4.6$20/mo
Supports ArabicAPI
Overview
Codex is OpenAI's coding agent, powered by your ChatGPT account. The desktop app (macOS and Windows) acts as a command center for agentic coding: with built-in worktrees and cloud environments, multiple agents work in parallel across projects. It is also available as a CLI (npm i -g @openai/codex) and an IDE extension. Automations let it run in the background on issue triage, alert monitoring and CI/CD, Skills adapt it to your team's standards, and its code review reliably catches subtle bugs other tools miss. Pricing comes through ChatGPT plans — Plus at $20/month, Pro at $200/month for heavy parallel usage.
