# grip — Render local readme files before sending off to GitHub.

License: permissive · Maintenance: dormant · Downloads: 98.5K/mo

## What it is and what it does

Grip is a local preview server for Markdown files that delegates rendering to GitHub's own Markdown API. You run it from the command line pointing to a README or other Markdown file, and it starts a web server on localhost that displays the file styled exactly as GitHub would render it. The tool supports live reloading—changes to your file appear instantly in the browser without a page refresh.

It's built on Flask and Werkzeug and depends on Markdown, Pygments, and requests to handle rendering, syntax highlighting, and API calls. You can export previews to standalone HTML files with inline styles, pipe content through stdin/stdout for integration with other tools, or authenticate with GitHub credentials to bypass rate limits. The primary use case is verifying README formatting before committing to a repository.

Use it for:

- Preview a README locally before pushing to GitHub to catch formatting issues early.
- Export Markdown documentation to standalone HTML files with GitHub styling preserved.
- Create a local mirror of a GitHub Wiki and browse it with GitHub's native rendering.
- Pipe Markdown from stdin to preview it without saving to a file first.
- Render user-content Markdown (comments, issues) with repository context for link resolution.

## Worth the install?

AI-flagged interpretation of the facts above — verify before relying.

Grip is a command-line server that renders local Markdown files using GitHub's API, so you can preview exactly how your README will look on GitHub before pushing.

Yes, if you regularly write or edit READMEs and want to verify formatting before committing. The tool is stable, has low friction, and solves a specific problem well. The dormant maintenance status is not a blocker—the package is feature-complete for its narrow scope and has no known vulnerabilities. Install it if you do readme-driven development or maintain documentation; skip it if you rarely write Markdown or are comfortable with GitHub's web editor.

## Install

pip install grip
uv add grip
poetry add grip

## Installing grip

Before you install: Low install friction with a pure-Python wheel. Maintenance is dormant—last release was in October 2023—but the repository remains active with recent commits and 6824 stars, suggesting the tool is stable enough for its narrow use case.

License in practice: MIT license is permissive; you can use, modify, and distribute Grip freely with minimal restrictions.

Quickstart:

pip install grip
cd myrepo
grip
# Open browser to http://localhost:6419/

Requires network access to GitHub's API (api.github.com) unless using an offline rendering branch; unauthenticated requests are rate-limited.

Verify before relying:

- Whether offline rendering branch mentioned in description is available or merged into main releases.
- Current Python version compatibility (requires_python is unspecified in metadata).
