Is Oso worth the price?
Oso's pricing is fair, offering a generous free Developer tier for basic usage.
The jump to $500/month for the Startup tier is significant but includes critical features like increased events, auditing, and improved support. This structure is best for startups and growing businesses needing robust authorization and auditing without immediate enterprise-level customization.
