WriteFreely


Latest release - - Go Report Card - Build container image, publish as GitHub-package

  WriteFreely is a clean, minimalist publishing platform made for writers. Start a blog, share knowledge within your organization, or build a community around the shared act of writing. ![Screenshot of the Reader view of a WriteFreely instance, pen.writefree.ly.](https://files.writefreely.org/img/screens/pen-reader.png) [Try the writing experience](https://write.as/new) [Find an instance](https://writefreely.org/instances) ## Features ### Made for writing Built on a plain, auto-saving editor, WriteFreely gives you a distraction-free writing environment. Once published, your words are front and center, and easy to read. ### A connected community Start writing together, publicly or privately. Connect with other communities, whether running WriteFreely, [Plume](https://joinplu.me/), or other ActivityPub-powered software. And bring members on board from your existing platforms, thanks to our OAuth 2.0 support. ### Intuitive organization Categorize articles [with hashtags](https://writefreely.org/docs/latest/writer/hashtags), and create static pages from normal posts by [_pinning_ them](https://writefreely.org/docs/latest/writer/static) to your blog. Create draft posts and publish to multiple blogs from one account. ### International Blog elements are localized in 20+ languages, and WriteFreely includes first-class support for non-Latin and right-to-left (RTL) script languages. ### Private by default WriteFreely collects minimal data, and never publicizes more than a writer consents to. Writers can seamlessly create multiple blogs from a single account for different pen names or purposes without publicly revealing their association.

Write.as

The quickest way to deploy WriteFreely is with [Write.as](https://write.as/writefreely), a hosted service from the team behind WriteFreely. You'll get fully-managed installation, backup, upgrades, and maintenance — and directly fund our free software work ❤️ [**Learn more on Write.as**](https://write.as/writefreely). ## Quick start WriteFreely deploys as a static binary on any platform and architecture that Go supports.
