Visit WebsiteWho should pick Hermex, and who should pick Presto Voice?
- QSR franchise owner with 10+ drive-thru locationsPick: Presto Voice
Presto Voice is built for chains: it automates drive-thru order taking (up to 95% non-intervention), includes upselling to boost revenue, integrates with POS and headsets, and has proven ROI with brands like Dairy Queen and Taco John's. Recent Dairy Queen partnership confirms enterprise adoption.
- Solo developer running a self-hosted Hermes agentPick: Hermex
Hermex provides a native iOS interface for managing your agent remotely – stream responses, switch models, attach files – all without any third-party service. It's free and respects privacy. The latest Hermes Agent release with persistent memory enhances capabilities.
- Privacy-conscious homelab enthusiastPick: Hermex
Hermex connects directly to your self-hosted agent via Cloudflare Tunnel or Tailscale, has no analytics/tracking, and keeps all data on your server. The app's design philosophy aligns with self-sovereign AI.
- Restaurant operator with a single drive-thru and limited budgetPick: Presto Voice
While Presto Voice is enterprise-focused, even a single location could benefit from its automation and upselling – but pricing is opaque. Contact sales to see if it fits. For very small operations, simpler solutions may be more cost-effective.

Hermex delivers full agent control from iPhone with real-time streaming, file attachment, and reasoning settings. It requires technical setup, but fully eliminates third-party relays. A perfect match for those already using Hermes or similar open-source tools.
