Seiri

What it does

Cron job & heartbeat monitoring for scheduled jobs and Kubernetes CronJobs. Get alerted when a job stops checking in — not website uptime. Free Tier is free forever. Unlike uptime monitors that only check if your site is up, Seiri watches whether your actual jobs ran — cron, Kubernetes CronJobs, and webhooks alike. Set up in minutes, alerts via Slack, Discord, Telegram, Email, or SMS.

Seiri is push/heartbeat monitoring for cron jobs, workers, and Kubernetes CronJobs — not website uptime monitoring, and not a cron-webhook scheduler. Your job checks in when it finishes; if that check-in is late, you're alerted before customers or finance find out. alert sent → #ops-alerts, [email protected] 02:15:04 UTC # before — runs silently, fails silently 0 2 * * * /path/to/backup-script.sh # after — the ping only fires on success 0 2 * * * /path/to/backup-script.sh && \ curl -fsS https://ping.seiri.app/webhook/acme-demo:NkdyngWn9z/success See it before you sign up for anything Same dashboard real customers use, seeded with monitors, a missed check-in, and a public status page.…from seiri.app

  Talanoa▲341

  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…

  Clipto MCP▲655

  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…

  Simple algorithm and color space to generate diverse skin tones▲627

  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…
