- OpenGround for side-by-side LLM model comparison
- GPU monitoring for utilization, memory, temperature, and power
- Coding agent observability for Claude Code, Codex, and Cursor
- Cost tracking and latency monitoring
- 56+ integrations with LLMs, frameworks, and vector databases
| - Risk scan of agent reach, capabilities and consequences
- Policy-as-code for gating rules
- Shadow mode to preview holds before enforcement
- Human-in-the-loop approvals via console
- Cryptographically signed audit ledger
- Compliance framework packs

| What makes it different | - Self-host free forever under Apache 2.0 with unlimited usage and no per-trace fees
- OpenTelemetry-native traces exportable to Grafana, Datadog, or any OTLP backend
- Zero-code instrumentation with eBPF controller, native SDKs, or GPU collector
- Unified platform for traces, evals, guardrails, and prompts on the same production data
- Full data ownership and no vendor lock-in with exportable OpenTelemetry traces
| - Gates actions, not agents—routine calls pass through untouched
- Low published latency overhead: p50 8ms, p95 25ms for allowed verdicts
