How do you run multiple coding agents today?

I built ManyAgents because I kept losing track of 10+ agents across projects. I'd love to learn how others handle it:

1. How many agents do you usually run at once, and across how many projects?

2. What breaks first: keeping track, merge conflicts, usage limits, or reviewing the work?

3. What would you pay for a tool like this: one-time, monthly, or not at all?

Every answer helps shape what I build next. Thanks!
