About MultiPost

MultiPost is a browser extension that lets creators post the same content to several social networks in a single click, saving them from copying posts and articles between sites by hand. Its topics point to marketing automation, social media and content platforms.

The code here covers the extension's components that are open source under Apache-2.0. The README explains that the official Chrome and Edge packages are built and published from a separate monorepo and also bundle a proprietary Agent module, and that this repository only maintains source code, without running any release workflows. The project is written in TypeScript, with documentation in several languages.

Because the official extension packages include closed components, treat this repository as the open portion rather than the complete product. MultiPost suits content creators, marketers and small teams that cross-post regularly and want to reduce repetitive publishing work.
