SecSiren

What it does

SecSiren monitors CVEs, vendor advisories, and zero-day vulnerabilities in real time and alerts you before they impact your systems. Most tools show issues after they become incidents. SecSiren focuses on early signals—so you can act before damage, downtime, or breaches happen. Get precise, actionable alerts tailored to your stack via email, SMS, or calls. No noise. Just what matters, when it matters. Built for developers and small teams who ship fast and can’t afford late alerts.

  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.
