Kener — Beautiful Open-Source Status Page Generator

Introduction

Kener is an open-source status page system built with SvelteKit. It provides automated uptime monitoring with HTTP, TCP, and DNS checks, combined with a manual incident management system and a modern, customizable UI for communicating service status to users.

What Kener Does

• Monitors services via HTTP, TCP, and DNS health checks at configurable intervals
• Displays real-time and historical uptime data on a clean, responsive status page
• Manages incidents with creation, updates, and resolution timelines
• Sends notifications through webhooks, email, and integration with services like Slack
• Generates embeddable status badges for READMEs and documentation

Architecture Overview

Kener is built on SvelteKit with server-side rendering for fast initial page loads. Monitoring runs as background jobs that execute health checks and store results in a local file-based data store. The status page is statically generated at configurable intervals for performance. Configuration is defined in YAML files covering monitors, incidents, and site settings.

Self-Hosting & Configuration

• Deploy with Docker for the simplest setup with volume-mounted configuration
• Define monitors in monitors.yaml with endpoint URLs, check intervals, and thresholds
• Customize the status page appearance with themes, logos, and custom CSS
• Configure notification channels for downtime alerts via webhooks or email
• Set up behind a reverse proxy with a custom domain for production use

Key Features

• Modern, responsive UI with dark mode and customizable branding
• YAML-based configuration for monitors and site settings (no database required)
• Incident management with status updates and resolution tracking
• Embeddable badges and API endpoints for programmatic status access
• Internationalization support for multilingual status pages
