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

  • 3PL warehouse manager
    Pick: Locus Robotics

    High-volume, dynamic order profiles benefit from Locus's adaptive AMRs and Locus Array for autonomous fulfillment without facility redesign.

  • AI startup CTO
    Pick: Rhesis

    Free, open-source testing platform to catch LLM regressions before production. Self-hosted option fits security needs and tight budgets.

  • eCommerce operations director
    Pick: Locus Robotics

    Needs 2-3x productivity gains in picking and putaway. Locus integrates with major WMS and handles multi-level mezzanines.

  • Product manager for an AI chatbot
    Pick: Rhesis

    Can create natural language test cases collaboratively with domain experts, simulate adversarial scenarios, and trace failures.

  • Warehouse automation buyer on limited budget
    Pick: Locus Robotics

    RaaS subscription may be costly but delivers proven ROI. For low volumes, consider manual or simpler automation.
