Questions & Answers

As answered by people managing Decodo and LeapRows.

Why should a person choose your product over its competitors?

LeapRows's answer:

  • Zero setup: No installation, no Python environment, no SQL knowledge required. Just open your browser and drop your CSV.
  • Beyond aggregation: Other tools can query large datasets, but LeapRows goes further โ€” it lets you automate and reuse your entire data prep workflow through the Recipe feature.

What makes your product unique?

LeapRows's answer:

LeapRows is a fully local, browser-based data tool powered by DuckDB-WASM that handles 1M+ row CSV files with blazing speed โ€” no server, no uploads.

  • Recipes: Save your entire workflow and replay it instantly on any new file, eliminating repetitive manual work.
  • Smart Join: Perform VLOOKUP-style joins without any code. Composite key joins across multiple columns are supported out of the box.

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 โ€” 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 โ€” like type inference inconsistencies causing join errors on the same CSV from the same tool โ€” 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๏ผˆOrigin Private File System๏ผ‰

Who are some of the biggest customers of your product?

LeapRows's answer:

  • Currently in Beta with no notable enterprise customers yet.

    My Review of Smartproxy Service

    Smartproxy, in my experience, is a solid choice for heavy-duty web scraping tasks. Been using it for bulk data mining. Their proxy pool's massive โ€“ good for avoiding blocks and captchas. Speed's decent, uptime mostly consistent. Setup? Straightforward. But yeah, pricing's a bit on the higher side, especially for large-scale operations. Overall, Smartproxy delivers, especially for those heavy scraping needs.

    ๐Ÿ‘ Pros:    Ip diversity|Quick data access|Minimal downtime|User-friendly interface:
    ๐Ÿ‘Ž Cons:    Pricey|Some geo-restrictions.|Ometimes slow response.
