Codex Cloud

Devin, Cursor Cloud, and Codex Cloud are cloud Agent platforms, aimed at any repository and any tech stack, and can even handle backend projects.

In Codex Cloud, each chat thread corresponds to an independent Docker container.

When selecting tools, priority should be given to those that match the existing code hosting location and subscription plan, rather than simply comparing which is more capable.

When creating a Codex Cloud environment, Codex automatically inspects the repository, identifies dependencies, and completes the environment configuration preparation.

Codex Cloud adds OIDC support to facilitate access to cloud resources via OIDC.

Codex Cloud environments can be connected via Tailscale as a VPN to access internal resources within a private network.

Codex Cloud writes a startup skill to teach the Agent how to use the environment and generates a startup script.

Currently, Dot does not consume ChatGPT usage quota and is nearly unlimited, unless it delegates tasks to local Codex or Codex Cloud.

Tasks can be dispatched to the user's own computer, Codex Cloud, or Dot's own cloud computer for execution.

In the Codex Cloud demo, the AI assistant Dot can be instructed to create a PR, run tests, and flag content that requires human approval.

Codex Cloud supports cross-device handoff, allowing developers to initiate a task on a computer and continue adding instructions from a phone without interrupting execution.

The content of this article is based on OpenAI's official demo; the stability, configuration complexity, and cost performance of the cloud environment still need further validation in real projects.

Codex Cloud now supports running on three platforms—local machine, mobile, and cloud—and provides reusable development environments.

Once launched, Codex Cloud tasks run entirely independently of the local device, allowing users to close their laptop or switch to another device while tasks continue executing in the background.

Users can resume the same task from any device, and can even append instructions to a running task from a phone without interrupting its current execution.

Codex Cloud can use natural language instructions to have the assistant automatically create PRs, check results, run tests, and flag areas requiring human approval.

After a Codex Cloud task is complete, a Pull Request can be created, or an entirely new code review process can be followed.

Once configured, Codex Cloud generates a named environment, which is essentially a snapshot; multiple independent tasks can be launched in parallel from the same snapshot for team reuse.

When sharing a shared environment, Codex Cloud allows team members to override default settings with their own secrets, either by entering them inline or by calling them from a personal vault.

Codex Cloud's configuration capabilities cover advanced scenarios including network settings, environment variables, and secrets management.
