Agent Studio is Arize AI's managed platform for configuring and running custom AI agents. Agents can be created from scratch or from templates such as Signal and a cost agent, connected to projects containing traces, assigned tasks, and given skills such as GitHub or Datadog integrations. They run in managed sandboxes. Arize describes its broader platform as supporting agent observability, evaluation, tracing, experimentation, and continual improvement; in the demonstrated workflow, Signal reads traces on a schedule, files deduplicated issues, and turns failures into evaluation cases and regression datasets for experiments and fixes.

Workshop Studio is a hosted Jupyter notebook environment with pre-created AWS accounts for building and testing an agent. In the described workshop, it hosts notebooks for developing a customer-service agent with Strands Agents, testing tool-call controls, adding skills and steering handlers, and preparing deployment to Amazon Bedrock AgentCore.

Agent Substrate is an open-source runtime and control plane for running agent-like workloads at high density. It manages the lifecycle of sandboxed actors, including creation, destruction, suspension, and resumption, and assigns them to a smaller pool of worker pods while routing traffic to the active workers. The system uses Kubernetes for infrastructure provisioning and pod lifecycle management, with support for sandbox technologies including microVMs and gVisor. It preserves actors' volatile memory and filesystem state through full-state snapshots, enabling sub-second suspend and resume operations and multiplexing many stateful actors across shared infrastructure. It manages standard OCI containers at the kernel level and is designed to support different agent frameworks and harnesses, including ADK-compatible actors, LangChain agents, coding environments, and MCP servers. Agent Substrate is intended for running agents at scale rather than building them, and its workloads do not have to be literal AI agents. The repository notes that the project is not an officially supported Google product.

Kubernetes-sigs Agent Sandbox creates isolated, disposable environments for running untrusted or agent-generated code. It is intended to separate such code execution from other workloads.

Standard Agent Builder is a runtime for the Standard Agent Specification. It lets users create and run standard agents locally at no cost or deploy them to the cloud, with administrative views of agent threads, tool calls, model usage, and costs. The runtime is intended to support portable agents that can be distributed and composed with other agents.
