Sitemapper

Website change intelligence for production safety

Sitemapper launched on August 25, 2026 with 2 votes, #5,788 of 23,274 launches that month.

What it does

Sitemapper watches production websites and compares each trusted crawl with the last. It surfaces changes to sitemap inventory, indexability, HTTP status, canonicals, robots access, and critical journeys—then explains why a change matters and what to check next. A free public survey works without signup; monitoring, incident history, alerts, CI guardrails, API access, and Search Console support are available in the app. Built around preserved evidence, not invented impact.

Website change detection and safety. Free public check, then monitor pages, search visibility, and critical journeys after deploys.

robots.txt, then XML sitemaps, then a live page sample. Typical scans finish in 8–40 seconds. Free check of any public site — no account. Monitoring compares sitemap inventory, live page signals, and critical journeys between crawls, then shows the likely risk and where to investigate. Any homepage. The checker is free. Keep the snapshot if you want a clear comparison after the next deploy. 1,493 public checks · 105,731 sitemap URLs found across checks · preview cap 1,200 sitemap URLs / 40 live page checks. You’ll see robots → sitemap inventory → live sample. Timing depends on origin and sitemap size; slow discovery is reported as inconclusive. A deploy can ship noindex, hide a sitemap, or…from sitemapper.oortstack.com

    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…

  • Hey 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…
