PostSider is a social media publishing platform built for humans and AI agents. Schedule and publish content across 30+ platforms from one place, or connect Claude, Codex, Cursor, or your own agent through MCP, REST API, or SDK. Manage your content calendar, analytics, teams, approvals, and automation without juggling multiple tools.

Hey Product Hunt 👋 I’m Łukasz, the founder of PostSider. I originally built PostSider for myself because managing content across multiple social platforms was becoming too fragmented and time-consuming. What started as an internal tool slowly turned into a full social media publishing platform for creators, founders, teams, and now also AI agents. With PostSider, you can schedule and publish content across 30+ platforms from one place, manage your content calendar, analytics, approvals, and teams, or connect Claude, Codex, Cursor, or your own AI agent through MCP, REST API, or SDK. One of the things I’m most excited about is the agent side of PostSider. I believe social media tools will increasingly be used not only by humans, but also by AI agents that can prepare, schedule, analyze, and manage content workflows. PostSider is my attempt to build the infrastructure for both. I’d really appreciate your feedback, especially on what integrations, automations, or features you’d like to see next. Thanks for checking it out ❤️

A preview showing how the same post will look on each platform would be really helpful before scheduling it.

The content calendar plus approvals sounds really handy for teams. It could cut down a lot of back and forth.

I could see myself using this for weekly content planning. Having the posts, approvals and schedule together would make things less messy.
