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.

Crash care companion with error tracking, traces and real user monitoring
Ten issue types tracked with full stack traces, smart deduplication and affected-user tracking, from exceptions and slow queries to queue jobs and scheduler runs.
Core Web Vitals, sessions, JS errors, page loads, network timings and rage-click detection, with source map deobfuscation for readable traces.
A configurable rules engine that pushes alerts to Slack, Microsoft Teams, Telegram, webhooks or email, with acknowledgement and resolution history.
Data isolation per organization, team roles and permissions, grouped projects, invitations and complete audit trails.
