What it does
After 4 years from the first launch of the project, here we are back with a milestone upgrade in terms of the project's startegic direction, as well as in terms of content and user experience. OSINTGuide is a curated directory of open-source intelligence (OSINT) tools and practical guides.

I built an OSINT tools directory2025 · r00m101.com · ▲53I 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 While building it, I realized most open-source intelligence (OSINT) tools are scattered across GitHub, outdated blog posts, or random Discords.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…

Our weekend project - HN Showcase, browse "Show HN" posts2011 · hnshowcase.com · ▲63http://www.hnshowcase.com Moses (nnythm) and I browse Hacker News daily. Show HN posts are some of our favorite parts of HN. We wanted to create a way to browse Show HN articles, even those that might not quite make it to the front page. We created http://www.hnshowcase.com last weekend to make discovering projects posted on HN easier. It searches all "Show HN" posts and generates a thumbnail view for each of them. You can sort by submission date, points, and number of comments, and navigate with left/right or j/k keys. We used the following technologies: HN Search API, Pyramid web…
I built a knife steel comparison tool2025 · new.knife.day · ▲146Hey HN! I'm a bit of a knife steel geek and got tired of juggling tabs to compare stats. So, I built this tool: https://new.knife.day/blog/knife-steel-comparisons/all It lets you pick steels (like the ones in the screenshot) and see a radar chart comparing their edge retention, toughness, corrosion resistance, and ease of sharpening on a simple 1-10 scale. It's already been super handy for me, and I thought fellow knife/metallurgy enthusiasts here might find it useful too. Would love to hear your thoughts or any steel requests! Cheers!

Hey HN! Tired of hitting "Sign up for free" buttons only to discover the real limitations after creating an account? Or finding a "free" tool that adds watermarks to everything? Yeah, me too. I'm building kis.tools, a curated directory of tools that: Work instantly - registration only when technically necessary, have genuine free functionality, keep interfaces clean and focused, process data locally when possible, keep promotional messages or ads minimal and unobtrusive Think of it as a home for tools like Eric Meyer's Color Blender (running since 2003!) - tools that do one thing, do it…
Osint tool that finds exposed files on domainsJul 2026 · search.cerast-intelligence.com · ▲58hey 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…
