Checkstack

What it does

Self-hosted, source-available status page and uptime monitoring with 13+ health checks, SLOs, incident management, GitOps and multi-channel alerts.

Self-hosted, source-available monitoring with an AI agent & MCP server, dependency-aware SLOs, 15+ health checks, metric & log streams, automations and GitOps.

Checkstack is the self-hosted monitoring platform for SRE and DevOps teams: health checks, metric streams, log streams, dependency-aware SLOs, and an AI agent that proposes and applies fixes. One Docker image, one license, 0€ forever - self-hosted like it's a feature, not a compromise. Every signal feeds the same health pipeline, the same assertions, the same alerts. What proprietary suites sell as costly add-ons ships in one self-hosted deployment. Actively probe every layer of your stack with 15+ strategies and flexible assertions. Push metrics over OTLP or JSON, or scrape your Prometheus exporters - then alert on rates, averages, and staleness. Ship logs via OTLP, syslog, or JSON -…from checkstack.dev

  Statusduck – Website monitoring tool where the data is public2024 · statusduck.io · ▲78

  Hello HN! We're excited to share Statusduck, an uptime monitoring tool where the data is publicly viewable. There are an uncountable amount of uptime tools but we thought we'd put a fun spin on the concept by making another one where people can immediately set up a monitor without signing up. Just type in a website and our service will start pinging it every minute!

  I built a self-hosted status page and monitoring tool for my projects2024 · github.com · ▲103

  Hey HN! I'm excited to share Statusnook - a status page and monitoring tool. I built Statusnook for my own projects, but I soon began incorporating bits of feedback from friends & colleagues. My goal was to create a tool with a solid essential feature set, and to make it easy to self-host. I welcome any feedback or suggestions.

  Talanoa▲346

  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…

  Needle: We Distilled Gemini Tool Calling into a 26M Model▲776

  Hey HN, Henry here from Cactus. We open-sourced Needle, a 26M parameter function-calling (tool use) model. It runs at 6000 tok/s prefill and 1200 tok/s decode on consumer devices. We were always frustrated by the little effort made towards building agentic models that run on budget phones, so we conducted investigations that led to an observation: agentic experiences are built upon tool calling, and massive models are overkill for it. Tool calling is fundamentally retrieval-and-assembly (match query to tool name, extract argument values, emit JSON), not reasoning. Cross-attention…
