User sentiment across GetApp and G2 is strongly positive, with reviewers consistently praising ease of setup, clear segmentation capabilities, responsive customer support, and the security assurance of self-hosting. Enterprise users highlight audit logs, Terraform integration, and OpenFeature compatibility as standout strengths.
