Questions & Answers

As answered by people managing dataprep.dev and Backlog.

What makes your product unique?

dataprep.dev's answer

Most data tools force you to upload your CSVs to their servers. We don't. We compiled DuckDB into WebAssembly, meaning you get a blazing-fast, database-level engine running entirely inside your local browser tab. It's 100% private and works instantly.

Backlog's answer:

Backlog combines project management with issue tracking and version control in one simple, intuitive platform. Unlike tools that focus on just tasks or just code, Backlog bridges the gap between teams and developers, making collaboration seamless for everyone.

Why should a person choose your product over its competitors?

dataprep.dev's answer

If you try to open a 2GB CSV in Excel, it freezes and crashes. If you use Python Pandas, you have to write code and manage environments. dataprep.dev gives you the power of code (SQL queries, regex, merging 50 files) with a simple drag-and-drop UI, without ever freezing your computer.

Backlog's answer:

Backlog is affordable, built for all skill levels, and designed to be powerful without being overwhelming. Teams can manage projects, track bugs, review code, and collaborate visually (with Gantt charts, Kanban boards, and wikis) all in one place. It’s easier to get started with than many enterprise tools, but it still scales to handle complex projects.

How would you describe the primary audience of your product?

dataprep.dev's answer

E-commerce sellers flattening messy Shopify exports, performance marketers cleaning ad reports, and data analysts who need to anonymize PII (GDPR compliance) before feeding datasets to AI models like ChatGPT.

Backlog's answer:

Our core audience includes software development teams, IT departments, and project managers who need both project visibility and technical depth. At the same time, marketing, design, and business teams also rely on Backlog to stay connected with developers in a shared workspace.

What's the story behind your product?

dataprep.dev's answer

I was trying to clean up a massive, messy Shopify order export. Excel kept freezing, and I absolutely refused to upload sensitive customer emails to random online converters. I got so frustrated that I decided to stop complaining and build a local-first toolkit to solve my own workflow nightmare.

Backlog's answer:

Backlog was created by Nulab, a Japan-based software company, to make teamwork easier and more enjoyable. We needed a tool where developers and non-developers could work together without friction. Since its launch, Backlog has grown into a global product that helps thousands of teams deliver projects more efficiently.

Who are some of the biggest customers of your product?

dataprep.dev's answer

1, Indie hackers and solo founders. 2, Boutique digital marketing agencies. 3, Privacy-conscious data freelancers.

Backlog's answer:

Backlog is trusted by teams at Buzzfeed, Rakuten, and SoftBank, along with thousands of startups, agencies, and enterprises worldwide. Whether it’s a small consultancy or a large global brand, Backlog helps teams of all sizes manage projects with clarity and collaboration.

Which are the primary technologies used for building your product?

dataprep.dev's answer

DuckDB-Wasm is the core data engine handling the heavy lifting. The frontend is built with React/Next.js and styled with Tailwind CSS. It's a modern, serverless architecture.

Backlog's answer:

Backlog's backend is written using the programming language Scala. This robust foundation helps Backlog run smoothly, even when managing large projects or complex tasks.
