What real users say: Proxy vs Presto Voice

Not marketing copy and not our opinion — a structured sweep of public discussion (reviews, forums, communities and video comments), showing what people praise and what they complain about for each tool.

Proxy

105 mentions across 6 sources · 8% positive — critical (averaged across 6 sources)

Hacker News, Product Hunt, App Store, Bluesky, Stack Overflow, Lemmy

What users praise

  • • Open-source MIT license allows full code transparency and customization.
  • • Local proxy adds zero latency overhead (~6ms) and no cloud dependency.
  • • Smart model routing cuts API costs by assigning cheaper models to simple tasks.
  • • Multi-credential pool avoids rate limits by round-robining across keys.

What frustrates them

  • • No community feedback available to verify claimed features or reliability.
  • • Telemetry on by default may conflict with local-first privacy expectations.
  • • Response cache is exact-match only, limiting benefit for varied prompts.
  • • Dashboard requires localhost access; no cloud monitoring option.

Presto Voice

37 mentions across 3 sources · 32% positive — critical (weighted across 3 sources)

YouTube, App Store, Lemmy

What users praise

  • • Handles POS and headset integration itself, so voice AI goes live in an active lane without pausing service
  • • Built specifically for multi-location QSR franchise groups, not single shops or dine-in concepts
  • • Continuous upselling of add-ons and specials on every transaction targets average-order-value lift
  • • 24/7 drive-thru ordering availability removes the labor constraint of shift coverage at the speaker post

What frustrates them

  • • Almost no independent, on-topic community reviews — the dataset is dominated by unrelated same-name products
  • • Vendor-published KPIs (95% non-intervention, 88% upsell, 6% lift) lack third-party verification
  • • Won't hand over the model to tune, which blocks teams that want to own and iterate on the voice stack
  • • Only Toast is documented as a named POS integration in the available data
