1. Netdata

   1 131 79,691 10.0 Go

   The open-source observability platform everyone needs

   

   Project mention: Best Open Source Monitoring Tools in 2026: 7 Self-Hosted Options Compared | dev.to | 2026-06-13

   Netdata is a real-time infrastructure monitoring agent that collects metrics at per-second granularity with near-zero configuration. Install the agent on a server, and within seconds you have 2,000+ metrics being collected — CPU, memory, disk I/O, network, processes, containers, and hundreds of application-specific collectors. The level of instant visibility is unmatched.

3. prometheus

   2 515 65,219 9.9 Go

   The Prometheus monitoring system and time series database.

   

   Project mention: How To Learn Go Fast: A Practical Roadmap For Senior Backend Developers | dev.to | 2026-06-26

   prometheus/prometheus — production observability,

4. sampler

   3 11 14,570 0.0 Go

   Tool for shell commands execution, visualization and alerting. Configured with a simple YAML file.

   

5. nightingale

   4 4 13,142 9.6 Go

   Nightingale is to monitoring and alerting what Grafana is to visualization.

   

6. gatus

   5 46 11,544 9.0 Go

   Automated developer-oriented status page with alerting and incident support

   

   Project mention: Best Open Source Monitoring Tools in 2026: 7 Self-Hosted Options Compared | dev.to | 2026-06-13

   Gatus is a developer-friendly health monitoring tool written in Go. You define endpoints and health conditions in a YAML file, Gatus checks them on a schedule, and it serves a clean status dashboard. No database required — it stores data in memory (with optional persistence to SQL). It's what you'd build if you wanted a monitoring tool that fits in a single config file.

7. coroot

   6 55 7,830 9.2 Go

   Coroot is an open-source observability and APM tool with AI-powered Root Cause Analysis. It combines metrics, logs, traces, continuous profiling, and SLO-based alerting with predefined dashboards and inspections.

   

   Project mention: Zero-config Golang Heap Profiling | dev.to | 2026-04-30

   Coroot is an Apache 2.0 open source platform that simplifies observability with no-code configuration. The Coroot node-agent already collects CPU profiles for any process on the node using eBPF, with zero integration from the application side. For Java, we dynamically inject async-profiler into the JVM to get memory and lock profiles. But Go processes were still a blind spot for non-CPU profiling unless the app exposed a pprof endpoint and the cluster-agent scraped it.

8. sloth

   7 11 2,513 8.7 Go

   🦥 Easy and simple Prometheus SLO (service level objectives) generator (by slok)

   

9. easeprobe

    The only tool you need to know what is happening and how to fix it.

    

    Project mention: Traceway: MIT-licensed observability stack you can self-host in ~90s | news.ycombinator.com | 2026-05-11

13. slo-exporter

    12 1 193 0.0 Go

    Slo-exporter computes standardized SLI and SLO metrics based on events coming from various data sources.

    

14. maintenant

    13 2 188 - Go

    Drop a container. Your stack is monitored.

    

    Project mention: I shipped a 20-feature DevOps tool solo in 60 days using Claude Code — the unfiltered breakdown | dev.to | 2026-05-07

    TL;DR — I built Maintenant, a 20-feature monitoring tool (Docker + Kubernetes + endpoints + certs + alerts + status page + MCP server), solo, in two months, with Claude Code. AGPL-3.0 open-core, Pro tier at €29/month, real users in production. This post is not a pitch. It's the honest breakdown — what actually got 10x'd, what completely wasted my time, what I'd never claim about AI coding, and why the code was probably the easiest part. If you're a senior dev considering whether to bet on LLM-augmented development, this is what the inside actually looks like.

15. SyMon

    14 1 185 0.0 Go

    A simple system monitoring and alerting tool to monitor server HW stats. (by dhamith93)

    

16. rezible

    Open-source oncall management Alerts, Incidents, AI post-mortems. Self-hosted alternative to PagerDuty & incident.io. BYO-AI, Works with Prometheus, Grafana, Datadog, Slack, and Teams (by FluidifyAI)

    

    Project mention: Found Better Pagerduty Alternative | news.ycombinator.com | 2026-07-12
