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.
Steer SDK features
- Low-latency sidecar. Adds verification with less than 5 ms overhead by running in-process.
- Fail-safe design. Configurable behavior on internal errors to prioritize uptime.
- Zero data exfiltration. Local-first architecture ensures prompts never leave your network.
- Audit-ready logging. Every blocked response is logged with a deterministic reason code.
- Framework patching. Zero-touch reliability for frameworks like PydanticAI via a central policy file.
- Decorator sidecar. Manual control using @capture decorator to inject taught rules at runtime.
