Hi everyone,
I built HeapLens, an open-source JVM heap analysis tool that lets developers inspect heap dumps and live JVM memory using a query language called HeapQL.
I’m now trying to understand its real-world adoption and impact from people who have actually installed, tested, or used it.
I’m specifically looking for short usage stories from engineers, backend developers, or performance engineers who have tried HeapLens in any memory debugging or heap inspection workflow.
A useful response would be something like:
-
What kind of JVM app or heap dump you used it with
-
Whether you used it for a real issue, investigation, learning exercise, or team workflow
-
What HeapLens helped you identify, understand, or narrow down
-
Whether you adopted it personally, shared it with your team, or would use it again
-
Any limitation that stopped you from using it further
I’m trying to keep this evidence reliable, so please reply only if you have actually installed, tested, or used HeapLens. Redacted screenshots, GitHub comments/issues, or specific technical notes are especially helpful.

If you’re not comfortable commenting publicly, feel free to DM me. I’m happy to keep usage details anonymous unless you explicitly allow your name to be used.
