Everything you love about Kuma, without the ops.

Uptime Kuma checks from wherever you host it — one server, one location, one perspective on the internet. If your VPS provider has a network hiccup, you get a false alarm. If your Kuma server goes down with the rest of your infrastructure, you get nothing at all.

This isn't a niche concern. Multi-location monitoring has been the most requested feature in Uptime Kuma's GitHub issues since 2021, and it's still not implemented. Larm checks from six probe locations across three continents and only alerts when a majority confirm the problem. A network issue in one region doesn't wake anyone up.

Self-hosting Uptime Kuma means you're responsible for a server. Updates, backups, disk space, uptime of the monitoring tool itself. Users report SQLite databases growing past 800MB after a few months, dashboard load times of 15+ seconds at 500 monitors, and single-threaded CPU bottlenecks under load.

And there's the fundamental paradox: who monitors the monitor? If the server running Kuma goes down alongside your services, you find out when your customers do. Larm is a managed service — we handle the infrastructure, the scaling, and the reliability. You just add your endpoints.

Uptime Kuma is single-user. There's no way to invite your team, no role-based access control, no shared configuration. Multi-user support has been requested since 2021 and remains unimplemented. If you're a team of more than one, you're sharing a single login.

Larm has team seats from day one. Invite your team, share monitors and alert configurations, and manage access. The free tier includes 1 seat — invite your first teammate by upgrading to Pro, which gives you 10.

Uptime Kuma's status page runs on the same server as Kuma itself. If that server goes down — which is exactly when your customers need to see a status page — the status page goes down too.

Larm's status pages are static HTML served from a CDN, completely independent of the monitoring platform. Your infrastructure can be on fire and your status page will still be up, showing your customers exactly what's happening.

Uptime Kuma gives you basic response time charts and uptime percentages. It's useful, but it's surface-level.

Larm stores every check result in ClickHouse with full timing breakdowns — DNS, TCP, TLS, TTFB, transfer — and computes percentile analytics (p50, p95, p99) over any time range. You get geographic performance breakdowns, trend analysis, and an analytics explorer for ad-hoc queries. When something degrades, you see exactly which phase, from which location, and how it's trending.

Uptime Kuma doesn't have a public REST API. It uses Socket.IO internally, which means there's no clean way to automate monitor creation, integrate with CI/CD pipelines, or manage your monitoring config as code. The maintainer has explicitly said the project is focused on being a UI-based tool.

Larm has a read and write REST API and a built-in MCP server. Automate monitor creation from your deployment pipeline, manage monitors and incidents from Claude Code or Cursor, or build custom dashboards through code.
