The Monitoring Platform That Replaces Five Separate Tools
One dashboard. 14 check types. EU-hosted. Honest pricing.
Infrastructure monitoring with hawk-eye precision.
Teams are bleeding money on
monitoring sprawl
The average engineering team pays for 3–5 separate tools because no single platform covers everything.
| Tool you need | Typical vendor | Cost/mo |
|---|---|---|
| Uptime monitoring | Pingdom, Better Uptime | €15–€80 |
| Page speed / Core Web Vitals | Checkly, SpeedCurve | €50–€200 |
| SSL certificate tracking | TrackSSL, CertSpotter | €10–€50 |
| DMARC report analysis | dmarcian, Valimail | €50–€500+ |
| DNSBL / blacklist monitoring | MXToolbox, HetrixTools | €20–€100 |
| Total 5 separate tools | €145–€930+ |
…and you still don't have broken links, domain expiry, SSH monitoring, or synthetic transactions.
The monitoring market is
artificially fragmented
These are all the same job "is my infrastructure healthy?" yet the market forces teams to buy 5 tools.

Our thesis: One platform should cover all of this. So we built it.

Built to scale from day otdne
Purpose-built, not cobbled together from acquisitions.
| Layer | Technology | Why |
|---|---|---|
| API Gateway | Gin + gRPC | Dual protocol REST for web, gRPC for perf |
| Job Queue | NATS JetStream | At-least-once delivery, persistent, horizontally scalable |
| Database | PostgreSQL + TimescaleDB | Time-series optimized, 85+ migrations |
| Cache | Redis | Session store, rate limiting, warm chromium pool |
| Browser Engine | ChromeDP (headless Chrome) | Real rendering for page speed, synthetics, screenshots |
| Observability | OTel + Prometheus + Grafana | End-to-end tracing: API → NATS → worker → DB |

| GeoIP | MaxMind GeoLite2 | ASN + country resolution for DMARC and DNSBL |
Clean Architecture domain / application / infrastructure / interfaces separation. Every domain independently testable.
Simple, transparent pricing
No per-seat fees. No overage traps. DMARC volume spikes don't change your bill.

Six moats competitors
can't easily replicate
1. Unified scope
No other platform combines uptime + DMARC + DNSBL + page speed + synthetic testing. Competitors would need to build 3–5 new product lines.
2. EU-first, GDPR-native
Data stays in Europe. Every US competitor has GDPR as an afterthought we built it from day one.
4. Flat-rate pricing
Structurally cheaper for growing teams. Incumbents can't match without cannibalizing revenue.
5. Cloudflare Browser Rendering
Synthetic tests execute inside Cloudflare Edge, bypassing anti-bot challenges. Datadog and Checkly can't do this.
6. AI Diagnostic Reports
One-click DMARC health summary formatted for AI analysis. Hours of XML parsing → 30-second ChatGPT conversation.
