}Engineered for Data Processing Everywhere
A zero-compromise workstation combining the industry-standard jq engine with modern Android ergonomics.
Native C jq 1.7.1 Engine
Direct, zero-overhead execution of arbitrary jq expressions. Runs in a dedicated native background thread with full cancellation safeguards and timeout protection.
Visual Pipeline Builder
Tap any key, object, or array in the tree view to automatically generate filters, projections, slices, unnesting, and sort operations without typing manual syntax.
Multi-Mode Data Viewers
Switch instantly between a color-coded Hierarchical Tree Explorer, an auto-formatting Tabular Grid for arrays of objects, and a syntax-highlighted Raw stream viewer.
Versatile Ingestion
Paste clipboard payloads, pick local files via Android Storage Access Framework (SAF), fetch remote endpoints with custom auth headers, or share JSON directly from other apps.
Multi-Document & NDJSON
Full support for Newline Delimited JSON and streaming outputs. Review individual output cards with summary statistics and instant one-tap document copying.
Absolute Privacy
Your proprietary payloads never touch a remote server. Zero telemetry, zero analytics, zero advertising SDKs. 100% private and sandboxed.
