Buttondown is a minimal newsletter tool for writers and developers, offering clean subscriber management, Markdown editing, and a straightforward API without bloat.
Buttondown is an independent newsletter platform founded and operated by Justin Duke, designed as a minimal, well-crafted alternative to the feature complexity and opinionated workflows of larger newsletter and email marketing platforms for writers, developers, podcasters, and independent researchers who want a tool that stays out of their way and lets them focus on writing. Buttondown prioritizes correctness, transparency, and craftsmanship over feature accumulation — a positioning that has built a loyal following among technically discerning writers who value a codebase maintained by a single developer with clear values over the feature churn and pricing volatility associated with venture-backed platforms.
London open-source headless CMS for subscription media; built-in newsletter delivery, Stripe-powered memberships, and modern editing tools for independent publishers and journalists.
Ghost is a London-based independent technology company that develops and maintains Ghost, an open-source headless content management system purpose-built for independent publishers, journalists, and newsletter creators. Unlike WordPress, which was built for website publishing, Ghost is optimized for subscription-based media businesses — it includes built-in newsletter delivery, paid membership subscription management via Stripe, and modern content creation tools in a fast, SEO-optimized platform. Ghost is available as open-source self-hosted software (free) and as a managed cloud service (Ghost Pro, paid), with the managed revenue funding continued open-source development. The platform has been adopted by independent media companies, Substack migrants seeking more control, and enterprise teams at companies including Mozilla and Square. Founded as a Kickstarter project in 2013 by former WordPress head of UX John O'Nolan, Ghost is structured as an independent non-profit foundation. Ghost Pro serves tens of thousands of publications and has processed hundreds of millions in creator revenue. It competes with Substack, Beehiiv, and ConvertKit in the newsletter and creator publishing market.
