Can I use PlainHub from the CLI?

Yes. Install with npm install -g plainhub, then use the plainhub open command to open files in the browser. You can also specify theme and font size.

Can I use PlainHub from Claude Code?

Yes. Configure it as an MCP Server, and PlainHub launches just by talking to Claude Code or Cursor. No commands to memorize.

Integrations

No need to open a browser. Operate PlainHub from your terminal or AI IDE. PlainHub fits naturally into your developer workflow.

CLI — One command from your terminal

During code review, thinking "I want to check this doc in the browser"? One command from your terminal opens PlainHub.

npm install -g plainhub
plainhub auth --from-gh
plainhub open README.md -r owner/repo

You can also specify theme and font size, making it useful as a shareable team URL.

plainhub open docs/API.md -r owner/repo --preview on --theme light --fontSize 18

CLI Options

Option	Value	Description
`-r, --repo`	owner/name	Repository
`-l, --line`	number	Jump to line
`--theme`	dark/light	Theme
`--preview`	on/off	Markdown preview
`--sidebar`	on/off	Sidebar visibility
`--fontSize`	8-72	Font size
`--lineNumbers`	on/off	Line numbers
`--whitespace`	on/off	Invisible characters

MCP Server — Natural language from your AI IDE

Just talk to Claude Code or Cursor, and PlainHub launches. No commands to memorize.

"Open the README of owner/repo in PlainHub"
"I want to check this repo in the browser"
"Show me the latest commit diff"
"Check authentication status"

Works alongside gh CLI

Already using gh CLI? PlainHub is ready to go. Shared authentication means almost no extra setup.

plainhub auth --from-gh

If gh CLI is "the tool for operating GitHub," PlainHub is "the tool for editing GitHub files." Different strengths, natural to use together.

gh CLI strengths:
  Issue creation, PR operations, repo management, CI checks

PlainHub strengths:
  Document editing, file creation/saving, Markdown preview, AI consultation

For example: check an Issue with gh CLI → fix the related doc in PlainHub → save (Git commit). Seamlessly move between terminal and browser.

Claude Code Integration

Claude Code + PlainHub covers both code and documentation. See MCP Server / CLI sections above for details.

Workflow examples

Code + Docs — Fix code in Claude Code → update docs in PlainHub → both committed to Git
Bug investigation — Investigate the cause in Claude Code → visually review changes with plainhub diff
Team collaboration — Non-engineers write meeting notes in PlainHub → engineers reference them in Claude Code

Claude Code is where you write code. PlainHub is where you write documents. MCP/CLI connects them seamlessly.

Flexible combinations

PlainHub's CLI, MCP, browser, and AI panel all connect to the same GitHub data. Access the same files from any channel — combine them however you like.

Auto-launch PlainHub from a shell script
Embed PlainHub URLs in CI/CD steps for review workflows
Post shared links from a Slack bot via plainhub open
Include PlainHub URLs in GitHub Actions notifications
Analyze in Claude Code → write reports in PlainHub → commit to the same repo

No restrictions on how you use it. If you have GitHub and a browser, it fits into any workflow.
