What it does
CertChecker watches every domain you manage and emails you before an SSL certificate or domain registration expires -- so you find out first, not your client.
CertChecker watches every domain you manage and emails you well before an SSL certificate or domain registration lapses -- so you find out from us, not from an angry client. Paste in one domain or bulk-import a whole list. A check runs immediately, so you see real data right away. SSL certificate, domain registration, and uptime -- checked daily on the free plan, as often as every 6 hours on Pro. Alerts fire at 30, 14, 7, and 1 days before expiry -- a real window to renew, not a surprise after the site is already down. Know the moment a client's certificate is about to expire, not after their site starts throwing browser warnings. Catch a lapsed domain registration before it lapses -- and…from certchecker.dev

Clipto MCP▲655Hey 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…
