Cross-post from Medium to Dev.to (and back) with canonical URLs

Postwire is a cross-posting tool for long-form articles that prepares one canonical article on Medium and Dev.to, with the canonical link pointing back to your own site, ready for you to publish.

Canonical first

The safe way to cross-post is to publish on your own site first and point every copy at it with a canonical URL, so search engines credit the original. Postwire requires a canonical URL for Medium variants for exactly this reason.

Both are filled by the Chrome extension. On Dev.to it creates a draft in the editor with the canonical URL set; on Medium it uses the 'Import a story' flow, which pulls the article from the canonical URL. You click publish on each.

What your agent sends

The long markdown in the package is the article. Postwire uses it for Dev.to directly, while Medium imports from the canonical page. Images come from the package and are served from the hub.

Medium is capped at one post a day by default.

Frequently asked

Will cross-posting hurt my SEO?
Not when every copy declares the original as canonical, which Postwire does for Medium and Dev.to.
Does Medium have an API?
Medium's publishing API is not open to new integrations, so Postwire uses the browser extension and Medium's own import flow instead.
Can I cross-post to Hashnode too?
Hashnode is not supported yet.
