  Osint tool that finds exposed files on domainsJul 2026 · search.cerast-intelligence.com · ▲58

  hey guys, wanted to show one of my side projects i just made public. the idea is basically another osint tool for pentesters and bug bounty hunters. it watches certificate transparency logs and checks newly-seen domains for exposed stuff like .env files, open .git dirs, config files, db dumps and so on, and puts whatever it finds into a searchable db. you just search a domain (or part of one) and see what's exposed. it's read-only and free. one thing i've been thinking about adding is a way to register for certain keywords and get notified when something new shows up for that search. would…

  I built an OSINT tools directory2025 · r00m101.com · ▲53

  I work on R00M 101, a Reddit-based OSINT profiler. While building it, I realized most open-source intelligence (OSINT) tools are scattered across GitHub, outdated blog posts, or random Discords. So I put together a public-facing directory of 100+ OSINT tools used by analysts, journalists, and security folks, free, filterable, and categorized by risk, platform, and use case. The idea was to make something useful and no-friction. Built with static HTML + SQL backend + a lot of caffeine. Would love feedback on how to improve the UX or tool curation. If anyone wants to contribute tools or help…

  Talanoa▲346

  Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…

  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.
