CogSend

CogSend is a self-hosted social media scheduler that runs on your own Cloudflare account, keeping your data and credentials under your control. Write a post once, customize it per platform, then publish immediately or schedule for later across Mastodon, Bluesky, LinkedIn, Threads, and X. It includes a thread editor, automatic retry logic, and per-platform delivery insights.

Designed for individuals and small teams managing multiple social networks, CogSend offers features like auto-splitting long posts into platform-appropriate threads, per-destination overrides, and failure tracking grouped by reason. The project supports AI agents via MCP protocol and includes an API for scripting. It runs on Cloudflare's free plan with no subscription required.
