Get started

1

Install or self-host PostSider

Run PostSider with Docker Compose in minutes. See the Self-Hosting guide for full instructions.
2

Connect a channel

Add your first platform from Channels. Cloud has provider apps configured. Self-hosted instances must add the relevant OAuth Client ID and Secret to .env; token-based providers can be configured in the dashboard.
3

Schedule your first post

Use the visual calendar, the API, the SDK, or the MCP server to schedule your first post. See the Quickstart to try all three approaches.
4

Automate with agents

Connect Claude Code, Codex, or any MCP-compatible agent to PostSider’s MCP server. The server is a developer tool you build from the repository source.
PostSider is available as PostSider Cloud (https://app.postsider.com) or self-hosted on your own infrastructure. See Quickstart to start, or Self-Hosting to deploy your own instance.
