Where each one falls short
Documented limitations, not opinions. Every one is a constraint you would hit in normal use.
Flagsmith

- Enterprise-grade SSO and governance are locked behind the Scale-Up and Enterprise tiers.
- Self-hosting requires operating and updating the platform yourself, unlike a fully managed SaaS competitor.
Resemble AI
- The Team plan jumps to $350/month for just 5 seats, a steep increase from the free Flex tier.
- Detection accuracy rates (99.5% audio, 98% video, 96% image) mean some deepfakes can still go undetected.

- Voice cloning of another person's voice requires explicit consent verification, adding friction to some workflows.
