Workflows
Codex Web (ChatGPT Plus only)
How it works
- Codex runs in the browser, but executes commands in a managed sandbox on OpenAI’s side.
- You can mount a GitHub repo, edit files, run builds, deploy — all without touching your local machine.
- Approvals are web-based: Codex will ask before writing files, committing, or pushing.


Pros / Cons
- Zero setup: works anywhere you have a browser.
- No Docker Desktop, no WSL, no local dependencies.
- Safer than YOLO mode: actions require explicit web approvals.
- Slower feedback loop: commands run remotely, not on your machine.
- Limited integrations: less control over caching, networking, local tooling.
- Still a security risk — you’re pasting commands into a remote shell.
When to use
Codex in Visual Studio CLI (Open Source possible)
Breaking down the command
codex→ the CLI client.
-ask-for-approval never→ disables approval prompts. Codex won’t stop to ask before editing or running; it just does it. (⚠️ In my experience, this didn’t work)
-sandbox workspace-write→ gives Codex write access to your project workspace. Everything else is read-only.
config.toml and your version of codex, you might also need to approve commands it runs.Pros / Cons
- Seamless: Codex runs right where you code, in the same terminal.
- Fast loop: no GUI clicks, no Docker overhead.
- Approvals disabled = maximum convenience. (if it works for you)
- Security risk: Codex can modify anything in your workspace.
- Less guardrails: if it makes a bad edit, it’s immediately in your repo.
- Easy to get lazy and stop reviewing changes.
- If you’re on a windows machine, you need WSL2
- If you’re using WSL2, it seems to not be able to run all linux commands, so it has to use other commands. This eats up a big part of it’s context.
Codex Full YOLO Docker CLI (Open Source possible)
- Have a Github repo + tech stack + hosting pipeline that automatically builds and deploys on push.
- Run Codex inside a container that mounts your project and Codex state.
- Approve once using(
/approvals), then give it full write access.
Running it directly
With Docker Compose
Pros / Cons
- Runs inside Linux: low context overhead, feels native.
- Fast startup, no manual approvals needed.
- Convenient for experimentation or continuous development.
- Security risk: if Codex executes malicious code, it has broad access.
- Encourages laziness: skipping reviews means skipping safeguards.
Use cases
Use codex for an ai powered changelog writer
name: Update changelog via Codex run: | npm install -g @openai/codex export OPENAI_API_KEY="${{ secrets.OPENAI_KEY }}" codex exec --full-auto "update CHANGELOG for next release"
