Codex gets a cloud sandbox——
OpenAI buys Ona (ex-Gitpod)
OpenAI has acquired Ona, a company born from Gitpod, to give Codex a secure cloud execution environment. The move pivots Codex from IDE autocomplete toward long-running autonomous coding tasks — closing the gap with Claude Code.
Codex's home was
the IDE autocomplete lane
Codex has been the core of GitHub Copilot and a recognised name in AI-assisted coding for years. Its primary domain was in-IDE code completion and inline suggestion — not the long-horizon, environment-aware autonomous execution that defines today's cloud coding agents. It lacked the secure sandbox for running code, managing filesystem state, and executing tests over extended sessions.
OpenAI has acquired Ona, a company spun from Gitpod, to add a secure cloud sandbox to Codex. The acquisition pivots Codex from IDE autocomplete toward long-running autonomous coding tasks in the cloud.
The sandbox is now
the heart of the agent
Coding agent differentiation has shifted from model quality to execution environment. Ona provides exactly the infrastructure layer that was missing.
Gitpod built containerised cloud development environments (CDEs) that let developers spin up isolated workspaces on demand. Ona adapted that technology for AI agent use, providing the secure, stateful execution environment that autonomous coding tasks require to run reliably over extended periods.
Claude Code gap narrows——
time to re-evaluate coding agents
Teams evaluating coding agents
Codex plus Ona is now a more serious option. Worth re-benchmarking alongside Claude Code before making a production commitment.

No reason to switch immediately, but monitoring Codex's progress at a regular cadence makes comparison decisions easier later.
