ParquetPeek brings Apache Parquet files to life on your Mac.
Native SwiftUI app with three standout features:
- QUICK LOOK — Press spacebar on any .parquet file in Finder and
instantly see columns, types, row count, and compression. No
launch needed.
- FAST VIEWER — Double-click to open. Browse schema with nested
types, view data in a native table, inspect per-column
statistics (min, max, nulls, distinct), and check file metadata.
- EMBEDDED SQL — Full DuckDB engine built in. Write SQL queries
against any open Parquet file. Filter, aggregate, join — all
local, all instant.
Why ParquetPeek?

- Zero subscriptions — one-time purchase, yours forever
- Fully local — your data never leaves your machine
- Lightweight — handles multi-GB files via streaming
- Privacy-first — no telemetry, no account, no cloud
Perfect for data engineers, ML engineers, and analysts who work
with Parquet files daily. Stop opening a terminal to peek at a
file. Press spacebar.
