It doesn't work with local file in Linux. e.g. file:///Home/*/foo.md Please fix it.

Jason Swearingen2013年4月2日

Preview and render Markdown files (.md, .markdown, .txt, .rst, etc.) as formatted HTML directly within the Chrome browser

Install extension → Enable 'Allow access to file URLs' in chrome://extensions → Open any .md/.markdown/.txt file locally or remotely in Chrome → Extension content script automatically detects markdown files and converts them to rendered HTML with syntax highlighting, diagrams, and optional TOC. Users can customize themes and behavior via the popup and options page.

Monetization

No paid features detected

This is an open-source extension (GitHub: volca/markdown-preview) with all features freely available. No payment APIs, subscription gates, license checks, or upgrade prompts exist in the source code. All keyword hits for 'pro', 'license', 'stripe' come from bootstrap.css (progress bars, table-striped CSS classes, MIT license headers) - none relate to paid features. No features are gated behind any payment wall.

Confidence: 100
Payment platform: --
Source: AI / High
Login required: No
Reason: This is a purely local extension that renders markdown files as HTML within Chrome. It uses only local storage (chrome.storage.local) for settings. No authentication flows, login pages, OAuth endpoints, or account creation UI exist anywhere in the source. All keyword hits for 'account', 'auth', 'token', 'session' come from third-party libraries (highlight.js, jquery.js) or CONTRIBUTING.md about GitHub contributions - none relate to user authentication.
