SQL Explorer for Students — Learn SQL Free, No Setup

Learning SQL shouldn’t require setting up PostgreSQL, configuring Docker, or paying for a cloud database. PondPilot gives you a SQL environment in your browser — bring your own data and start practicing.

No Setup Required

Every SQL course starts with 30 minutes of installation instructions. Skip all of it:

  1. Open app.pondpilot.io
  2. Drop a CSV file (or create data with SQL)
  3. Start writing queries

Works on any computer with a browser. Your school Chromebook, your old laptop, your phone in a pinch.

Practice on Real Data

Toy databases get boring fast. Use PondPilot to query data that interests you:

  • Sports stats: Download CSV data from your favorite sport and analyze player performance
  • Public datasets: Government open data, Kaggle datasets, or Wikipedia tables
  • Your own data: Export your Spotify listening history, fitness tracker data, or bank transactions

SQL becomes interesting when the data matters to you.

Full SQL, Not a Subset

Some educational SQL tools only support basic SELECT statements. PondPilot runs DuckDB — you get the full SQL language:

-- Window functions
SELECT
  player,
  game_date,
  points,
  AVG(points) OVER (PARTITION BY player ORDER BY game_date ROWS 4 PRECEDING) as rolling_avg
FROM game_stats.csv;

When your coursework covers advanced topics, PondPilot keeps up.

Great Alongside Any SQL Course

Using PondPilot doesn’t replace your SQL course — it supplements it. Whatever SQL textbook, YouTube series, or bootcamp you’re following, PondPilot gives you a free practice environment.
