How would you describe the primary audience of your product?

LeapRows's answer:

Marketers and SEO professionals who regularly work with large CSV exports (Ahrefs, Google Search Console, GA4, etc.) and find Excel or Google Sheets too slow or unstable for files with hundreds of thousands of rows.
Engineers and data analysts who find it overkill to spin up a Python environment or database just to do a quick aggregation or data cleanup.

What's the story behind your product?

LeapRows's answer:

LeapRows was born out of two frustrations: the "Python sharing problem" and server costs.

As an in-house SEO specialist, I frequently work with large CSVs exported from tools like Ahrefs, Google Search Console, and BigQuery — often hundreds of thousands of rows. For heavy lifting, I'd reach for Python (Polars), but Python has a steep barrier: environment setup, code adjustments, and a learning curve that made it impossible to share with non-engineer teammates.

Even for myself, I'd often think "do I really need to write Python just for this small transformation?" On top of that, frustrating edge cases — like type inference inconsistencies causing join errors on the same CSV from the same tool — kept piling up.

I wanted something as easy as a spreadsheet but capable of handling millions of rows. That's what LeapRows is.

Which are the primary technologies used for building your product?

LeapRows's answer:

DuckDB-WASM, OPFS（Origin Private File System）

Who are some of the biggest customers of your product?
