Why people move off Fixie AI
- Smaller ecosystem than Twilio or some of the larger voice platform players
- Documentation depth varies; some advanced features are not well-documented
- Per-minute pricing can be hard to predict for variable-volume production workloads
- Less battle-tested at very high call volumes than older telephony platforms
Worth weighing against what it does well: strong engineering team with real speech AI backgrounds
