OPEN SOURCE / LOCAL HEAP ANALYSIS

Find what keeps
memory alive.

Turn a Java heap snapshot into an investigation. Explore retained memory, trace references, query objects, and review the code—without treating a suspect as a verdict.

Host adapters are alternatives. Memory is the default; optional Disk mode reuses verified structures. Terminal commands can run without a browser. Motion is illustrative, not measured timing. No analysis or network request runs here.

A SMALLER PATH TO CLARITY

Start with evidence.
Keep the boundaries visible.

01 / Orient

Understand the snapshot

Start with totals, then separate shallow storage from retained ownership.

02 / Investigate

Follow the evidence

Explore dominators, actual references, object fields, and paths to GC roots.

03 / Ask

Query precisely

Use HeapQL filters, aggregates, joins, and supported subqueries.

04 / Review

Bridge to code

Resolve source through your host. AI suggestions remain proposals to inspect and test.

YOUR DATA / YOUR DECISION

Local analysis.
Optional AI. Explicit limits.

The analysis engine reads your local dump. AI actions and telemetry have separate controls. Metadata can still be sensitive; approved AI fixes send the full source file.

One engine. Different environments.

VS Code, IntelliJ, terminal, browser, and MCP adapters reuse analysis—not every host capability. Setup and limitations are documented separately.
