Crossposter: Free, Open-Source Social Publishing from Localhost

I built Crossposter, a free and open-source local-first dashboard for publishing across your own social accounts from localhost.

It lets you compose once, attach media, check platform limits, publish immediately, or schedule posts locally.

Crossposter supports X, LinkedIn, Bluesky, Mastodon, Instagram, YouTube, Dev.to, Pinterest, Peerlist, Hacker News, Nostr, and Dribbble.

The main idea is simple: keep publishing local. Your config, uploads, drafts, history, and credentials stay on your machine instead of inside a hosted
SaaS dashboard.

Run it with:

bash
  npx @apoorvdarshan/crossposter@latest
