Letmepost
Publish and schedule posts to 8 platforms with one API
Letmepost is an open-source social media API that lets developers and AI agents publish and schedule content across X, Instagram, Facebook, Threads, LinkedIn, TikTok, Pinterest, and Bluesky from a single endpoint. It enforces robust preflight rules, supports idempotency, signed webhooks, and multi-account fanout for reliable delivery. Use the hosted service or self-host the same image, and drive it via HTTP or a native MCP server with a stdio binary. Pricing is flat-rate per organization with a generous free tier.
