Posthex
Posthex is a social media scheduling and automation tool. Write a post once and publish it to X, Instagram, LinkedIn, Facebook, TikTok, YouTube, Threads, Bluesky, and Pinterest at the same time, or schedule it for a later date from a calendar view.
Posthex includes AI-generated captions and hashtags, a link-in-bio landing page, per-platform analytics, and a team approval workflow so agencies can require client sign-off before anything is published. Accounts connect through each platform's official OAuth login rather than shared passwords, and access tokens are stored encrypted.
A free plan is available (1 connected account, 5 scheduled posts per month). Paid plans unlock more connected accounts, more scheduled posts, the AI features, the bio page, and the team approval workflow.
