Crossposter is a free, open-source, self-hosted tool that lets a creator compose once and publish or schedule posts across X, LinkedIn, Bluesky, Mastodon, Instagram, and eight other platforms from localhost. It's built for creators who publish the same content everywhere and want to avoid a paid social-media scheduling SaaS.
