PondPilot v0.9.0: MotherDuck, DuckLake, Quack, and SQL Linting

May 13, 2026 Polly

PondPilot v0.9.0 adds three new data source integrations — MotherDuck, DuckLake, and Quack — and built-in SQL linting in the editor.

☁️ MotherDuck Integration

You can now connect to MotherDuck cloud databases directly from PondPilot and query them alongside your local data.

How it works

  • Open the datasource wizard and pick the MotherDuck card
  • Paste your service token and run a test connection
  • Connect — your MotherDuck databases appear in the sidebar with schemas, tables, and columns

The extension loads dynamically from ext.motherduck.com, so no special build is needed. Tokens are stored in the encrypted secret store and auto-reconnect on reload. Production now serves the Cross-Origin-Opener-Policy and Cross-Origin-Embedder-Policy headers so SharedArrayBuffer is available for the extension.

🌊 DuckLake Catalogs

The datasource wizard has a new “DuckLake Catalog” source type.

What you can do

  • Paste a .ducklake URL into the “DuckLake Catalog” card
  • The alias auto-derives from the path; a read-only toggle and CORS proxy option sit next to it
  • Tables appear in the sidebar under “Remote Data Sources” and are searchable via spotlight
  • The catalog reconnects automatically on reload

DuckLake catalogs are public URLs, so no credentials are involved. This release also upgrades DuckDB-WASM to DuckDB v1.5.1, which closes the storage-version compatibility issue when opening files created with newer DuckDB releases.

🦆 Quack Protocol

Quack Server is now a first-class data source in PondPilot.

What you get

  • Connect to a Quack server through the datasource wizard with a token
  • The token is stored encrypted; databases attach and reconnect automatically on app reload
  • Quack databases work everywhere local sources do — queries, the data explorer, and comparison tabs

🔍 SQL Linting

The SQL editor now ships with built-in linting via FlowScope.

What this means in practice

  • A new SQL Linting panel in Settings lets you toggle rules on or off and filter diagnostics by severity
  • Disable a specific rule directly from the editor’s context menu
  • Apply Fix or Fix All through Monaco’s code actions for any auto-fixable issue

🐛 Bug fixes

  • Fixed table alignment and theme consistency issues in the data view
