Fast Java heap dump analyzer, that emulates standard Eclipse MAT views with minimal memory in Rust
https://parttimenerd.github.io/hprof-analyzer/ โ// readme
Heap dump analyzer for JVM applications. Generates MAT-parity reports (leak suspects, retained-size breakdown, OQL queries) with peak RSS well below the dump size for dumps โฅ 1 GiB. One binary covers the full workflow: automated reports, interactive analysis, AI-assisted triage via MCP, heap redaction, and Eclipse MAT cache generation. For dumps up to 3 GB there is also a browser version that runs entirely in WebAssembly.
