What is a HEAPSNAPSHOT file?

HEAPSNAPSHOT files mostly belong to Chrome DevTools.

HEAPSNAPSHOT files are JSON-based dumps that record the state of JavaScript memory during a run. They are generated by Chrome DevTools when you take a memory snapshot.
These files capture details such as object allocations and reference chains.
Key uses include:

Inspecting memory allocations
Detecting memory leaks
Analyzing object references

FilExt.com note: To view a HEAPSNAPSHOT, open Chrome DevTools and use the Memory panel to load the file. More details can be found at Chrome DevTools documentation.

How to open HEAPSNAPSHOT files

You need a suitable software like Chrome DevTools to open a HEAPSNAPSHOT file. Without proper software you will receive a Windows message "How do you want to open this file?" or "Windows cannot open this file" or a similar Mac/iPhone/Android alert.

A *.HEAPSNAPSHOT file stores a snapshot of the JavaScript heap memory. It's saved in a JSON format and contains information about JavaScript objects and their relationships, allowing developers to analyze memory usage and identify potential memory leaks. This snapshot is created at a specific point in time and reflects the memory state of the application at that moment. The snapshot includes details about object sizes, references between objects, and the call stack that led to object allocation. Analyzing heap snapshots can help optimize memory consumption and improve the performance of web applications. This file format is classified as Debugging/Profiling.
