Possible disadvantages of Joplin

    Joplin is primarily designed for individual use and lacks extensive collaboration features found in other apps like Google Keep or Evernote, making it less suitable for team-based tasks.
  • No Native Web App
    Joplin does not have a native web app version, which can be a drawback for users who prefer accessing their notes through a browser without installing the desktop or mobile applications.

    Setting up synchronization options can be complex for some users, especially for those who are not familiar with cloud services or network configurations.

Questions & Answers

As answered by people managing Joplin and GapQuery.

What makes your product unique?

GapQuery's answer:

GapQuery connects directly to your AI coding environment via MCP. Instead of browsing dashboards, you query 11 app ecosystems and 35,600+ apps through natural language, discovering market gaps, pricing opportunities, and missing integrations right where you code. It's market research that meets you in your terminal.

Why should a person choose your product over its competitors?

GapQuery's answer:

Most market research tools focus on consumer app stores or require expensive subscriptions. GapQuery is purpose built for B2B app ecosystems like Shopify, QuickBooks, and Atlassian, the platforms where micro SaaS businesses actually get built. It's a one time purchase starting at $29, not a recurring fee, and it integrates directly into Claude Code so insights turn into action immediately.

How would you describe the primary audience of your product?

GapQuery's answer:

Solo developers, indie hackers, and micro SaaS founders who want to build apps for established platforms like Shopify, WordPress, or QuickBooks and want data to validate their ideas before writing code.

Which are the primary technologies used for building your product?

GapQuery's answer:

Laravel 12, Livewire 4, MySQL 8, Python (scrapers), Tailwind CSS, and Anthropic's Model Context Protocol (MCP) for AI tool integration.

What's the story behind your product?

GapQuery's answer:

GapQuery started as a personal tool. I was building micro SaaS apps and kept manually searching app stores to figure out what was missing. I realized the same gap analysis I was doing by hand could be automated: scrape the ecosystems, normalize the data, and let AI surface the patterns. What began as a spreadsheet became a database of 35,600+ apps across 11 ecosystems.

  • 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 / 3 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 / over 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
