Who should pick which
- Solo founder prototyping multi-agent appPick: Arch
Arch is free, open-source, and easy to set up as a sidecar for routing and safety. No cloud costs or complex SDKs needed.
- Enterprise building financial transaction workflowsPick: Temporal AI
Temporal's durable execution with saga pattern and automatic retries ensures reliability. Cloud option provides SLAs and support.
- AI agent team requiring guardrails and observabilityPick: Arch
Arch provides zero-code agentic signals, OTEL traces, and jailbreak protection without modifying agent code.
- Platform team orchestrating microservices with long-running processesPick: Temporal AI
Temporal's Workflows and Activities handle multi-step orchestration with state persistence. Recent Serverless Workers reduce operational overhead.
- Startup needing both durable execution and agent routingPick: Temporal AI
Temporal can orchestrate the durable parts; you can still use Arch alongside for routing. Temporal's broader SDK support and visibility UI offer more comprehensive capability for core logic.
