Using Postbase
Connect channels, write posts and threads, schedule them on the calendar,
and reuse media across posts.
MCP & agents
Connect Postbase to Claude, Cursor, and other tools so an agent can schedule
and publish for you — with or without an API key.
Public API
A small REST API to list channels and create or cancel scheduled posts from
your own tools.
Self-hosting
Run your own Postbase on Next.js + Supabase. Bring your own platform apps
and storage.
How it’s organised
The docs are split by what you’re trying to do — use the product, wire up an
agent, call the API, or run your own instance.
- Using Postbase — the product: channels, composer, calendar, media, and analytics.
- AI — generate images and video right in the composer.
- Postbase Cloud — plans and billing for the hosted version.
- MCP & agents — overview, connecting a client, and the tools your agent can call.
- Public API — authentication, posts, and channels.
- Self-hosting — installation and configuration.
