OpenAI acquires Ona (formerly Gitpod) — cloud sandboxes for long-running Codex agents; team joins the Codex division

What was announced

The reporting from OpenAI’s official announcement, Bloomberg, CNBC, SiliconANGLE, and Techzine confirms:

• Acquirer/target: OpenAI is acquiring Ona (officially Gitpod GmbH, founded Kiel, Germany, 2020; rebranded from Gitpod to Ona in 2025)
• Terms: not disclosed
• Team destination: the Ona team joins the Codex division
• What Ona does: cloud-based, persistent sandboxes where AI agents research, write code, run tests, and implement changes — environments that stay online when the developer’s workstation shuts down
• Scale: Ona reports ~2 million developers have used its secure, reproducible cloud environments
• The usage disclosure: Codex now has 5M+ weekly users, up 400% from earlier this year

Why Ona specifically

Codex’s product philosophy — delegate a task, come back to a finished PR — has one hard infrastructure dependency: the agent has to keep running when you’re gone. Local-first tools tie agent lifetime to the developer’s machine. Ona’s entire product is the inverse: sandboxes that persist independently, with more compute than a workstation and security isolation that enterprise procurement teams accept.

That maps directly onto what OpenAI says it bought the company for: extending Codex’s ability to perform long-running tasks that take hours or days. The multi-agent Codex v2 workflow — parallel agents fanning out over a backlog — gets materially better when each agent has a durable, reproducible environment instead of an ephemeral container.

Why this matters

Three reads.

1. The async-delegation lane is now an infrastructure race. Claude Code won the interactive lane — 46% “most-loved” in the JetBrains April 2026 survey, reinforced by Fable 5’s launch endorsements from Cursor and Cognition. Codex’s counter-position has been async delegation since the GPT-5.3-Codex era. Buying Ona converts that positioning from a model behavior into owned infrastructure — harder for competitors to replicate with a fine-tune.

2. The 400% growth number is the real headline for the market. 5M+ weekly Codex users (from ~1M earlier this year) is the first hard usage figure OpenAI has attached to Codex. For context, that growth happened while Anthropic overtook OpenAI in U.S. business adoption on Ramp’s index — the coding-agent market is expanding fast enough that both leaders are growing simultaneously.

3. European AI startups remain acquisition targets, not IPO candidates. Ona is one of Germany’s most prominent dev-tools startups, and its exit is a talent-and-technology absorption into a U.S. lab — a familiar pattern, and one EU policymakers watching the Apple/DMA standoff will notice.

What it means for Codex users and the coding-tools market

For Codex users: expect the “walk away” workflows to get longer and more reliable — multi-hour refactors, overnight test-coverage runs, multi-day migrations. That’s the explicit integration goal.

For Gitpod/Ona customers: no migration timeline has been published. With the team joining Codex, standalone Ona product development is likely to slow; teams depending on it should watch for continuity commitments before renewing contracts.

For the Claude Code vs Codex decision: the two-philosophy split sharpens. Interactive, reasoning-heavy work → Claude Code (especially with Fable 5 free through June 22). Delegation at scale → Codex, now with owned sandbox infrastructure. The “most pros run both” conclusion in our best AI coding tools guide stands.

For Devin and Windsurf: Cognition’s “plan locally, execute in cloud” pitch just got a far better-resourced competitor. Cognition’s reported $25B raise suddenly looks defensive as well as offensive.

The honest caveats

Terms are undisclosed, so the deal’s scale signal is unknown — this could be an acqui-hire or a major infrastructure purchase; the difference matters and isn’t public.

The 400% growth figure is OpenAI’s own, disclosed alongside an acquisition announcement — exactly when a company is most motivated to show momentum. No independent verification of weekly-user methodology exists.

Integration risk is real. Gitpod’s 2025 rebrand to Ona was itself a pivot; the team now faces a second strategic redirection in under a year inside a much larger organization.

What it changes for Pick Right readers

If you’re a Codex user: nothing today; meaningfully longer agent runs over the coming quarters.

If you’re an Ona/Gitpod customer: start contingency planning now, before renewal.

If you’re choosing a first AI coding agent: the Claude Code vs Codex comparison and the coding tools guide both remain current — this deal reinforces their core framing rather than overturning it.
