The fix happens outside the chat

The diff it wrote, the file it broke, the test that failed, the app it built. One tap from the conversation.

Two files changed, five lines. The diff is one tap away.

Every agent, one desktop cockpit

Your live sessions, tiled. One is about to need you.

You find out the moment an agent needs you

It runs on your dev machine. When an agent stalls, your phone buzzes instead of you finding out in the morning.

Why I built this

I'm a robotics software engineer, and DevReins exists because of one recurring, annoying problem.

Nearly all of my side-project code is written by agents that run while I'm at work or asleep. An agent stuck on a permission prompt at 11pm is a solved problem — the vendors' own apps can buzz you for that. But I run Claude, Codex, and Gemini at once, and half the time the right answer isn't "approve," it's "let me look" — at the diff, the files, the app it just built. So I made one queue for every agent, with the machine itself one tap past the chat. I've run it every day since.

Common questions

Which AI coding agents does DevReins work with?

DevReins tracks Claude Code, OpenAI Codex, and Gemini CLI natively. Cursor CLI, Aider, and other terminal agents can be driven through live session panes, so you are not locked to one model vendor. Guides: use Claude Code from your phone and use Gemini CLI from your phone.

How is DevReins different from the Claude or ChatGPT app?

Those apps are first-party remotes: each is built around prompting, approving, and reviewing its own vendor's agent, and each does that well. DevReins covers every agent on your machine in one queue, Claude Code, Codex, and Gemini included, and adds controls no agent sits in the middle of: a real terminal, a file browser, repo-wide git, a localhost preview, and the desktop. Many people run DevReins alongside the first-party apps.

What does DevReins send through its relay?

DevReins runs machine actions locally. Its relay forwards encrypted session payloads and is not issued the session keys. Your coding-agent provider may still receive prompts, source excerpts, and tool results under that provider's settings.

Do I need to set up a tunnel, VPN, or port forwarding?

No. Your machine connects outbound to the relay, so it works behind NAT and firewalls with zero network configuration. Install the app, run the server, log in, and pick your machine.

Is DevReins a remote desktop app?

No. Remote desktop hands you a tiny screen and a mouse. DevReins is built around your agents: it tells you the moment one stalls or needs approval, lands you on the exact blocking request, and gives you files, git, and a terminal to act with.

Does it work on iPhone?

Yes. Log in from Safari and add DevReins to your home screen; it runs as a full-screen web app. A native iOS app is planned.

How much does DevReins cost?

DevReins is free during early access, including managed relay access. A planned Pro tier will charge for hosted convenience after early access; billing is not live and the final feature set may change.
