CrewAI features
- No-code visual editor. Drag-and-drop canvas to design agentic workflows, exportable to Python.
- Role-based agents. Define distinct agent roles to simplify orchestration and ensure deterministic flows.
- Governance control plane. Real-time tracing, RBAC, audit trails, SSO and PII redaction for compliant execution.
- Continuous improvement. Automated and human-guided training turns production runs into training data.
- Multi-LLM testing. Swap models at runtime and evaluate performance with built-in metrics.
- Enterprise integrations. Supports GitHub, Slack/Teams, OpenTelemetry and can deploy to CrewAI cloud, VPC or customer infrastructure.
LangWatch features
- Scenario-driven simulations. Write plain-language scenarios that generate multi-turn conversations for agents.
- Red-team adversarial testing. Run adversarial simulations to surface jailbreaks, policy breaks and unsafe tool calls.
- Judge agent evaluation. LLM or custom judges score whole conversations with reasoning and pass/fail verdicts.
- Observability & tracing. Full OpenTelemetry-compatible traces of every token, tool call, cost and latency.
- CI/CD integration. Run simulations and evaluations locally or in pipelines on pull requests.
- Voice agent testing. End-to-end voice simulations with latency metrics and noise/interruption injection.
