individual lines
- Ignores comment-only lines
- Runs all registered rules against the source
- Provides the appropriate Context to each rule
- Stores every Finding with:
- Line number
- Warning message
- Category
- The relevant source code
- If a Rule throws an Exception, the entire Analyzer does not stop. The problematic rule is safely skipped and analysis continues with the remaining rules.
As a result, every detected issue can be reported with:
Line Number + Message + Category + Code
Warning Categories
All Findings are organized into three primary categories:
Style / Performance / Best Practice
Deprecated API
Security / Obfuscation
