PostSider

PostSider is a social media publishing, scheduling, and automation platform for creators, founders, teams, developers, and AI agents.

It lets you manage and publish content across 30+ social networks and content platforms from a single dashboard. Instead of switching between multiple tools, you can plan posts in a shared calendar, create and preview content, schedule publications, manage multiple accounts, review analytics, and collaborate with your team from one place.

PostSider supports major platforms such as Instagram, Facebook, X, LinkedIn, TikTok, YouTube, Pinterest, Bluesky, Mastodon, Discord, Telegram, WordPress, Medium, Dev.to, Ghost, Google Business, and many others.

Main features

• Schedule and publish posts across 30+ platforms • Weekly and monthly content calendar • Multi-platform post composer and previews • Cross-platform analytics • Team collaboration and role-based access • Approval workflows • Bulk publishing with CSV import • Media management • Automated publishing queues • AI-assisted content rewriting and optimization • First-comment and post automation features • REST API for custom integrations • TypeScript/Node SDK • MCP support for AI agents • Webhooks and automation tools • Multiple social accounts and workspaces

AI agents and developer integrations

PostSider can also be used as a social media infrastructure layer for AI agents and applications.

Developers can connect their own tools through the REST API or SDK, while AI assistants and agents can interact with PostSider through MCP.

This allows tools such as Claude, Codex, Cursor, or custom agents to work with social publishing workflows without requiring separate integrations with every social network.

Agents can be used to prepare content, create drafts, schedule posts, manage publishing workflows, and access supported social media functionality through a single integration.

Built for both humans and automation

PostSider is designed to work both as a traditional social media management application and as a programmable publishing platform.

Creators and teams can use the visual dashboard, calendar, composer, analytics, and collaboration features, while developers and AI systems can use the same platform programmatically through the API, SDK, and MCP.

This makes PostSider suitable for:

• Content creators • Solo founders • Startups • Marketing teams • Social media managers • Agencies • Developers • SaaS products • Automation workflows • AI agents

PostSider was originally created as an internal tool for managing social media across multiple projects and later developed into a standalone platform.

The goal is to provide one consistent layer for creating, scheduling, publishing, and managing content across many different platforms without having to maintain separate integrations or workflows for each network.
