Features and specs

What each product offers, as listed by its team.

HackMD 5 features
PlainHub.dev 9 features
  • Collaboration
    HackMD offers real-time collaborative editing, which allows multiple users to work on the same document simultaneously. This feature enhances teamwork and productivity, especially for remote teams.
  • Markdown Support
    HackMD is built around Markdown, providing a simple yet powerful syntax for formatting documents. Markdown compatibility makes it easy to create well-structured content with minimal effort.
  • Version Control
    The platform includes version history, allowing users to track changes, revert to previous versions, and compare different iterations. This feature ensures that work is not lost and can be systematically reviewed.
  • Integration
    HackMD integrates with popular platforms like GitHub, GitLab, and Dropbox, allowing for seamless workflow integration. This makes it easy to incorporate HackMD into existing development and project management processes.
  • Accessibility
    HackMD is a web-based tool, meaning it can be accessed from any device with an internet connection. This ensures that users can collaborate and edit documents from different locations and devices.

Possible disadvantages

  • Limited Offline Support
    Since HackMD is primarily a web-based tool, it offers limited functionalities when offline. Users may face challenges accessing and editing documents without an internet connection.
  • Subscription Model
    While HackMD offers a free tier, advanced features and greater collaboration capacities are locked behind a subscription model. This could be a disadvantage for users and small teams with limited budgets.
  • Learning Curve
    Users unfamiliar with Markdown or collaborative editing tools may have a learning curve to overcome. This could affect initial productivity and user experience.
  • Data Privacy
    As a cloud-based service, users may have concerns about data privacy and security. Sensitive information stored on the platform could potentially be accessed by third parties or become vulnerable to data breaches.
  • Performance Issues
    Under heavy usage or with large documents, some users might experience occasional performance issues such as lag or slow syncing. This can disrupt the workflow and collaborative efforts.
  • 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 HackMD 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.
