OpenAI employees have recently hinted at the potential development of a native Codex app for iOS, igniting interest among users. In the meantime, developers and tech enthusiasts have found a useful alternative in an indie app called Remodex, crafted by Italian developer Emanuele Di Pietro. This utility allows users to control their existing Codex setups remotely from their iPhones, providing a user interface reminiscent of the official Codex app for Mac.
Remodex functions as a remote for the Codex CLI installed on a macOS computer. It is not a hacky workaround but is instead powered by OpenAI’s official and open-source Codex App Server. Users can easily access their Codex projects and chats as long as they have the Codex CLI installed on their Mac, which can be connected via a secure network service like Tailscale. After installing a small server bridge on the Mac, users simply scan a QR code from their iPhone to initiate the connection, granting them access to resume chats or start new ones.
Among the features, Remodex allows users to utilize the latest GPT-5.5 model, enable Fast mode with speed control, and upload files or images. Users can even dictate text, which is transcribed by Codex running on their Mac. The seamless connection facilitated by Tailscale means that users can access their Codex workspace from virtually anywhere, negating the need to be physically near their Mac.
While the app has its strengths, such as the ability to connect to a local Codex instance with added functionalities beyond what is available in the Codex cloud integration, it is not without flaws. Some users have reported issues, including responses loading out of order or the need to force-quit the app to resolve glitches. Nonetheless, the overall experience has proven valuable for users like myself, who appreciate the ability to leverage additional tools available on their Mac.
In discussing Remodex, Di Pietro expressed his admiration for OpenAI’s approach to open-source projects and how it empowers developers to create their own solutions. “I used the Codex App Server to build the app,” he said, emphasizing the collaborative spirit fostered by OpenAI’s support for third-party integrations. While aware of the competition that a potential native Codex app from OpenAI might present, Di Pietro remains optimistic about the future of indie developers in the space. “I took on this challenge knowing it was only a matter of time before OpenAI released its own version,” he remarked, pointing out that he has already managed to connect with many people at OpenAI.
Should OpenAI release its own native Codex app for iOS, there will still be opportunities for developers like Di Pietro to innovate. Features not included in the official app, such as broader integration with other coding agents or enhanced user options, could allow indie developers to carve out their own niche. Currently, Remodex is free to download on the App Store, with a subscription model available for $3.99/month or $29.99/year to unlock all features. However, it does not yet support an iPad version, nor does it display the automations and plugins installed in Codex.
Di Pietro is also working on a new project known as DP Code, which is a fork of the open-source T3 Code app. He envisions potential integration with Remodex to expand its capabilities, possibly accommodating additional providers in the future. “That would mean expanding Remodex to include more providers, such as Claude, OpenCode, and Cursor,” he said, although he acknowledged that such plans are still uncertain.
The narrative of an indie developer challenging established norms in tech is compelling, and Remodex exemplifies this spirit of innovation. For now, as I continue to work within Remodex, I find it fulfills many of my needs, replacing other coding agents on my Mac. The app’s sleek design, which embraces the aesthetics of iOS 26, enhances the user experience, distinguishing it from traditional command-line utilities.
Until OpenAI rolls out an official Codex app for iOS, Remodex will play an essential role in my workflow, offering a glimpse into the potential of third-party development in an increasingly competitive landscape.
Remodex is currently available for free on the App Store.
