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.

Another difference is that in .NET Core, we can integrate with OpenAPI out of the box (it is part of the framework), while in Symfony, an API-based application with OpenAPI features is only available using a third-party toolโthe API Platform. - Source: dev.to / about 2 years ago
API Platform is a great tool for rapid API development, but it has a lot of not-so-well-documented features which can sometimes lead to confusion. Playing around with a new project of mine I've stumbled into one: tests were failing for my validation assertions of endpoints' responses! - Source: dev.to / about 2 years ago
Technically API Platform is not part of Symfony. Although, they are both French. ๐. - Source: dev.to / over 2 years ago
Probably API-platform. The website is down at the moment, but: https://github.com/api-platform/api-platform It's Symfony based (and plays nice in that ecosystem), also allows you to describe entities via Schema org vocab, has a client generator, and comes with docker-compose and helm charts. I've used it extensively to build various headless services. It's really easy to expose annotated Doctrine entities. Source: about 3 years ago
API Platform is a framework for API-first projects, built on top of Symfony components. Let's see how to create a minimal and lightweight starter project in just 5 minutes! - Source: dev.to / about 3 years ago
I use this setup on LeapRows, a browser-based CSV tool I built on Vercel. - Source: dev.to / 5 months ago
