Prefactor features
- Instant SDK integration. Drop-in TypeScript or Python SDKs (LangChain, Claude, Vercel AI, OpenClaw, LiveKit) instrument every agent call.
- Real-time run visibility. Shows full traces, latency, cost and data-risk for each token, tool call and decision as they happen.
- Custom evals & scoring. Run LLM-as-judge, technical checks and qualitative metrics on every step, with human-in-the-loop feedback.
- Runtime enforcement. Pause, approve or block risky actions automatically or via human review through SDK or API.
- Agent lifecycle management. Version, stage (dev/staging/prod) and promote agents only when evals pass, with instant rollback.
- Custom spans. Attach external data (GitHub, Jira, DB, APIs) to runs so evaluations are grounded in real context.
Traccia features
- Unified Agent Registry. Tracks all agents across LangChain, CrewAI, OpenAI Agents SDK and more without code changes.
- End-to-End Tracing. OpenTelemetry-native visibility into every LLM call, tool use and decision.
- Policy Monitoring & Enforcement. Three-tier guardrails that hard-block violations mid-execution.
- Cost & Token Attribution. Accurate per-model cost and token tracking, computed locally at span-end.
- PII & Sensitive Data Detection. Detects and masks personal data in traces before export.
- Prompt Registry & Playground. Versioned prompts with side-by-side evaluation and production promotion.
- Compliance Evidence. One-click export of audit-ready packs for EU AI Act and HIPAA.
- Analytics & ROI. Basic and advanced analytics, scheduled exports and an API for deeper insights.
