WriteFreely

Latest release - - Go Report Card - Build status + + Go Report Card +

  -WriteFreely is a beautifully pared-down blogging platform that's simple on the surface, yet powerful underneath. +WriteFreely is free and open source software for building **a writing space** on the web — whether a publication, internal blog, or writing community in the fediverse. -It's designed to be flexible and share your writing widely, so it's built around plain text and can publish to the _fediverse_ via ActivityPub. It's easy to install and light enough to run on a Raspberry Pi. +![](https://writefreely.org/img/screens/pencil-reader.png) -[Try the editor](https://write.as/new) +[Try the writing experience](https://write.as/new) [Find an instance](https://writefreely.org/instances) ## Features -* Start a blog for yourself, or host a community of writers -* Form larger federated networks, and interact over modern protocols like ActivityPub -* Write on a fast, dead-simple, and distraction-free editor -* [Format text](https://howto.write.as/getting-started) with Markdown -* [Organize posts](https://howto.write.as/organization) with hashtags -* Create [static pages](https://howto.write.as/creating-a-static-page) -* Publish drafts and let others proofread them by sharing a private link -* Create multiple lightweight blogs under a single account -* Export all data in plain text files -* Read a stream of other posts in your writing community -* Build more advanced apps and extensions with the [well-documented API](https://developers.write.as/docs/api/) -* Designed around user privacy and consent +### Made for writing -## Hosting +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. -We offer two kinds of hosting services that make WriteFreely deployment painless: [Write.as Pro](https://write.as/pro) for individuals, and [Write.as for Teams](https://write.as/for/teams) for businesses. Besides saving you time and effort, both services directly fund WriteFreely development and ensure the long-term sustainability of our open source work. +### A connected community -### [![Write.as Pro](https://writefreely.org/img/writeas-pro-readme.png)](https://write.as/pro) +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. -Start a personal blog on [Write.as](https://write.as), our flagship instance. Built to eliminate setup friction and preserve your privacy, Write.as helps you start a blog in seconds. It supports custom domains (with SSL) and multiple blogs / pen names per account. [Read more here](https://write.as/pro). +### Intuitive organization -### [![Write.as for Teams](https://writefreely.org/img/writeas-for-teams-readme.png)](https://write.as/for/teams) +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. -[Write.as for Teams](https://write.as/for/teams) gives your organization, business, or [open source project](https://write.as/for/open-source) a clutter-free space to share updates or proposals and build your collective knowledge. We take care of hosting, upgrades, backups, and maintenance so your team can focus on writing. +### International -## Quick start +Blog elements are localized in 20+ languages, and WriteFreely includes first-class support for non-Latin and right-to-left (RTL) script languages. -WriteFreely has minimal requirements to get up and running — you only need to be able to run an executable. +### Private by default -> **Note** this is currently alpha software. We're quickly moving out of this v0.x stage, but while we're in it, there are no guarantees that this is ready for production use. +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. -To get started, head over to our [Getting Started guide](https://writefreely.org/start). For production use, jump to the [Running in Production](https://writefreely.org/start#production) section. +
