The Verdict
Fourthwall is built for youtubers and streamers, with a focus on merch-store and memberships. Polar targets open source developers and indie hackers and leads with subscriptions and one-time-payments.
Both tools use custom enterprise pricing — you'll need to contact sales for a quote, which makes direct cost comparison difficult.
Both offer free plans, so you can test each with your real workflow before committing to a subscription.
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.
