Frequently Asked Questions

FlowTest vs Locus Robotics: which should you choose?

Choose Locus Robotics if you run a high-volume warehouse needing flexible AMR automation with proven 2-3x productivity gains — but be ready for ongoing RaaS costs. Choose FlowTest if you build and test API workflows and want a free, open-source IDE with natural language generation. They serve completely different domains, so your decision hinges on whether you need robots or API testing.

Can Locus Robotics work without human involvement?

No, its robots augment human workers but require associates for tasks like induction and quality checks; the Locus Array offers autonomous fulfillment but still collaborates with humans.

Is FlowTest only for OpenAI and AWS Bedrock?

No, it supports any OpenAPI-compliant API and integrates with multiple LLMs; OpenAI and AWS Bedrock are highlighted integrations.

What is the pricing for Locus Robotics?

It uses a RaaS subscription model with contact-based pricing; you must request a quote tailored to your warehouse needs.

Is FlowTest completely free?
