PostPeer

PostPeer is a unified social media API for developers, SaaS builders, agencies and AI agents that need to publish content programmatically. Instead of integrating each platform's own API, OAuth flow and token refresh, a single request publishes or schedules a post to X, Instagram, YouTube, Facebook, TikTok, Threads, Pinterest, LinkedIn, Bluesky and Google Business. The same connection exposes endpoints for post analytics, comment management with reply, hide and delete, and direct messaging, so software products can offer social features to their own users. It is priced on credits with a free tier, and it was built by developers who had faced the same integration work in earlier products.
