Does your service run fine for two hours and then quietly eat every gigabyte on the box? Restarting it nightly hides the problem without fixing it. Memory leaks rarely announce themselves in a stack trace. They show up as a slow climb on a graph and an out of memory kill at 3am. The Memory Leak Detector reads your code and tells you which part is holding on.
Short answer: Memory Leak Detector replaces the guesswork between a memory graph that climbs all night and the line of code holding the reference. Paste the suspect code and it names the retention and rewrites the fix.
What is Memory Leak Detector?
Memory Leak Detector is a code review tool aimed at one problem: memory that goes up and never comes down. You paste the suspect code and describe the behaviour you see. It answers with a likely root cause, the reference chain keeping the object alive, and a corrected version. It does not attach to your process or take a heap snapshot.
What To Paste For A Useful Answer
The answer tracks the quality of the paste. Include these four things.
- The code you suspect, plus whatever registers or starts it.
- The symptom you can see, such as memory climbing steadily over a few hours.
- The runtime and framework version, since collection behaviour differs between them.
- Anything you already ruled out, so the answer does not repeat your work.
Do not paste a whole file when a hot loop, an event subscription and a cache declaration would do.
How Does Memory Leak Detector Work?
Paste the code and the behaviour into the prompt box. Choose a model from the selector, then open Advanced options and set the language and issue type, which pushes the analysis towards retention instead of general tidying. Press Generate. The result appears in the output card with the cause, the fix and a prevention note. Earlier runs stay in the activity history panel, so a second paste with more context can be compared against the first.
Issue Type, Analysis Depth And Thoroughness
Analysis Depth opens on Standard and the Thoroughness slider opens at 70 percent. These four choices matter most here.
| Option | What it does | Suggested setting |
|---|---|---|
| Language | Applies the right memory model and idioms | Name your language, not Auto-Detect |
| Issue Type | Narrows what the review looks for | Memory Leak |
| Analysis Depth | How far the reasoning goes past the obvious | Deep for anything long running |
| Output | The shape of the answer you get | Root Cause when you want the why |
Explain Root Cause, Provide Fixed Code and Suggest Prevention are on already. Show Test to Reproduce starts off, and it is worth turning on when you need proof the fix worked.
What The Analysis Cannot See
Where it helps
- Listeners and timers that are registered but never removed
- Caches and module level collections that only ever grow
- Closures quietly holding a large object alive
- Plain English on why a reference survives collection
Where it stops
- It cannot measure your process, so it cannot confirm a leak exists
- It only sees the code you pasted, and retention often crosses files
- A confident answer can still name the wrong reference
Confirm it yourself Take two heap snapshots under load, before and after the change, and compare retained size. That measurement is the proof, not the explanation.
EizTools gives every job its own tool instead of one general chat box, all free, with no account and a model you choose per run. Next to the Memory Leak Detector sits the Error Fixer, which is the better starting point when you have a crash and a stack trace rather than a slow climb on a memory graph.
Frequently Asked Questions
Can the Memory Leak Detector run or profile my application?
No. It reads the code and symptoms you paste, then reasons about them. Nothing is executed or measured, so a profiler is still the tool that proves memory is really being retained.
How much code should I paste at once?
Enough to include the suspect and its lifecycle, usually a few dozen lines. A whole file dilutes the analysis, and several files at once tend to produce vague answers instead of one cause.
Does it work on a language without garbage collection?
Yes, and the advice changes completely. Set Language rather than leaving it blank, because a missing free in C++ and a listener never removed in JavaScript are different problems with different fixes.
What changes between Quick, Standard and Deep?
Quick flags the obvious pattern fast. Standard is the default balance. Deep spends more of the answer tracing why the reference survives, which is what a leak that shows up after hours needs.
It found nothing. What next?
Widen the paste to include the caller, raise Thoroughness above the default, and describe the growth curve precisely. If it stays clean, the retention probably lives in a dependency or code you never pasted.
A leak is a patience problem as much as a coding problem, because the evidence arrives hours after the mistake. A named suspect and a reference chain in plain English shorten that gap. Paste the real code, set the issue type, and treat the Memory Leak Detector answer as the hypothesis your profiler then confirms.
