Features and specs

What each product offers, as listed by its team.

Obsidian 6 features
PlainHub.dev 9 features
  • Local-first
    Obsidian stores your notes locally on your device, giving you full control over your data and enhancing privacy.
  • Markdown Support
    Obsidian uses Markdown, making it easy to format text and compatible with many other text editors and tools.
  • Bidirectional Linking
    You can create bidirectional links between notes, which helps in building a knowledge graph and navigating related information more easily.

Possible disadvantages

  • Learning Curve
    Obsidian can be complex and overwhelming for beginners due to its extensive features and customizable nature.
  • Sync Limitations
    While local-first is great for privacy, it requires additional steps or third-party solutions for syncing across devices.
  • No True Real-time Collaboration
    Obsidian lacks native real-time collaboration features, making it less suitable for collaborative work compared to cloud-based solutions.
  • Limited Mobile Features
    The mobile version of Obsidian, while functional, is not as robust as the desktop application, potentially hindering productivity on the go.
  • Dependence on Plugins
    Many advanced features require the use of third-party plugins, which could lead to compatibility issues and reliance on community support.
  • Performance on Large Vaults
    Performance might degrade with a very large number of notes or complex graphs, impacting usability.
  • GitHub, without the git
    Edit Markdown and plain-text files in your GitHub repos from a browser or phone; every save is a Git commit.
  • Your Claude Code, wired in
    Your own Claude Code, from any browser or your phone, by text or hands-free by voice. No API key needed.
  • A shared ledger for agents and people
    Agents post progress notes and decision cards in your repo; you approve or decline from PC or phone.
  • Search across all your repositories
    One search box for every repo you've connected.
  • An AI panel you stay in control of
    It proposes edits you review before they are applied.
  • Organize it like a drive
    Folders, drag and drop, and previews for images and PDFs; one commit each.
  • Safe by design
    History, diffs, and a compare screen; PlainHub asks instead of silently overwriting.
  • MCP server and CLI
    On npm (plainhub), listed in the MCP Registry. Tested with Claude Code.
  • Your files stay in your GitHub
    PlainHub's servers don't store them; you choose which repos the GitHub App can access.

Questions & Answers

As answered by people managing Obsidian and PlainHub.dev.

What makes your product unique?

PlainHub.dev's answer:

Your files live in your own GitHub repository, not on our servers, and every save is a Git commit. On top of that editor, PlainHub connects to the Claude Code running on your own PC, so you can use it from a browser or your phone and approve its proposals from anywhere.

How would you describe the primary audience of your product?

PlainHub.dev's answer:

Developers who use Claude Code and keep notes, docs, or plans in GitHub, and want to read, write, and approve from a browser or phone.

Which are the primary technologies used for building your product?

PlainHub.dev's answer:

Plain JavaScript, CodeMirror, marked, DOMPurify and Mermaid in the browser; Cloudflare Pages and Functions; a GitHub App on the GitHub REST API; and a Node.js CLI and MCP server (Model Context Protocol SDK).

What's the story behind your product?

PlainHub.dev's answer:

I jot down ideas on my phone on the train, and my notes keep getting longer. Many note apps can get slow once a single note grows very long. I wanted plain text files in my own GitHub that stay fast at any length and open on any device. My main note is now about 26,000 lines and still opens quickly. Later I connected it to the Claude Code on my home PC, so I can search my notes and past logs from my phone.

Why should a person choose your product over its competitors?

PlainHub.dev's answer:

Choose it if you want your notes and docs in a GitHub repo you own, with full history, and you want to write them from any device without using git. It also suits people who already use Claude Code: your agent can search and edit the same repo, and its decisions stay in Git.

    For note-taking, I recommend Obsidian. It's lightweight, has a large community, and offers plenty of useful plugins. I use the Timekeep plugin myself, which helps me connect tasks with the time spent on them. - Source: dev.to / 24 days ago
