Open Responses Server vs Temporal AI
Side-by-side comparison of features, pricing, and ratings
At a glance
| Dimension | Open Responses Server | Temporal AI |
|---|---|---|
| Pricing | Free, open-source MIT | Freemium: Temporal Cloud usage-based billing |
| Deployment | Self-hosted (pip install) | Self-hosted or Temporal Cloud |
| Primary Use Case | OpenAI Responses API compatibility layer for any LLM backend | Durable execution, stateful workflows, AI agents with crash recovery |
| State Management | In-memory multi-turn conversation history | Automatic state capture and persistence across steps |
| Tool Execution | Tool call execution loop with iteration limits | Activities with retries, timeouts, human-in-the-loop |
| AI Agent Support | Compatible with Codex CLI and Responses API clients, no built-in agent reliability | Durable AI agents with crash resilience, integration with OpenAI Agents SDK and Google ADK |
If you need a durable, fault-tolerant platform for long-running AI workflows that survive crashes, choose Temporal AI. For a lightweight, free compatibility layer to run Responses API agents with local models like Ollama, go with Open Responses Server. They solve different problems: one is an orchestration engine, the other an API adapter.

What users praise
- • Bridge any OpenAI-compatible backend to the Responses API, enabling Codex CLI locally.
- • MCP server support for both Chat Completions and Responses APIs expands tool use.
- • Stateful multi-turn conversations via in-memory history for agent workflows.
- • Configurable tool call execution loop lets agents iterate until completion.
What frustrates them
- • Duplicate /v1 in URL issue with vLLM shows base URL handling bugs.
- • Community support is nearly nonexistent; only 2 relevant GitHub posts found.
- • In-memory state is lost on restart, breaking long-running sessions.
- • Insufficient documentation for edge cases, relying on readme and sparse issues.

Who should pick which
- Solo founder building a reliable AI agent on a budgetPick: Open Responses Server
Free and easy to set up with local models; no cloud costs for experimentation.
- Enterprise team orchestrating multi-step financial workflows with rollbacksPick: Temporal AI
Durable execution, Saga pattern, automatic retries, and human-in-the-loop are critical for transactional reliability.
- Developer running Codex CLI with Ollama locallyPick: Open Responses Server
Perfect drop-in bridge to use Responses API with local models; lightweight and MIT-licensed.
- AI startup building crash-resistant agent pipelinesPick: Temporal AI
Temporal's state capture, retries, and integrations with OpenAI Agents SDK ensure agents survive failures.
- Self-hosted LLM user needing stateful multi-turn conversationsPick: Open Responses Server
Provides in-memory conversation history and tool call loops for quick prototyping; sufficient for non-critical use.
Frequently Asked Questions
Open Responses Server vs Temporal AI: which should you choose?
If you need a durable, fault-tolerant platform for long-running AI workflows that survive crashes, choose Temporal AI. For a lightweight, free compatibility layer to run Responses API agents with local models like Ollama, go with Open Responses Server. They solve different problems: one is an orchestration engine, the other an API adapter.
Which tool is better for production AI agents?
Temporal AI, because it provides durable execution with automatic state persistence, retries, and human-in-the-loop. Open Responses Server lacks durability and is better for prototyping.
Can I use Open Responses Server with Temporal?
Yes, you could use Open Responses Server as a lightweight API adapter inside a Temporal workflow activity, but Temporal itself can orchestrate the entire workflow.
Does Open Responses Server support streaming?
Yes, it supports SSE event streaming for real-time responses.
Is Temporal AI free to use?
The open-source server is free to self-host. Temporal Cloud has a usage-based billing model introduced in June 2026.
Which tool supports human-in-the-loop?
Only Temporal AI, via signals, pause/resume, and human-in-the-loop patterns.
Does Open Responses Server persist state across restarts?
No, it uses in-memory conversation history, so state is lost on server restart.
Can I deploy Open Responses Server in production?
Possible but not recommended as-is; it lacks rate limiting, authentication, and persistence. You would need to add those layers.
Does Temporal AI integrate with OpenAI Agents SDK?
Yes, as announced at Replay 2026, Temporal now integrates with OpenAI Agents SDK.
