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 from our managed cloud. 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 cloud monitoring. Self-host for single-zone, or upgrade for multi-zone.
Why Teams Switch to Warden
Every feature solves a real problem.
No silent outages
Smart alerting
Confirmation thresholds, flap detection, and cooldowns mean you only get alerted when it matters. Multi-zone checks available on Cloud.
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

| Database | SQLite + PostgreSQL | SQLite only | Managed |
| API | Full REST + API keys | Socket.IO only (community) | Usually available |
| False alert prevention | Confirmation, flap detection, cooldown | Retry count only | Varies |

Built-in From Day One
The most requested features, already shipped.
These are the highest-voted open issues in Uptime Kuma. Warden ships with every one of them solved.
REST API
No way to manage monitors programmatically — every change requires the UI.
Warden: Full REST API with role-based API keys. Automate monitor creation from your CI/CD pipeline.
Multi-user & RBAC
Single-user only — no way to share access with your team without sharing one password.
Warden: Four roles built in: Admin, Editor, Viewer, and Status Viewer. Unlimited users on every plan.
Configurable uptime history
Status page shows a fixed, short time window. No way to show 30, 90, or 365 days of uptime.
Warden: Configurable uptime bar range from 1 to 365 days per status page.
PostgreSQL support
SQLite-only — database locked to a single file, no HA, performance degrades at scale.
Warden: SQLite by default for zero-config setup. Switch to PostgreSQL with one environment variable.
Single Sign-On (SSO)
No SSO support — another set of credentials to manage outside your identity provider.
Warden: Google OAuth SSO with domain restrictions and auto-provisioning. One click to sign in.
False alert prevention
Constant timeout false positives — you stop trusting your alerts.
Warden: Confirmation thresholds, notification cooldowns, flap detection, and recovery confirmation — all configurable.
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.
