Stash vs Presto Voice
Side-by-side comparison of features, pricing, and ratings
Stash or Presto Voice: which should you choose?
| Dimension | Stash | Presto Voice |
|---|---|---|
| Pricing | Free (open-source, self-hosted) | Contact sales (custom pricing) |
| Target Users | Developers building AI agents | QSR chains with drive-thrus |
| Primary Function | Persistent memory layer for AI agents | Voice AI for drive-thru ordering and upselling |
| Key Feature | Postgres-backed memory, MCP server | 95% non-intervention rate, upselling engine |
| Deployment | Self-hosted, single binary, offline capable | Cloud-based, integrates with POS/headsets |
| Best For | Developers needing vendor-free agent memory | Multi-location QSR chains wanting revenue lift |
Don't buy on the fence: Presto Voice is a specialized drive-thru AI for QSR chains wanting proven revenue lift (up to 6% monthly) and 95% automation — but it's contact-priced and not for non-drive-thru businesses. Stash is a free, self-hosted memory for AI agent developers, not a restaurant tool. Your choice depends entirely on your domain: either you run a multi-location QSR or you code autonomous agents.
Stash is a shared memory your connected AI tools can recall in the next conversation.
