What is Posbly?
Posbly is an API-first social media broadcasting service. Send a single API request and publish content simultaneously across multiple platforms — no monthly subscriptions, no seat pricing, no waste.
Built for Builders
Posbly was designed for developers, AI agents, no-code builders, and automation workflows. Whether you're running a Make.com scenario, a Zapier zap, an n8n flow, or a custom AI agent pipeline, Posbly gives you a clean REST API that just works.
Pay-Per-Post Pricing
There are no monthly fees. You pay only for successful posts delivered through the API. Most platforms cost $0.008 per post. X (Twitter) is $0.015 per post. Transparent and predictable at any scale.
9 Supported Platforms
Posbly supports X (Twitter), Instagram, Facebook, Pinterest, Threads, LinkedIn, Bluesky, YouTube, and TikTok. Each platform is a first-class integration with native support for images, videos, carousels, and scheduling.
Scheduling & Webhooks
Schedule posts up to 30 days in advance. Subscribe to webhooks to receive real-time delivery status for every post. HMAC-SHA256 signed payloads and built-in retry logic ensure reliable delivery.
Works With Your Stack
Posbly integrates natively with Make.com, Zapier, and n8n. Any tool that can make an HTTP request can use the API. Connect your social accounts once through the dashboard, then manage everything via API key.
