Open-Source Observability
Your infrastructure
deserves a war room.
Uptime monitoring and cost intelligence for teams that can't afford downtime. Built in Go. Deploy anywhere.
Built by operators, for operators
The Arsenal
Two tools. One mission.
Know when it's down. Know what it costs.
Uptime Monitoring
Your first line of defense. Know the second something goes down — not minutes later when customers start complaining.
- → HTTP, TCP, DNS, ICMP monitoring
- → 30-second check intervals
- → Multi-region validation
- → Slack, PagerDuty, webhook alerts
- → Public status pages
- → SSL certificate expiry tracking
Cost Intelligence
Your Kubernetes cluster is burning money and you don't know where. Recon maps every dollar to every namespace, pod, and workload — then tells you what to cut.
- → Namespace-level cost breakdown
- → Idle resource detection
- → Right-sizing recommendations
- → Budget alerts and forecasting
- → Multi-cluster support
- → Cloud-agnostic (EKS, GKE, AKS)
Situation Report
Don't take our word for it.
Helena monitors itself. Here's the live status of our own infrastructure — tracked by Warden.
Warden monitors Helena. Helena monitors you.
Why Helena
Built different, on purpose.
Go, not Node
Written in Go for raw performance and minimal resource usage. Your monitoring shouldn't need more RAM than your app.
No per-seat pricing
Flat-rate tiers. Add your whole team without doing budget math. $19/mo for Pro. That's it.
30-second checks
Most tools check every 5 minutes. That's 5 minutes of downtime nobody knows about. We check every 30 seconds.
Open source, for real
AGPL licensed. Read the code, audit the logic, self-host it. No vendor lock-in, ever.
Deploy anywhere
Docker, Kubernetes, bare metal, Cloudflare Workers. Your infra, your rules. Or use our managed cloud.
Multi-region validation
One region says it's down? We check from 3 more before alerting. Reduce false positives to near zero.
Open Source
Transparency is not a feature.
It's a requirement.
Helena is AGPL-licensed. You can read every line of code, audit the monitoring logic, and self-host it on your own infrastructure. No black boxes. No "trust us" security. Just code you can verify.
Pricing
Simple. No per-seat nonsense.
Every plan includes unlimited team members. Because charging per seat for monitoring is absurd.
