http://webscanner.tk/quickscan/ Hi! I made this project over the couse of a week to help teach myself more about Django and web app development. I am studying computer security in school and web security is one of my passions. It is a tool that helps web developers ensure that they have implemented helpful security mechanisms like HTTPOnly flags, X-Frame-Options, etc. There are hundreds of tools that offer to scan websites for things like cross-site scripting, mySQL injection, etc. This tool simply looks for information that is available via one or two GET requests (the headers, protocols,…

I built this after seeing multiple teams accidentally ship API keys in their frontend code. The problem: Modern web development moves fast. You're vibe-coding, shipping features, and suddenly your AWS keys are sitting in a tag visible to anyone who opens DevTools. I've personally witnessed this happen to at least 3-4 production apps in the past year alone. KeyLeak Detector runs through your site (headless browser + network interception) and checks for 50+ types of leaked secrets: AWS/Google keys, Stripe tokens, database connection strings, LLM API keys (OpenAI, Claude, etc.), JWT…

Hi HN, I'm an Indie Dev. Building web apps, I struggled to check for vulnerabilities on a surface and a deeper level at the same time. Most free scanners gave vague results or missed dependency issues and tools for deeper searches are mainly for enterprise. Also with vibe coding the issue of security is rising more and more. I built SecureNow - a simple web scanner built with Next.js and Supabase that checks SSL, ports, dependencies, headers, and basic vulns. It caught real issues in my projects. Free basic scans at securenow.app. Feedback on accuracy and missing features? Thanks!

AttackerView▲13Last week I wrote about building a scanner that writes its own exploits. A cron job runs Claude Code every night, it reads new CVEs, writes proof-of-concept checks, tests them against vulnerable and patched Docker instances, and opens PRs. I review and merge in the morning. That post was about how t
