USP – Write once in Markdown, post everywhere
USP is a tool that lets users write content in Markdown and publish it to multiple platforms like WordPress, Medium, Dev.to, Telegram, and LinkedIn simultaneously. It supports features such as automatic slug generation, front-matter metadata, and MediaWiki-style image formatting.
Background
- USP (Universal Social Publisher) is a command-line tool that lets users write a post in Markdown and then publish it to multiple platforms (Bluesky, Mastodon, Telegram, Twitter/X, LinkedIn, Instagram, Threads, WordPress, and email) from a single command.
- The creator, Adam Arutyunov, is an independent developer; the project is open-source under the MIT license, meaning anyone can freely use, modify, and redistribute it.
- This kind of cross-posting tool is useful for people who maintain a presence across several social networks — a common workflow challenge for writers, journalists, marketers, and community managers — and avoids the need to manually copy-paste or reformat content for each platform.
- The tool is still early-stage: its README warns that it's "a work in progress" and not yet stable, and the core logic is roughly 200 lines of Rust code. It requires API keys or tokens for each platform, which the user must set up themselves.
