Docker Launches Cloud Sandboxes, Extending Secure AI Agent Isolation Beyond the Laptop
Docker, Inc.®, the trusted platform for building software in the agentic era, today announced Docker Cloud Sandboxes, a new solution for secure, isolated AI agent execution that enables complex agentic workflows to continue running in the cloud long after a developer's laptop shuts down.
OpenAI Updates Agents SDK with Native Sandboxes
OpenAI updated its Agents SDK to add sandboxing and an in‑distribution harness to help enterprises build safer, more capable agentic applications. The sandbox integration lets agents operate in siloed workspaces with controlled access to files and approved tools, reducing risks from unsupervised execution. The new harness supports deploying and testing agents on frontier models and aims to enable long‑horizon, multi‑step workflows. OpenAI said the harness and sandbox features are launching first in Python, with TypeScript support planned later, and that the capabilities will be available to all customers via the OpenAI API at standard pricing. The company intends to expand the SDK over time with features such as code mode and subagents to help move agents from prototype to production.
Persistent Sandboxes for AI Code Execution
A developer post by Arun Raghunath (published 2026-06-05) argues for persistent sandboxes as a better execution model for AI-generated code. The post describes Jhansi.io v0.2, which replaces disposable containers with per-sandbox persistent workspaces on disk, a file upload API, and an exec-by-filename model. The persistent workspace enables multi-file projects, delta sync (uploading only changes), and automated dependency detection. The author positions this architecture as foundational for safely running AI agents that generate and execute code and invites design partners for early access.
