What it does
Free passive website scanner: security headers, CSP, TLS, DNS, exposed paths and CVE mapping, plus an AI-authorship likelihood score for any site.
Free website security scanner online: check website security, find vulnerabilities, check SSL & headers, find subdomains and exposed files, and detect if a website is AI generated — all in one passive scan.
Vulnexa runs a deterministic, passive audit DNS, TLS, redirects, headers, CSP, privacy notice, exposures and CVE mapping then reports a security score and an AI-authorship likelihood index side by side. Educational security research only scan only what you are permitted to test. Same input, same evidence, same output every run is fingerprinted. Resolve the host, follow redirects, canonicalize the target. Weighted, auditable sub-scores across domain trust, TLS, redirects, headers, CSP, reputation, exposures, privacy notice, frontend hygiene and attack surface. Higher is safer. Builder fingerprints, generic copy patterns, framework defaults, bundle traces and structural repetition weighed…from vulnexa.com

Clipto MCP▲655Hey HN, We recently built Clipto. It’s a tool that lets you search over terabytes of video, audio, and images on your computer, without relying on the cloud. Motivation: we probably all had this similar experience, we know a moment exists in a video or audio, but finding it takes hours scrubbing the timeline. You can send all the media to process in the cloud, but it’s slow, expensive and raises privacy concerns. So we decided to build our own on-device media search engine. How it works (high level): 1. We ingest video, audio, image; normalize formats via ffmpeg; run content analysis to…

Hello HN! I found that picking out plausible but diverse skin tones for my digital art and game development projects was kind of difficult, and I got curious about if there was a way to define a color space that made it easy. I've built a color picker and procedural generation algorithm based on the space as well as a bunch of other fun js features and demos throughout the page that use the equations. If you find it interesting, I have lots of explanations of how I built it and what properties the space has. The methodology might be a bit shaky, but hopefully the result is as helpful for…
