Questions & Answers

As answered by people managing LucidChart and dataprep.dev.

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.

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.

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.

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.

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.

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.

  • Architecture Diagraming Tools
    I'm thinking something like a lucidchart.com set up, but also wondering since one project is complete if there is anything that can just analyze an existing codebase and automatically do the work for me. Source: over 4 years ago
  • Anyone use the "/diagram" function in Roam?
    Oh! excalidraw.com is great for quick paper style diagrams. I have used it a fair bit. The roam integration is good. But I always revert back to draw.io because it's open sourced, simple to use and just works :D If you are looking for more, a paid option would be lucidchart.com. Source: over 4 years ago
  • ProCurve Network Admin
    You could try lucidchart.com or draw.io. I have used both. Source: over 5 years ago
  • Interactive Relationship Chart
    Otherwise, you may be thinking about a "mind-map" of sorts... Simply to show relationships? Diagrams.net, lucidchart.com. Source: over 5 years ago
  • Looking for feedback on a design system tool
    What is difference between Yours tool and others like arcentry.com lucidchart.com cloudcraft.co hava.io ? Would be nice to support diagrams as code ( generated from kubernetes states, terraform, pulumi, etc..) Personally I dont think that another diagram tool can beat ^ platforms.
