Does this stop you from using Cursor

Yes - Cursor is unusable

Hey, thanks for the report. Background Agents (which power Cloud Agents) are a Pro feature and aren’t included in the free Hobby plan. The one-week Pro trial that comes with Hobby may also have some limits on which Pro features are available.

Could you check your subscription status at Cursor - The AI Code Editor? This will help clarify:

  • Are you on the Hobby plan with a Pro trial?
  • Or do you have an active Pro subscription?

If you have an active Pro subscription and still see this error, that does look like a bug. The message mentioning “Pro+” is also confusing, since Background Agents are supposed to work on regular Pro.

I don’t see anything about the hobby plan, but it does say “pro trial,” yes.

To be fair, Cursor’s behavior is very weird for me. For example, my friend on a hobby plan could use the agent multiple times a day after reaching his limits, while for me, the limits didn’t refresh at all.

I can’t find any bars with “500 requests” limit.

I don’t understant why i have 10$ limit on upgraded models, will this refresh or not for full pro.

I don’t undersrtand when cloud agents become available (should be pro? but error says pro+).

And all of that type of stuff.

I would add some text to pop-up that users see tho but may be it’s missing because of 500 internal server error.

Thanks for the info. I see Cloud Agents (Background Agents) aren’t working - 500 Internal Server Error: “You’ve reached the limit for your trial. Upgrade to Pro+”.

This isn’t a bug - Cloud Agents is a Pro feature, available on Pro/Business plans. The Pro trial (1 week) might have limits. Trial versions don’t count toward main limits, but trials can have their own restrictions.

Check subscription status: Cursor - The AI Code Editor - you’ll see if you’re on Hobby with Pro trial or active Pro. If Pro is active but error persists, let me know.

Workaround:

  • If trial ended - upgrade to Pro
  • Or use regular Agent instead of Cloud Agents.

If Pro is active, send a dashboard screenshot - I’ll check.

Share subscription info.
