Data grid
Browse millions of rows
Sort, filter and paginate huge files instantly. Every operation compiles to DuckDB SQL, so the grid only ever holds the page on screen — a 50-million-row file feels like 50.
100% local · no upload · no backend
Explore, query and optimize
Parquet files in your browser
Drix opens .parquet files right in your browser — browse and query them
with SQL, inspect the format, optimize for size and speed, and surface insights.
Powered by DuckDB-WASM, with nothing ever leaving the page.
Five tools for one file
SQL console
Query with DuckDB SQL
Run any SQL against your loaded files, JOIN multiple parquets together,
and save snippets for later. Results render in the same fast grid.
File info
See inside the format
Every byte of Parquet metadata: compression codecs, encodings, row-group layout, column statistics, bloom filters and decoded key/value pairs.
Optimize
Optimize for smaller files and faster reads
Drix deep-scans every column for better compression codecs, encodings and row-group layout, estimates exactly how much space you'd save, then generates ready-to-run Polars or DuckDB code to rewrite the file the better way.
Insight
Understand your data
On-demand column statistics (like pandas describe()), correlation
analysis, data-quality checks and anomaly detection — computed in-browser, with no
notebook required.
And a lot of small things done right
-
Every Parquet type
BOOLEAN through INT128, precision-preserving DECIMAL, UUID/JSON/ENUM, every timestamp unit, and nested STRUCT/LIST/MAP as expandable JSON trees.
-
Real type chips
Column headers show the file's true Parquet logical types — not a JavaScript-runtime approximation.
-
Multi-column sort
Click to sort, shift-click to add a secondary sort, with numbered indicators.
-
Type-aware filters
Text gets contains, numbers get range operators, dates get a picker, booleans get a tri-state.
-
CSV export
Export exactly the rows your current filter and sort describe, in one click.
-
Private by default
Files stay in WASM memory. It works offline once cached. There is no server.
