LazyRelay

LazyRelay schedules social posts across 18 distribution platforms plus WhatsApp: Facebook, Instagram, TikTok, Pinterest, YouTube, LinkedIn, Threads, Mastodon, Bluesky, Telegram, Discord, Tumblr, WordPress, dev.to, Hashnode, Lemmy, Slack and X. After publishing, it checks with the platform that each post is really live (Proof-of-Publish), so a post is not marked done just because an API call was accepted.

There is a free plan with no card, and AI agent access through an MCP server with 27 tools is included on every plan.
