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.

One key for 4,100+ agent tools, pay per call
A single treg token routes to 4,100+ endpoints across 127 providers, so no per-provider signups or scattered key files.
See each provider's price plus measured success rate, speed, and last-answer time, and pin a preferred vendor when you want.
Pay fractions of a cent per call with the price shown before you commit, no monthly seats required.
Route calls through your existing provider keys at no markup; credentials are injected server-side and never stored on a machine.
