Most security feeds bury you in CVEs that have nothing to do with what you ship. 0Day cuts through that. Zero-days, supply chain attacks, compromised packages, active exploits: filtered to your exact stack, the moment they break. Pick your stack once during onboarding: npm, PyPI, Docker, Kubernetes, React, Rails, OpenSSL, whatever you use and the feed shows you only what touches your tech. No noise. No irrelevant advisories. Just what matters to you. The goal is lead time. Know about a compromised package, a poisoned build pipeline, or an actively exploited CVE before it reaches your CI, your production deployment, or your customers. Before the news cycle. Before the stragglers patch. Before you're the one scrambling at 2am. WHY 0DAY - Privacy-first — no analytics, no tracking, no third-party SDKs - Early warnings before the news cycle — the moment a threat breaks, you know - Stack-aware filtering — see only threats that hit the tools you use - Multi-source corroboration — duplicates merged, sources ranked by tier - Curated, not firehose — every alert is tied to a specific component - Full archive — searchable history of every threat that hit your stack HOW IT WORKS Every item in the feed goes through a three-stage lifecycle so you can tell the difference between "we're watching this" and "this is real, act now": CANDIDATE — A single source has reported an incident. In the pipeline, being correlated, not yet corroborated. EARLY WARNING — Either an authoritative research outlet flagged it, or a second independent source has confirmed the same incident. Pushed to your device immediately — this is the lead time the product is built for. CONFIRMED — Two or more authoritative sources agree, or three independent sources total. High-confidence state you can act on without double-checking. INSIDE THE FEED Each alert gives you a plain-English summary, affected components with version ranges, recommended action, CVE and GHSA identifiers with tappable links to the upstream advisories, and a timeline of when each source reported the incident. PRIVACY We collect only what we need to run the service: your email for sign-in, your stack selections, your notification preferences, and your device token for push delivery. No analytics. No crash reporting SDKs. No advertising identifiers. No cross-app tracking. All data is stored in the European Union on AWS infrastructure. You can delete your account and all associated data instantly from Settings. SUBSCRIPTION 0Day Pro unlocks the full experience: early warning alerts, push notifications, full archive access, remediation guidance, and stack filtering.
