Is Scalekit worth the price?
65/100
Scalekit's current pricing, with only a 'Free' tier publicly available, makes it difficult to assess overall fairness or value.
While a free tier is generous for initial exploration, the lack of transparent paid options means potential users cannot compare costs or features for scaling. This structure is best for early-stage AI projects and developers looking to experiment with AI authentication without immediate financial commitment.
