MultiPost — One-Click Multi-Platform Publishing

Cross-posting is tedious. MultiPost makes it fast.

If you’ve ever copied content into five different social platforms, resized images, reformatted text, and wrestled with multiple logins, you know how time-consuming multi-platform publishing can be. MultiPost is a browser extension built to remove that friction: write once, publish everywhere.

What It Does

MultiPost is a browser extension and ecosystem for publishing content to multiple social media platforms with one click. It bundles a set of tools to help creators, marketers, and developers push content across more than ten mainstream platforms (the repo mentions support for platforms such as Zhihu, Weibo, Xiaohongshu, Douyin/TikTok, and others).

Post your content (text, images, videos, etc.) to multiple platforms with one click — no login, no registration, no API Key required. Completely free.

Core capabilities

  • One-click publishing to 10+ mainstream platforms.
  • Two API interfaces: an Extension API for web apps and a RESTful API for scripts or servers.
  • Content analytics to track performance of posts across platforms and websites.
  • Built-in scraper tools: reader (export to Markdown/JSON), SERP collector, and social media content fetcher.

Who It’s For

MultiPost is designed for a range of users who publish content across multiple channels:

  • Content creators who want to write once and publish everywhere without repeating work.
  • Social media managers who need to synchronize messaging across platforms.
  • Developers and technical teams who want to integrate a browser extension into web apps via the Extension API, or automate publishing using the RESTful API.
  • Marketers and small businesses looking to reduce overhead when distributing promotional content.

Skill-level: the extension supports non-technical users through its UI and an online editor, while offering APIs for developers who want programmatic integration.

How It Works

MultiPost combines a browser extension, a companion online editor, RESTful endpoints, and scraper utilities to provide a full publishing workflow:

Architecture & workflow (high-level)

  • Browser extension: runs in Chrome/Edge and provides the main UI for composing and sending posts to multiple platforms in one action.
  • Extension API: an interface you can call from your own web application to leverage the extension’s publishing capabilities directly within a custom workflow.
  • RESTful API: allows scripts or servers to send content to MultiPost for distribution (suitable for automation).
  • Article Editor: an online Markdown editor (MultiPost Article Editor) that integrates with the publishing flow so you can compose, preview, and publish from the web.
  • Scraper & reader: reads page content and exports it as Markdown or JSON; also fetches search engine results and social media content to support sourcing, republishing, or analytics.
  • Analytics: tracks content performance across platforms, providing monitoring for websites and social accounts.

Key technologies

  • Browser extension technologies (Chrome/Edge add-on support).
  • RESTful APIs for server/script integration.
  • Web-based Markdown editor for content creation.
  • Scraper utilities returning Markdown/JSON and SERP/social data.

Notes: The repository and documentation linked above contain the exact build and installation steps, as well as API usage examples. Because the README provides high-level pointers rather than step-by-step build commands, follow the docs at docs.multipost.app for details on using the Extension API or RESTful API.

Basic usage examples

  • Compose content in the MultiPost Article Editor and publish to selected platforms with one click.
  • Call the Extension API from your web application to surface MultiPost’s publish dialog inside a custom CMS (see documentation for integration details).
  • Use the RESTful API from a script or server to automate scheduled multi-platform posts (refer to the documentation for endpoint and authentication details).

Key Features

  • One-click multi-platform publishing for text, images, and videos.
  • No login or API keys required for basic publishing workflows.
  • Two integration paths: Extension API for client-side integrations and RESTful API for server-side automation.
  • Content scraping: reader export to Markdown/JSON, SERP and social scraping utilities.
  • Analytics: cross-platform performance tracking for posts and websites.
  • Free and open source — repository, online editor, and documentation are openly available.

Why It’s Worth Trying

MultiPost directly addresses the time sink of manual cross-posting. The combination of a browser extension, an editor, and APIs means both non-technical users and developers can benefit. The project lists official website and documentation links, an online article editor, and browser store listings for Chrome and Edge — so you can try it without a complex setup.

Useful for anyone who values speed and consistency when publishing across many social channels.

The repository also shows community-friendly signals: license badge, commit activity badge, Chrome Web Store version/users/last-updated indicators, and a star-history chart for related repositories. The project is sponsored in part (CDN and security) by Tencent EdgeOne and lists DartNode as a sponsor for open source hosting.

Final Thoughts

MultiPost is a pragmatic project for anyone who publishes the same content across multiple platforms. Its value lies in saving time and centralizing publishing workflows: a browser extension for quick usage, an online editor for content creation, and APIs for deeper integration and automation. If you publish frequently, especially across Chinese and global platforms like Zhihu, Weibo, Xiaohongshu, and Douyin/TikTok, MultiPost is worth a look.
