The open-source Uptime Kuma upgrade
Your monitoring shouldn't be
a single point of failure.
Production-grade open-source monitoring — built in Go, distributed by design, with a modern UI your team will actually enjoy using.
Built for production, not for side projects
Dogfooding
We run Warden on our own infra.
Live data. Warden monitors projecthelena.com from us-east, eu-west, and ap-south simultaneously. If any region disagrees, we investigate before alerting.
This is multi-zone monitoring. Not one server hoping for the best.
Why Teams Switch to Warden
Every feature solves a real problem.
No silent outages
3+ regions
Multi-zone checks mean one server dying never leaves you blind.
Go, not Node.js
10x less memory
Single binary, native concurrency. Uses fewer resources than what it monitors.
No per-seat pricing
Unlimited users
Every plan includes your whole team. No surprise bills as you grow.
10-second checks
30x faster
Most tools check every 5 minutes. Warden catches issues in seconds.
Self-host or cloud
Same codebase
Start on a $5 VPS. Upgrade to managed cloud with zero migration.
Modern UI
Built for 2026
Clean, fast, and pleasant to use at 3am. Designed like Vercel and Linear.
How Warden Compares
The upgrade path from Uptime Kuma.
Same open-source philosophy. None of the limitations.
| Feature | Warden | Uptime Kuma | Typical SaaS |
|---|---|---|---|
| Architecture | Distributed multi-zone | Single server, single process | Cloud-only |
| Language | Go (10x less memory) | Node.js | Varies |
| Check interval | Down to 10 seconds | 20 seconds | 1-5 min (free tiers) |
| Monitoring regions | Multi-zone (Cloud) | 1 (wherever hosted) | 4-22 (enterprise only) |
| Team members | Unlimited, every plan | Single user only | $5-41/user/mo |
| SSO | Google SSO included | No (2FA only) | $300+/mo tier |
| Managed cloud | Yes, from $49/mo | No | Only option |
| Self-hosted | Yes, free forever | Yes, free | No |
| API | Full REST, documented | Socket.IO only (community) | Usually available |
| License | AGPL | MIT | Proprietary |
Open Source
Start self-hosted.
Scale to cloud. Same codebase.
Warden is AGPL-licensed. One Docker command, and you're monitoring in under a minute. When you outgrow a single node, upgrade to Warden Cloud — same software, no migration.
Pricing
Simple. No per-seat nonsense.
Every plan includes unlimited team members. Because charging per seat for monitoring is absurd.
