PostSider connects to blogging and publishing platforms, letting you write once and publish to multiple destinations. This section covers WordPress, Medium, Dev.to, Hashnode, Ghost, Notion, Mataroa, Write.as, Blogger, Google Business Profile, Listmonk, Lemmy, Moltbook, and Whop.
Most platforms in this section use direct credential entry. Blogger and Google Business Profile use Google OAuth, while Listmonk uses its instance URL, username, and password. OAuth platforms require server-side app credentials on self-hosted deployments.
