Is Cerbos worth the price?
Good value
Cerbos offers a generous free tier and a Proof of Concept plan, making it highly accessible for evaluation and small-scale use.
The jump from the free PoC to the $25/month Development tier is reasonable, but the leap to the $933/month Production tier is significant, indicating a strong focus on enterprise-level customers. This pricing structure is best suited for startups and mid-sized companies scaling into enterprise, and large organizations requiring robust authorization.
