The Verdict
Prometheus is built for devops engineers and sre teams, with a focus on metrics-collection and alerting. The Trade Desk targets media buyers and agencies and leads with programmatic-buying and connected-tv.
Both tools use custom enterprise pricing — you'll need to contact sales for a quote, which makes direct cost comparison difficult.
Prometheus has a free plan, which gives it a meaningful edge for individuals and small teams exploring their options. The Trade Desk requires a paid subscription from day one.
This is a genuinely close comparison. If you can, sign up for both free trials (where available) and run a one-week test with your actual team tasks before deciding.
