Publish content, send email newsletters, and sell paid subscriptions from one platform. Used by independent journalists, creators, and businesses like YCombinator and Kickstarter.

Ghost is a publishing platform built for professional creators who want to run a content business without depending on third-party algorithms or platforms. It combines a website builder, email newsletter delivery, and membership management into one tool. Independent journalists, newsletters, and media companies use it to own their audience directly.
The editor is designed to stay out of the way. It supports rich media through embeds and content blocks: image galleries, video, audio, downloadable files, bookmarks, accordion toggles, and more. Posts can be published to the web and delivered by email simultaneously, with audience segmentation so you can send different newsletters to different subscriber groups.
Memberships are built in from the start:
For site design, Ghost supports custom themes and a marketplace with hundreds of options. Your branding stays front and center. It integrates with tools like Zapier, Slack, Discord, Google Analytics, Plausible, Mailchimp, ActiveCampaign, and many others.
Ghost is self-hostable or available as a managed service. It's structured as an independent nonprofit funded entirely by its users, with no outside investors. Publications on Ghost collectively generate over $100 million in revenue annually. If you're moving away from WordPress or looking for a Beehiiv alternative, Ghost covers both the website and newsletter sides without needing separate tools.

Self-hosted platform for publishing text anonymously. Write, get a link, share it. No accounts, no tracking, no edits after posting.

Nonograph is a bare-bones anonymous publishing platform for anyone who wants their words to exist online without being tied to an identity. You write, you get a shareable link, and that's it. No account creation, no profile, no analytics trail following readers around.
It's built around a few hard constraints that shape the whole experience:
Formatting works through Markdown directly, or via a / menu for those who prefer a guided approach. Appending .md to any post URL reveals the raw source, which keeps things transparent and portable.
The permanence-by-design approach makes it a different choice from platforms like Posthaven, where posts can be managed and updated. Nonograph treats publishing as a one-way door. That constraint is the point: it removes the temptation to self-censor after the fact, and it means there's no moderation surface tied to your identity.
Because it's self-hostable and lightweight, running your own instance is straightforward. The codebase is intentionally simple, which keeps long-term maintenance low. No investors, no monetization, no ads mean the project has no financial pressure to change what it is.

Key benefits of Zenblog include:

Publish blog posts by email, from Obsidian, iA Writer, the web editor, CLI, or API. Includes RSS, email subscribers, analytics, custom domains, and full export.

Pagecord is a personal blogging platform built around one idea: removing friction between the urge to write and a published post. It doesn't force you into a new workflow. You can write in the browser, send an email to your private Pagecord address, publish from Obsidian or iA Writer, or push posts from the terminal using the CLI or API.
The free tier covers the basics well. Unlimited posts and pages, a choice of themes, tags, RSS, media embeds (YouTube, Spotify, Bandcamp, GitHub auto-embed), full site export in HTML or Markdown, and a built-in rich text editor. No time limits, no post caps.
Premium ($39/year or $4/month) adds the features that make a blog feel like a real home on the web:
Exporting your entire site (including images) in HTML or Markdown is available to everyone, not just paying users. There's no lock-in by design.
Pagecord is open source and self-hostable, bootstrapped and profitable, and built with semantic HTML, RSS, and Micropub rather than heavy JavaScript frameworks. It's a deliberate contrast to bloated publishing platforms and newsletter engines like Ghost or tools like Zenblog that take a narrower approach.
It's used by 1,000+ independent bloggers who want a permanent, personal corner of the web without the overhead of managing a CMS.
