Highlights

Monitor whatever you want

You can use Kuvasz to monitor a wide variety of endpoints: HTTP, SSL, Docker, DNS, TCP, ICMP (ping), push (cron), just name it, and you're covered!

Managing monitors
Built to scale

You can have 5 or 5,000 monitors, it doesn't make a difference! Kuvasz was built to perform in various scenarios, up until 1,000 monitors you'll be fine with the default configuration out of the box, and we have official recipes – proved by actual benchmarks – for everything above that.

Sizing guide
Notifications

Supports multiple notification channels, currently including email, Slack (via a webhook or a bot), Discord, Telegram, Microsoft Teams, Apprise, Pushover, PagerDuty and custom webhooks. You can configure the notification channels on a per-monitor basis.

Notifications
API

Provides a fully-fledged REST API to manage your monitors, check their status, and more.

API
Metrics Exporters

Export your metrics to Prometheus or to any OTLP-compatible tool, to integrate with your existing monitoring and alerting systems.

Home Assistant

Kuvasz has an official Home Assistant integration that allows you to easily integrate your monitors into your smart home setup, create custom dashboards, and automate actions based on the status of your services.

Home Assistant integration
Free & Open Source

Kuvasz is licensed under AGPL-3.0, it's free and it always will be.

Status Pages

You can create public and also private, brandable status pages for your monitors, to keep your customers or your internal team informed about the status of your services.

Status Pages
Maintenance Windows

Schedule planned downtime so Kuvasz pauses the affected checks and suppresses false alerts — manually, on a recurring cron schedule, or as a one-off event.

Maintenance Windows
Flexible Configuration

You can choose how you would like to manage your monitors: on the UI, or via the API, or with a single YAML file.

Flexibility
Cloud Native

Kuvasz is built with cloud-native principles in mind, distributed as a single Docker image, and only requires a PostgreSQL database to run.

Getting started
MCP server

Kuvasz ships with a built-in Model Context Protocol (MCP) server, which exposes your monitoring data and management operations as tools that AI assistants can call directly. This lets you query monitor status, view incidents, and create or toggle monitors through natural language — right inside Claude, Cursor, or any MCP-compatible client.
