Calljmp features

  • TypeScript-native agents. Write agents and workflows directly in TypeScript with full type safety.
  • Managed execution & scaling. Calljmp handles agent runtime, state, retries, timeouts and HITL without infrastructure.
  • Observability dashboard. Unified traces, logs, metrics and cost tracking for all agents.
  • Zero-config integrations. Connect to REST/GraphQL/gRPC APIs, databases and services as tools without setup.
  • Human-in-the-loop. Add approval flows and manual reviews into any agent workflow.
  • Memory & knowledge store. Persistent context and vector/hybrid search for documents, APIs and datasets.

three.dev features

  • Live traffic scoring. Scores every production request in real-time with no added latency.
  • Failure mode grouping. Aggregates similar issues into named failure modes ranked by severity.
  • Evidence-backed issues. Each failure includes the exact line or prompt that caused it.
  • Coding-agent integration (MCP). Your coding agent can query failure modes and apply fixes automatically.
  • Before/after comparison. Compare metrics across two traffic slices to see impact of a fix.
  • Chat interface. Ask natural-language questions about traffic and get links to underlying requests.
  • Replay & experiment. Test new versions on recorded traffic before releasing to users.
