OpenAI Codex CLI
OpenAI's open-source terminal coding agent built in Rust.
Overview
Codex CLI is OpenAI's open-source coding agent that runs locally in the terminal, reading, editing and running code in a chosen directory. Built in Rust, it pairs with OpenAI's frontier models and supports parallel work via worktrees and cloud environments. It complements an IDE extension and a cloud-based Codex agent.

ASEAN Perspective
OpenAI Codex CLI in Southeast Asia
ASEAN-region availability and pricing notes coming soon. Drop the editorial team a note via /contact/ if you can supply local context (Singapore/Malaysia/Indonesia/Thailand/Vietnam).
Codex CLI is OpenAI's terminal-native answer to Claude Code, and it has scaled fast with millions of weekly users and strong agentic-coding benchmark results on the latest models. Being open source and Rust-built gives it speed and inspectability, though it depends on a paid OpenAI plan or API key for the underlying model.
The CLI itself is free and open source; model usage is freemium-to-paid. It is broadly available to ASEAN developers in English, subject to OpenAI's regional account availability.
