Post Everywhere With One API

Stop maintaining separate integrations for each social network. PostPeer normalizes the differences so you write one integration.

Unified Multi-Platform Posting

Send one request and publish to Twitter, Instagram, YouTube, TikTok, Facebook, Pinterest, Threads, and more simultaneously. Platform-specific formatting is handled automatically.

Rich Media Support

Upload images, videos, carousels, Reels, Shorts, and Stories. PostPeer validates and optimizes media for each platform's requirements before publishing.

Zero OAuth Complexity

Your users connect social accounts through PostPeer's OAuth flow. No need to create developer apps, manage tokens, or handle refresh logic.

Platform-Specific Features

Access native features for each platform — Twitter polls, YouTube tags, TikTok privacy settings, Pinterest board targeting, and more via the platformSpecificData field.

Real-Time Post Status

Get instant feedback on every post. The API returns platform-specific post URLs and IDs so you can track content across all networks.

Built for Scale

From 20 free posts to unlimited. Automatic rate limit handling, retry logic, and queuing so your content always gets delivered.
