Project Overview
MultiPost is an open-source browser extension designed for content creators, supporting one-click synchronization of text, images, videos, and other content to over 10 mainstream social platforms such as Zhihu, Weibo, Xiaohongshu, and Douyin. No registration or API key is required, it is completely free and cross-platform compatible (supports Chrome/Edge browsers). The project has gained active community support on GitHub, providing multilingual documentation (Chinese/English/Japanese/French/Korean), and aims to alleviate the repetitive work pain points of multi-platform publishing, allowing creators to focus on the content itself.
Main Highlights
✨ Core Features Disrupting Traditional Publishing Processes
- • Minimal Operation: Edit once to synchronize and publish to all bound platforms, saving time on repeated logins and format adjustments
- • Full Type Support: Text, images, videos, and Markdown content seamlessly adapt to the format requirements of each platform
- • No Barrier to Use: Runs purely on the browser side, no server configuration needed, full functionality available upon installation
🛠️ Developer-Friendly Dual API System
- 1. Extension API: Allows direct invocation of extension capabilities in your own web applications, enabling embedded multi-platform publishing
- 2. RESTful API: Supports remote calls from scripts/servers, meeting automation and bulk publishing needs (Typical scenario: bulk synchronization of product reviews to Xiaohongshu/Douyin from e-commerce platforms, one-click distribution of corporate PR materials across all platforms)
📊 Data-Driven Content Optimization
- • Built-in analytics tools track publishing effectiveness across platforms (views, interaction rates, dissemination pathways)
- • Supports monitoring of your own website and social media account data, generating visual comparison reports
🕸️ Intelligent Content Crawling Capabilities
- • Web Reader: Automatically parses web content and outputs in Markdown/JSON format
- • Search Engine Crawler: Batch retrieves search result data from engines like Google/Bing
- • Social Media Collection: Targeted crawling of historical content from specified accounts (must comply with platform rules)
