Who should pick which
- QSR chain operatorPick: Presto Voice
Presto Voice automates drive-thru ordering, boosts revenue via upselling, and integrates with existing POS/headsets, as evidenced by Dairy Queen adoption. Herm is irrelevant for this use case.
- Privacy-conscious terminal developerPick: Herm
Herm's containerized sandbox prevents host system access, supports local models (Ollama), and is open-source – ideal for developers who prioritize security and transparency.
- Small independent restaurant with limited budgetPick: Herm
Not a direct fit, but Herm is free while Presto requires custom pricing. For coding tasks, Herm wins; for drive-thru, neither is suitable – the restaurant needs a lower-cost alternative.
- DevOps engineer managing multiple AI agentsPick: Herm
Herm's Fleet console (latest news) and multi-provider support enable scalable agent workflows in Docker, making it a strong choice for agent orchestration.
- Franchise network wanting standardized voice AIPick: Presto Voice
Presto's menu unification and scalable deployment across locations fit franchise needs; latest partnership with Dairy Queen confirms enterprise-level adoption.
