multipost-extension

MultiPost is a browser extension designed to reduce the friction of cross-posting. From a single edit, users can push text, images and video content to more than ten mainstream social platforms, including Zhihu, Weibo, Xiaohongshu, Douyin and others. The README states that no login, registration or API key is required, and that the tool is free to use. Two integration surfaces are documented. The Extension API lets a user's own web application call the extension to publish content, while the RESTful API allows scripts or servers to trigger publishing. This makes the project usable both as an end-user browser tool and as a building block for custom publishing workflows. This repository is explicitly described as the Apache-2.0 open-source portion of the extension. The official Chrome and Edge packages are built and published from a separate monorepo that also contains a proprietary Agent module; this repository maintains source code only and does not run release workflows. Users should therefore treat it as a source snapshot rather than the canonical distribution channel. Getting started resources include the official website, documentation, developer documentation, and a companion online article editor for creating and publishing content to multiple platforms. Installable builds are available through the Chrome Web Store and Microsoft Edge Add-ons listings. Community support is offered via Discord, GitHub Issues, email, and Chinese-language channels such as WeChat and Tencent Channel. The README does not detail the internal architecture, supported platform list beyond examples, or technical implementation of the publishing mechanism. It also does not make performance or reliability claims. The primary value proposition is workflow efficiency for content creators who currently republish manually across platforms.
