PostOwl
What PostOwl is
PostOwl is an open-source web application for running a personal blog, private journal, or letter-sharing site. It supports self-hosting, custom domains, and browser access on any device with a web browser. Editing takes place directly on the site instead of through a separate administration panel. Users can send letters through secret links and notify recipients by email. The home page lists RSS feeds, search, and email notifications as features. PostOwl stores all content, including images, in one SQLite database file that can be copied for backup. The deployment guide currently focuses on Fly.io, while the maker describes deployment as a technical preview requiring technical knowledge. A hosted version is described as coming soon. Email notifications use Nodemailer, with Mailgun recommended when an SMTP server is needed. The self-hosted plan costs nothing and requires you to host the application. Backups are currently manual.
