2026 Codex Download Address Update: codexdown.cn Migrated to codexdown.cc (Including Client Downloads)

Recently, numerous users have raised questions about accessing Codex resources—why codexdown.cn is unavailable, if the download address has changed, and where to find the Codex client. Here’s the 2026 update to clarify these concerns.

The official Codex download site has officially migrated from codexdown.cn to codexdown.cc. The old domain is no longer in use, so users with codexdown.cn bookmarked should update their bookmarks promptly to avoid future access failures.

Domain changes are common operational adjustments, driven by reasons like unified domain planning, brand alignment, overseas access optimization, and long-term maintenance. For users, the key is to remember the new address: https://codexdown.cc/.

The new site provides a range of Codex resources: latest Codex Desktop clients for Windows and macOS, historical version archives (useful for developers testing different builds), installation tutorials, update logs, common problem solutions, and usage tips.

To download the Codex client, visit https://codexdown.cc/ and select the version matching your OS (Windows or macOS). Follow standard installation steps after downloading; old version users can upgrade to the latest release if needed.

We recommend updating all references to the old domain: browser bookmarks, developer tool bookmarks, tutorial links, and blog post references to ensure uninterrupted access.

Common FAQs:

• Q1: Can the old codexdown.cn still be accessed? No—switch to codexdown.cc for all access.
• Q2: Are downloads the latest version? The site syncs the newest versions and retains historical ones for specific needs.
• Q3: Supported systems? Windows and macOS.

In summary, for 2026 Codex client downloads, use the new site at https://codexdown.cc/. Future updates (new versions, installation guides, etc.) will be posted here.
