Frequently Asked Questions

Cymbal vs Temporal AI: which should you choose?

Temporal AI and Cymbal serve completely different needs: Temporal is a durable execution platform for building reliable, long-running workflows and AI agents with automatic recovery, while Cymbal is a CLI tool for fast code indexing optimized for AI agents' code comprehension. If you need resilience and orchestration, pick Temporal; if you need instant code navigation for agents, pick Cymbal. Both are free to start, but Temporal has a cloud option for scale.

Can Temporal replace Cymbal for code navigation?

No. Temporal is for workflow orchestration, not code indexing. Cymbal is purpose-built for fast AST-based code queries.

Does Cymbal support durable workflow execution?

No. Cymbal is a code indexer with no workflow capabilities.

Is Temporal free?

Yes, Temporal Server is open-source and free to self-host. Temporal Cloud offers a free tier with usage-based pricing.

How many languages does Cymbal support?

24 languages including Go, Python, TypeScript, Rust, C, Java, Ruby, Swift, Kotlin, Scala, PHP, etc.

Which tool is better for AI agent development?

Both: Cymbal for code understanding, Temporal for reliable agent orchestration. They can complement each other.

Does Temporal integrate with Cymbal?

There is no direct integration. Cymbal could be used within a Temporal workflow to index code, but no native support.

What's the latest news about Temporal?

June 2026: Temporal introduced usage-based billing for better cost transparency and a Billable Action Count metric.

What's the latest news about Cymbal?

No recent news captured; Cymbal appears stable as a free CLI tool.
