Frequently Asked Questions

Vektori vs Temporal AI: which should you choose?

Choose Temporal AI if you need rock-solid failure recovery for AI agents or microservices orchestration with multi-language support. Choose Vektori if you're building a Python-based conversational AI that requires a long-term, graph-based memory layer to track user context and preferences. Both are open-source, but serve fundamentally different needs.

Can I use Temporal AI for simple cron jobs?

It's overkill; Temporal is designed for durable, long-running workflows, not simple scheduled tasks.

Does Vektori support languages other than Python?

No, Vektori is Python-only with no current plans for other SDKs.

Can Vektori be used with Temporal AI?

Yes, you could use Vektori as a memory layer inside a Temporal workflow for persistent context.

Does Temporal have a free tier?

Yes, Temporal Cloud offers a free tier with limited action rate; you can also self-host the open-source server for free.

Which tool has better out-of-the-box integrations?

Temporal AI integrates with OpenAI Agents SDK, Google ADK, Salesforce, Slack, etc. Vektori integrates with LLM providers and databases like Neo4j and Qdrant.

Is Vektori production-ready?

Yes, with production backends like PostgreSQL/pgvector, Neo4j, Qdrant, and Milvus.

What is the latest feature added to Temporal?

Serverless Workers (no worker management) and Standalone Activities were announced at Replay 2026.

Does Vektori have a cloud-hosted option?

No, Vektori is open-source and self-hosted only.
