Questions & Answers

As answered by people managing Joplin 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.

  • Show HN: Files.md โ€“ open-source alternative to Obsidian
    What is this providing over similarly Markdown based open source note taking applications like Joplin? (https://joplinapp.org/) I've been a huge fan of the fact that my backend sync infrastructure is my own self-hosted S3 bucket with local clients handling the presentation layer. - Source: Hacker News / 2 months ago
  • An Introduction to Obsidian
    Shout out to Joplin (https://joplinapp.org/), which I use on a daily basis. It does most of what Obsidian does but has a free sync version where you just use your cloud drive as the storage. The main thing missing, from what I've found, is that it does do the "notes mind map". But I never really found that useful. - Source: Hacker News / 4 months ago
  • Ditching Obsidian and building my own
    I use Joplin (https://joplinapp.org) on mobile and pc(windows and Linux). Joplin has a free encrypted sync via OneDrive. - Source: Hacker News / about 1 year ago

  • Ask HN: What Are You Working On? (February 2025)
    Thanks! I built the editor using Tiptap (https://tiptap.dev/) does something similar. I'll think about this for sure, especially since I've been thinking of making it possible to save and read local files. If you'd like to try Gorby, send me an email and I'll be happy to give you a free license code :). - Source: Hacker News / over 1 year ago
