Unity Runtime Inspector

Purpose-built for developers, QA, and toolmakers, the Unity Runtime Inspector reveals the runtime serialized state of Unity objects. It enumerates fields, properties, arrays, and nested objects according to Unity serialization rules, capturing type, value, and metadata in a stable snapshot. This enables reasoning about runtime behavior beyond what the standard editor provides.
Conceptually, the tool traverses object graphs with depth controls, handles common collections, and represents references without duplicating data. It emphasizes non-destructive inspection and reproducible results, making it suitable for automated test integration and CI workflows.
Who benefits most includes developers validating scene initialization, QA analysts reproducing sporadic bugs, and plugin authors validating runtime compatibility. Typical use cases are verifying state after scene loads, tracking changes when gameplay events occur, and exporting snapshots for test harnesses.
Unique value comes from deterministic snapshots, support for depth and filter customization, and export capabilities that integrate with automation pipelines. Core features include depth-limited traversal, collection handling (arrays, lists, dictionaries), reference tracking to avoid cycles, and JSON export for tooling compatibility. It complements the editor inspector by providing live runtime visibility without requiring invasive changes to project code.
