WriteFreely is open source software for running a blog or publishing platform in which writing comes first. It has a fast, auto-saving editor and a calm reading experience, with no news feed, notifications or likes. Through ActivityPub, people on Mastodon and other compatible services can follow a blog, bookmark posts and share them. It can also host a community of several writers. WriteFreely is written in Go and runs as a single binary, using SQLite, MySQL or MariaDB for storage; Docker is supported. Self-hosting is therefore straightforward. A managed option is available through Write.as.
The software is licensed under the AGPL-3.0 and maintained by Musing Studio LLC, the team that also runs Write.as, which describes itself as "Made in NYC". The documentation does not say where Write.as hosts its data. For a European organisation that wants control over its data, self-hosting on its own or European infrastructure is the clearest route: the source code is fully open to inspection and no vendor is needed to operate the platform.
