Schedule Content Across Every Platform

Build scheduling into your product without managing queues, cron jobs, or platform-specific timing logic.

Cross-Platform Scheduling

Schedule the same content to Twitter, Instagram, YouTube, TikTok, Facebook, Pinterest, and Threads in a single API request. Each platform gets the right formatting.

Timezone-Aware Delivery

Pass an IANA timezone (e.g., America/New_York) and PostPeer delivers at exactly the right moment. No UTC conversion headaches.

Rich Media Scheduling

Schedule posts with images, videos, carousels, Reels, Shorts, and Stories. Media is uploaded and validated at schedule time, not delivery time.

Reliable Delivery

PostPeer queues scheduled posts with built-in retry logic. If a platform is temporarily unavailable, the post is retried automatically.

Manage Scheduled Posts

View, modify, or cancel scheduled posts before they're published. Update content, change the time, or remove posts from the queue via API.

Platform-Specific Scheduling

Access native scheduling features — YouTube premiere settings, TikTok privacy controls, Pinterest board targeting — all through the platformSpecificData field.
