OpenAI Acquires Ona for Persistent Agent Sandboxes — Multi-Day Autonomous Coding Arrives

OpenAI acquired Ona (formerly Gitpod) on June 11 for approximately $79 to 100 million, gaining persistent containerized development sandbox infrastructure that enables Codex agents to run continuously across multi-day tasks.

Ona's core capability:

• Persistent, containerized development sandboxes maintaining state, environment context, filesystem access across extended multi-day sessions • Customer-controlled VPC environments — enterprise code and credentials never leave the customer's cloud boundary • Solves the fundamental limitation of AI coding agents losing all context when sessions end

Enterprise implications:

• Codex can now accept long-horizon tasks: multi-day refactoring, continuous integration monitoring, background test generation • No requirement for human re-engagement to restart sessions and restore context • Integration expected in Q3 2026 as the default execution environment for Codex Enterprise

The Ona acquisition completes the technical stack for enterprise autonomous coding agents: capable reasoning model (GPT-5.5/Codex), persistent execution environment (Ona), payment integration (Visa), and growing enterprise tool integrations. This is the moment Codex transitions from a developer productivity tool to an enterprise AI workforce platform.

Engineering teams can now assign project-scale work and have Codex execute it in the background over multiple days while engineers focus on architecture and review.

Why It Matters: Persistent sandboxes fundamentally change the task assignment model for AI coding agents. Instead of single well-defined tasks, engineering teams can assign project-scale work that executes autonomously over multiple days.
