Does Euphony require a server?
No, it runs entirely in the browser with no backend. You can also self-host via GitHub Pages.
Can Temporal AI be used for non-AI workflows?
Yes, it's a general-purpose durable execution platform used for microservices, CI/CD, and financial systems, not just AI.
Does Euphony support real-time monitoring?
No, it's designed for post-hoc analysis of static log files, not live streaming.
What SDKs does Temporal AI support?
Python, Go, TypeScript, Ruby, C#, Java, PHP, and Rust (public preview).
Can I export visualizations from Euphony?
Yes, you can export the timeline as static HTML or PNG snapshot.
Does Temporal support human-in-the-loop?
Yes, via signals, pause/resume, and the built-in visibility UI.
