Play by Hyperspace

Play by Hyperspace is a browser-based AI environment for building, testing, and sharing autonomous AI agents and workflows. It provides a visual, node-based interface where users can connect language models, tools, APIs, and data sources into structured “plays” that execute complex tasks end to end. The platform supports multi-step reasoning, branching logic, and conditional flows, enabling users to design agents that can plan, act, and adapt based on context and intermediate results.

Key capabilities include an interactive canvas for composing workflows, integrated support for major LLM providers, and the ability to attach external tools such as web search, code execution, and custom APIs. Users can inspect intermediate outputs, debug behavior, and iteratively refine prompts and logic. Versioning and sharing features allow teams to collaborate on agent designs and reuse components across projects.
