Feather is a hosted blogging platform that uses Notion as its CMS (content management system, the place where posts are written and stored). Feather is an independent product that works through Notion's API; it is not owned by Notion or partnered with it.
Setup has four steps: connect Notion databases (the customer's own or a duplicated template), map the Notion fields to Feather fields, choose a domain, and publish. The blog can live on a subdomain such as blog.example.com, on the main domain, or in a subfolder of an existing site such as example.com/blog, which the site recommends for SEO (search engine optimization). Feather sets meta tags, canonical links and schema markup, serves pages from the edge for speed, and adds an automatic sitemap, RSS feed, search, tags, related posts, multiple authors, email collection and built-in analytics of page views, visitors and referrers. A free Notion plan is enough.
It is a subscription service priced by monthly page views, with unlimited blog sites and a 7-day free trial.
