Hey Product Hunt, I built Crossposter as a free and open-source alternative for people who want to publish across their own social accounts without paying for another hosted scheduling tool or handing over everything to a SaaS dashboard. Crossposter runs locally or self-hosted. You compose once, attach media, check platform limits, then publish now or schedule locally. Your config, uploads, drafts, history, and credentials stay on your machine. It supports X, LinkedIn, Bluesky, Mastodon, Instagram, YouTube, Dev.to, Pinterest, Peerlist, Hacker News, Nostr, and Dribbble. Some integrations use official APIs, and some are local/unofficial flows for personal accounts. The goal is simple: a free, open-source, local-first crossposting tool that gives creators and developers more control over their publishing workflow. I’d love feedback, issues, and feature ideas.
