I've been using the xstate inspector with xstate 4 and I'm now getting "This deployment is temporarily paused" when going to https://statecharts.io/inspect. Apparently this is a vercel error message. Is the inspector not going to work anymore?

Wow that's the old old inspector!

This is also "legacy" but newer than that; have you tried it? https://github.com/statelyai/xstate-viz

Works with XState v4

I haven't tried it no, I'll see if that works. If nothing else, it's probably time to upgrade to xstate v5. I just hadn't been able to do it yet, but with AI it's probably much simpler now.

#

Looks like just setting url: 'https://stately.ai/viz?inspect' in the inspect configuration works without needing to change any libraries

Yep, all good?

#

Would still recommend updating to v5

#

If you use AI agents, just say "upgrade the machines and refer to https://stately.ai/docs/migration"
