What it does

Create production-ready SaaS backends instantly with full multi-tenant isolation. Each tenant gets its own database, API, and subdomain. Generate CRUD endpoints, authentication, and token protection out of the box. Modify routes dynamically at runtime without redeploy. Test APIs from a built-in lab and export requests as code. Powered by Docker and Caddy for auto HTTPS and scalable deployment. No setup, no boilerplate.

  I built a frontpage for personal blogs▲783

  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.
