| Key features | - OpenTelemetry-native LLM tracing for every call, tool, and retrieval
- Agent evals with LLM-as-a-judge and heuristics
- Prompt Hub for versioning and deployment without code changes
- Guardrails for prompt injection, jailbreak, and sensitive topic detection
- Vault for encrypted API key management
- 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
| - Verify arbitrary diffs from agents, codemods, or humans
- Three-verdict system: SAFE, UNSAFE, UNPROVEN
- Runs test suite on isolated shadow tree copy
- Changed-line coverage attestation for Python
- Reproducible verification report with audit-grade record
- MCP server for AI agents to verify before landing
- CI gate that blocks unsafe merges
- Syntax and imports validation gates
- Runs locally with no code upload to external service
|

| 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
| - Only system that proves changed lines are actually tested, not just that tests pass
- Works with any AI coding agent and integrates via MCP
- Code never leaves your machine; runs entirely locally
- Free local CLI with unlimited verifications, paid only for managed infrastructure
