Answered from the vendors’ own pages

SourceMicrosoft Power Automate: How many flow runs are allowed on the free plan?
Power Automate's free tier (included with Microsoft 365) is limited to 750 flow runs per month and standard connectors only. Out of 900+ total connectors, the free plan only includes Microsoft ecosystem apps and limited third-party apps.
SourceMicrosoft Power Automate: What's the difference between Premium and Process plans?
Premium ($15/user/month) provides attended automation with cloud flows and standard RPA. Process plan ($150/bot/month) enables unattended automation where bots run without human intervention on virtual machines for high-volume, repetitive tasks.
