Who should pick Sayna, and who should pick Locus Robotics?

  • Warehouse Manager at a 3PL
    Pick: Locus Robotics

    Locus Robotics' AMRs and Locus Array boost picking productivity 2-3x for high-volume eCommerce and retail operations.

  • AI Engineer Building Voice Agents
    Pick: Sayna

    Sayna's unified API abstracts TTS/STT/VAD, integrates with LangChain, and supports multi-provider swapping without code changes.

  • Small Warehouse Owner
    Pick: Locus Robotics

    Not ideal: RaaS pricing may not justify ROI for low daily order volumes, as noted in not_for.

  • Non-Developer Using No-Code Tools
    Pick: Sayna

    Not recommended: Sayna targets developers; no-code voice solutions are not its focus.

Frequently Asked Questions

Can Locus Robotics be used in narrow aisles?

No, it is not recommended for extremely narrow aisles where AMRs cannot navigate.

Does Sayna support phone system integration?

Yes, it has a built-in SIP server for phone system integration and tenant-based SIP routing.

Is Locus Robotics suitable for small warehouses?

Typically not, as RaaS costs may exceed ROI for low-volume orders.

What frameworks does Sayna work with?

It is framework-agnostic, with explicit integrations for PydanticAI, LangChain, and LlamaIndex.

What recent update did Locus Robotics announce?

In May 2026, they launched Locus Array, enabling fully autonomous fulfillment (picking, putaway, etc.).

Does Sayna provide call recording?

Yes, it offers call recording, retrieval, and search at scale, as highlighted in Dec 2025 news.

Can Locus Robotics integrate with my WMS?

Yes, it integrates with SAP, Manhattan, Blue Yonder, Oracle, and many others.

Is Sayna open source?

No, but its architecture supports open-source voice models (e.g., Nemotron ASR) from Jan 2026.
