PostFast is a social media management platform that helps creators and teams plan, schedule, and publish content from one dashboard. It supports 11 platforms, including Facebook, Instagram, Threads, X, LinkedIn, TikTok, YouTube, and Telegram. Users can compose a post once, preview how it will appear on each network, customize captions and media for individual accounts, and schedule content up to a year ahead. The platform also offers a content calendar, analytics, approval workflows, and a social inbox, with tools for importing posts in bulk.

PostFast caters to both hands-on users and teams managing social accounts at scale. Its AI integrations let users create and schedule posts through Claude, ChatGPT, and compatible agents, while an MCP server supports tools such as Claude Code, Cursor, and other MCP clients. Developers can use the public REST API to manage connected accounts, media, posts, and inbox functions. PostFast offers a seven-day free trial without requiring a credit card. The company reports serving creators and teams across 50 countries, with more than 220,000 posts published.
