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 ❤️

I use Cursor a lot so wanted to ask if an agent schedules a post can we review and approve it before publishing? Also can we preview the post across all 30+ platform before it goes live?
Congrats on launch @luka83184 , Hope the launch goes well.
@tahir21 Thanks Muhammad! Yes, an agent can create a draft and send it for approval instead of publishing immediately. An admin or owner can then review the copy, media, channels, and scheduled time, and approve or reject it with a note. While approval is pending, the post cannot enter the publishing queue.
You can also switch between live previews for the selected platforms and tailor the content for each channel before approving it.
@busmark_w_nika Yes. You can remove an already published post from the PostSider dashboard. This removes it from your PostSider workspace, but it does not delete the live post from the social platform itself. That still needs to be removed directly on the platform.
@petomalina I’m taking it in a more focused direction around external AI agents and human oversight. Agents can work through MCP, REST API, or the SDK, while humans use the same calendar, previews, and approval workflow. PostSider also avoids becoming an AI content generator itself. The idea is that you can bring Claude, Codex, Cursor, or your own agent, then use PostSider as the controlled publishing layer.
In simply Terms Postsider is more like tool for ai agents, or automations.

A preview showing how the same post will look on each platform would be really helpful before scheduling it.
@desire_waterman Absolutely. This is already built into the composer. You can switch between previews for each selected platform and customize the caption per channel before scheduling.
Your comment tells me I need to make that feature much easier to notice during onboarding, though. Thank you!

Supporting both humans and again in the same publishing workflow is an interesting direction. Most social tools still seem designed around manual posting.
@luke_bell Exactly. I don’t want agents to become a separate publishing system that teams have to monitor. The goal is for humans and agents to share the same calendar, drafts, approval flow, and publishing history, with a human still able to step in whenever needed.

The content calendar plus approvals sounds really handy for teams. It could cut down a lot of back and forth.
@christian_onochie That was exactly my thinking, so I added approvals directly to the content calendar. It keeps drafts, feedback, and scheduling in one place instead of spreading the process across chats and documents. Thanks Christian!

Can we remove the post in the dashboard that was already published via this tool?
