About Oack
Oack is an external HTTP monitoring service built for engineers who need to diagnose latency and outages, not just detect them.
Every probe captures:
- 6-phase HTTP timing breakdown (DNS, Connect, TLS, Send, Wait, Receive)
- TCP kernel telemetry — RTT, retransmits, congestion window, RTO via getsockopt(TCP_INFO) on Linux
- Server-Timing header automatic capture and visualization
- Cloudflare CDN log enrichment (edge PoP, cache status, origin response time)
- Traceroute with per-hop RTT, ASN, and geolocation
- Performance percentiles across 1d, 7d, 30d, 90d windows
- Optional packet capture (PCAP) for deep post-mortem analysis
Browser monitoring with Playwright — both Pageload mode (Web Vitals, HAR waterfall, screenshots) and Test Suite mode (run your existing .spec.ts files as scheduled monitors).
Built-in incident management — automatic incident creation, on-call scheduling with rotations, escalation policies, war rooms, post-mortem reports.
