Build freely. Sleep peacefully. Let the Owl Watch
What it does
RestingOwl is a platform (under development and released soon) that provides secure-by-default open-source packages designed to align with OWASP best practices (extended to other standards later) and prevent common security mistakes. owlauth, its first package, is an npm package for authentication. It supports signup, login, password management, passwordless magic links, rejecting weak passwords, breach detection, safe audit logging, and many more (refer to the NPM organization). More to come.

With social media and now AI, its important to keep the indie web alive. There are many people who write frequently. Blogosphere tries to highlight them by fetching the recent posts from personal blogs across many categories. There are two versions: Minimal (HN-inspired, fast, static): https://text.blogosphere.app/ Non-minimal: https://blogosphere.app/ If you don't find your blog (or your favorite ones), please add them. I will review and approve it.
