About PostBroadcaster
PostBroadcaster is a hosted scheduler that reaches both mainstream networks and the decentralized social web from a single composer. You write a caption, choose your connected accounts, then publish immediately or schedule for later, with the option to tweak the copy for networks that need a different tone or length.
Supported destinations include X, Instagram, Facebook, LinkedIn, YouTube, TikTok, Threads, Bluesky, Telegram, Mastodon, Nostr, Pixelfed, PeerTube, Pleroma, Misskey, VK, WeChat, Tumblr, Pinterest and Google Business. Reddit and Hacker News are treated as listening sources rather than publishing targets.
An API lets coding agents and scripts list accounts, publish and schedule over HTTP using the same path as the dashboard, with keys created after signing in. It positions itself as an alternative to expensive suites and signs users in with Google.
