Sitewatch
I built Sitewatch because I often want a fast way to sanity-check a site without installing tools, setting up monitoring, or creating an account. Sitewatch runs instant checks for SSL configuration, DNS resolution, HTTP status, and common security headers. Everything is usable without logging in or providing an email. The focus is on keeping the checks quick and frictionless. Monitoring and alerts are planned next, but I wanted to share the core tools early to get feedback on what’s useful and what’s missing. I built this myself and I’ll be around to answer questions or discuss…

Fast checks for SSL certificates, DNS configuration, HTTP status, and common security headers — designed to be quick, simple, and usable without signups or dashboards.
Developer toolkit for HTTP, DNS, SSL, DMARC, and WHOIS checks. Browser-based, no install, no signup.

I made tool that let's you see everything about any website2024 · v1.web-check.xyz · ▲411Yes, it's open source: https://github.com/lissy93/web-check :) Why I'm building this? There are a lot of tools out there for discovering meta and security data relating to a website, IP or server. But currently, there isn't anything that does everything, all in one place and without a paywall/ user sign up. It's still a WIP, and I'm working on a new version, with some more comprehensive checks, so any feedback would be much appreciated :)
I built a tool that watches webpages and exposes changes as RSSMar 2026 · sitespy.app · ▲320I built Site Spy after missing a visa appointment slot because a government page changed and I didn’t notice for two weeks. It watches webpages for changes and shows the result like a diff. The part I think HN might find interesting is that it can monitor a specific element on a page, not just the whole page, and it can expose changes as RSS feeds. So instead of tracking an entire noisy page, you can watch just a price, a stock status, a headline, or a specific content block. When it changes, you can inspect the diff, browse the snapshot history, or follow the updates in an RSS reader. It’s…
exit1.dev2025 · exit1.dev · ▲11I'm trying to disrupt the insane pricing of uptime monitoring. I hope you'll help me out. I'm trying to create the absolute cheapest dev monitoring tool on the market, while still being competitive with all the others. This means $3/month plan, while still having monitoring for: Website, REST API, UDP/TCP, ICMP, Heartbeat/CRON, WS/WSS, DNS, Domain Intel/expiry and SSL. Everything with unlimited alerts through webhooks. I'm also taking an unlimited approach to the amount of checks you can have. I'd love to hear your thoughts.

Talanoa▲346Hi 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…

Hey HN! I wanted to share something I built over the last few weeks: isometric.nyc is a massive isometric pixel art map of NYC, built with nano banana and coding agents. I didn't write a single line of code. Of course no-code doesn't mean no-engineering. This project took a lot more manual labor than I'd hoped! I wrote a deep dive on the workflow and some thoughts about the future of AI coding and creativity: http://cannoneyed.com/projects/isometric-nyc
