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 — it lets you automate and reuse your entire data prep workflow through the Recipe feature.

Handler's answer:

Handler is focused on TikTok research for app growth, not generic social media management. It helps marketers move faster from “what should we post?” to clear creative direction based on real winning TikToks.

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 — 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.

Handler's answer:

Handler is built specifically for app marketers who want to find what is already working on TikTok. Instead of guessing content ideas, Handler helps teams discover outlier TikToks, understand winning patterns, and decide what to test next.

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.

Handler's answer:

Handler is made for app founders, growth marketers, mobile app teams, indie app builders, and agencies that use TikTok to grow consumer apps.

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.

Handler's answer:

Handler was created because app teams spend too much time manually scrolling TikTok trying to understand what content works. We built it to make TikTok research faster, clearer, and more repeatable for app marketers.
