Helicone pricing and value

On the money side, Helicone starts at Free · paid tiers. A free plan means there is no reason to pay until you have confirmed it solves your problem; start there and upgrade only when you hit a real limit. Value is really a function of usage frequency — heavy users justify the cost easily, while light users often find a cheaper or free alternative does enough. Billing appears transparent in aggregated user reports, with no notable pattern of surprise charges.
