Ona alternatives after the OpenAI deal

Why people look for an alternative

Ona announced that its acquisition by OpenAI closed on August 10, 2026 and that the team was joining OpenAI's Codex organization. The announcement did not describe post-close product or pricing changes, so uncertainty rather than a confirmed shutdown is the switching trigger. Ona's pricing page, checked September 4, 2026, lists no free tier: Core starts as a monthly OCU-based plan and Enterprise is custom. Existing customers may reasonably compare agent neutrality, infrastructure location and exit options before their next commitment, while avoiding the unsupported assumption that Ona will disappear or become Codex-only.

What to check before you switch

• Acquisition risk: separate announced facts from predictions. Evaluate current contracts, export needs and agent dependencies without assuming a future roadmap that OpenAI and Ona have not published.
• Workspace versus artifact: Ona provides cloud development environments and agents. Grain publishes finished output. A replacement may need the former, the latter or both.
• Agent choice: verify whether the environment accepts your existing Claude Code or Codex subscription and whether your team also needs a built-in agent.
• Infrastructure control: compare Ona's AWS Core and enterprise VPC model with a self-hosted system or a vendor-hosted environment.
• Audience and cost: count developers who need environments separately from teammates who only need to open a finished tool, then compare OCU, environment and per-user pricing.

The shortlist

CloudCLI

CloudCLI is the closest small-team alternative for continuous cloud development with an existing coding agent. It supports Claude Code, Cursor, Codex and Gemini CLI through subscriptions or keys, and offers browser, mobile, VS Code and SSH access. It does not include a database or finished-artifact publishing layer.

• Fit: developers who need an agent terminal to stay active and reachable from multiple devices.
• Price model: paid monthly environment tiers with a short Hobby trial and charges for additional Growth environments.
• Wins on: straightforward bring-your-own-agent remote environments and a self-hostable codebase.

Coder

Coder fits larger organizations that want all development workspaces on their own infrastructure. Its Community tier provides unlimited self-hosted workspaces, while paid Premium tiers use annual per-user pricing that is not publicly listed. Claude Code, Codex, Cursor and other agents can run inside the environments.

• Fit: platform teams that prioritize security policy, infrastructure ownership and standardized remote workspaces.
• Price model: free Community software plus paid annual per-user enterprise tiers with unpublished prices.
• Wins on: self-hosted control of the development environment fleet.

Grain

Grain solves the downstream publishing job. Your coding agent writes a page, app, report or job, and Grain gives it a workspace with a URL, optional Postgres, logins, schedules and comments. It does not supply a general development environment or its own agent, so it may complement Ona rather than replace it.

• Fit: teams whose main gap is sharing finished agent-built work with people who do not need a cloud development seat.
• Price model: free unlimited published artifacts, ten sleeping sandboxes and one always-on workspace; per-user Pro adds capacity, team spaces and custom domains.
• Wins on: a durable artifact and feedback surface independent of agent selection.

Conductor

Conductor is an alternative when the desired workflow is local and Mac-based. It runs multiple bring-your-own coding agents in parallel workspaces. Paid plans add multiplayer and team collaboration, while cloud workspaces use Vercel sandboxes rather than Ona's general AWS environment model.

• Fit: Mac developers coordinating several local or cloud agent tasks and reviewing their diffs.
• Price model: free, monthly Pro, per-user Teams and custom Enterprise tiers.
• Wins on: parallel agent orchestration close to the developer's local work.

Ona

Staying with Ona avoids a speculative migration. Core includes AWS-based environments, project sharing and up to one hundred team members without extra member charges. Ona also offers its own agents while allowing Claude Code or an existing Codex subscription, which is broader than a purely bundled-agent model.

• Fit: teams that want managed cloud environments, role-based access and a hybrid of Ona agents and existing agent subscriptions.
• Price model: paid monthly Core based on included and add-on OCUs, plus custom Enterprise arrangements.
• Wins on: combining managed environments, large team membership and hybrid agent access.

Where Grain fits, and where it does not

Grain fits if the acquisition prompts you to decouple finished output from the environment where it was made. A developer can work in Ona, Coder, CloudCLI or locally, then publish the resulting files to Grain for viewers and commenters. Grain does not replace Ona's cloud development environment, OCU compute model, project access or own agents. Choose Ona when you need a managed environment and value its hybrid agent setup. Choose Coder for self-hosted enterprise control, CloudCLI for lightweight continuous remote access, or Conductor for local parallel agents. Choose Grain only when the durable artifact and its audience are the missing layer.

Migration path

1. Before moving, export or clone each repository and record environment definitions, secrets, OCU-dependent jobs and role assignments. The acquisition announcement alone is not a reason to rush this inventory.
2. Choose a replacement for each layer. Put active development into CloudCLI, Coder, Conductor or another environment; do not expect a publishing hub to recreate a developer workspace.
3. For finished output in Grain, open the project folder and run grain init. Let the chosen CLI agent adapt application data to Postgres where needed.
4. Run grain push, grain checkpoint -m "move from ona" and the required share mode. Verify the URL with a user who has the intended permissions.
5. Run old and new paths together until development, data, scheduled work and audience access are proven. Ona agent history, OCU balances, environment configuration and project roles do not automatically move.
