Postlia is a social media publishing tool built around one composer, scheduled cross-posting, and a set of free content utilities. It lets users connect social accounts, write a post once, and publish or schedule it across supported networks such as LinkedIn, Bluesky, Instagram, TikTok, Pinterest, YouTube Shorts, and Mastodon.
The product also includes a library of 25+ free tools for tasks like handle checking, caption writing, hashtag generation, bio optimization, and content repurposing. For users building agent workflows, Postlia offers an MCP server and API access so AI clients can draft, schedule, and verify delivery.
