What we know about Codex CLI
Codex CLI is the only agent in this set that confines itself in an OS-enforced sandbox on first run, with network access off and writes limited to the working directory.
“By default, the agent runs with network access turned off. Locally, Codex uses an OS-enforced sandbox that limits what it can touch (typically to the current workspace), plus an approval policy that controls when it must stop and ask you before acting.”
Point an agent at a repository you do not trust: in the default `workspace-write` mode Codex edits inside the working directory and must ask before touching anything outside it.
“Codex asks for approval to edit files outside the workspace or to run commands that require network access.”
Use a ChatGPT plan you already pay for instead of a second subscription, on Free, Go, Plus, Pro, Business, Edu or Enterprise.
“ChatGPT Work and Codex are included in your ChatGPT Free, Go, Plus, Pro, Business, Edu, or Enterprise plan”
Stop a team from disabling its own guard rails: an administrator can forbid `approval_policy = "never"` and `sandbox_mode = "danger-full-access"` in a requirements file.
“requirements.toml (for example, disallowing approval_policy = "never" or”
Subscription spend is unpredictable: the most-commented open issue, 630 comments since 2026-03-13, is that Codex burns the plan budget too fast, and a second reports the 5-hour budget gone in 2-3 prompts.
“Codex (gpt-5.5, Plus plan) — rate-limit cost per token jumped ~10-20x since June 16, draining the 5h budget in 2-3 prompts”
The agent cannot install a dependency until you edit the config, because the default sandbox keeps the network off.
“For the ChatGPT desktop app, Codex CLI, or IDE extension, the default workspace-write sandbox mode keeps network access turned off unless you enable it in your configuration:”
Windows is the weakest platform: an open issue with 106 comments reports the app freezing on Windows 11 Pro on hardware with resources to spare.
“Codex App frequently freezes/stutters on Windows 11 Pro despite sufficient system resources”
A developer who wants to run a local Ollama model should choose Crush or goose; Codex signs in with a ChatGPT account or an OpenAI API key.
“Run `codex` and select **Sign in with ChatGPT**. We recommend signing into your ChatGPT account to use Codex as part of your Plus, Pro, Business, Edu, or Enterprise plan.”

“*2+ users, billed annually. $25 per user per month when billed monthly.”
What this page does not answer
We have researched Codex CLI and we have not researched langchain-code. That means the judgments above answer for one tool and not for the other, and we publish no price for langchain-code because we have not read its pricing page. Nothing on this page about langchain-code is our opinion; there is not enough evidence yet for one.
Questions people ask

How we check this page
- Machine facts. Stars, contributors, the newest commit on the default branch, the licence GitHub reports and the latest stable release come from the GitHub API, and download counts from npm, PyPI, Homebrew and the VS Code Marketplace. Each value carries the day it was last confirmed, never the day this page was built. The line under each label is arithmetic on those two values.
- Judgments. Every claim about what a tool suits, what it is bad at and what it costs is quoted from a page we read, and that page is linked beside the claim. Where there is no link, we wrote no claim.
- Index status. Codex CLI carries claims we read, quoted and linked; langchain-code does not. So this page is offered to search engines.
