Who should pick which
- Solo founder building an AI agentPick: Iii
III's free, local-first, and simple primitives allow fast iteration without cloud costs. Agents are first-class workers, and the engine handles retries/state out-of-the-box.
- Enterprise team orchestrating microservices with rollbacksPick: Temporal AI
Temporal's Saga pattern, automatic retries, and human-in-the-loop signals are proven for financial systems and multi-step transactions. Cloud support provides SLA and observability.
- Platform team shipping internal capabilities as workersPick: Iii
III's `iii worker add` command and polyglot support let platform teams expose capabilities quickly. Cross-language calls and unified observability ease integration.
- Developer building event-driven, multi-language systemPick: Iii
III's three primitives reduce complexity; workers in Node.js, Rust, Python, Go can coexist. Its event loops, cron, and WebSocket triggers suit event-driven architectures.
- Team needing managed durable execution for AI pipelinesPick: Temporal AI
Temporal's durable execution is battle-tested at OpenAI, Lovable, etc. Serverless Workers and integrations with AI SDKs reduce operational burden. Usage-based billing offers cost flexibility.
