Unified observability, security and incident response for cloud-scale engineering teams
Agents, cloud integrations and OpenTelemetry collectors feed one platform where metrics, distributed traces, profiles and logs can be pivoted between without context switching.
Bits AI, an agent builder and LLM/AI-agent observability help teams triage alerts, explain anomalies and monitor model latency, token spend and agent traces.
Cloud SIEM, cloud security posture management, vulnerability management, workload protection and code scanning correlate threat signals with the telemetry you already collect.
Real user monitoring, session replay, product analytics, synthetic and mobile testing sit alongside CI visibility, test optimization, feature flags and DORA metrics.

Capture, debug, and replay failed webhooks before your users notice
Each endpoint gets a HookWatch URL that receives and forwards webhooks, recording status, provider, response code, latency, and attempt count for every delivery.
Re-send an exact captured payload after a fix, with manual replay and retry policies instead of recreating the event by hand.
Failed deliveries are categorized by reason — signature mismatch, timeout, 5xx, rate limit — so you know what broke without grepping logs.
Recurring failures group into a single incident routed to Slack or a webhook, so a flaky endpoint shows up as one problem.
