Suno Free Tier (50 credits per day, no commercial rights)
Suno
Free starter tier ($0) with 50 credits per day, access to the official free models, standard features only; no commercial rights and no add-on credit purchases
Verbatim from the Free tier on the official pricing page: "Free: Our starter plan. $0. Access to our free models. 50 credits per day. Standard features only. No commercial rights. No add-on credit purchases"; only paid tiers get "Commercial use rights" and better models. The official Free vs Pro comparison table says Free corresponds to "Best free model (v6-mini)" and Pro to "Advanced models (v6 and v6-wild)".
Songs generated on the free tier carry no commercial rights, so be sure to upgrade your plan before using them in a commercial project. The page does not say how many credits one song costs, so "how many songs 50 credits per day buys" is unverified. Login methods (Google / Discord / email, etc.) were not checked one by one. Reachability from mainland China was not tested.
