When an agent stalls or asks to run something, your phone buzzes. Read what it wants, check the diff, approve it or tell it to do something else. It all runs on your own machine.
Free · Self-hosted · Cross-vendor: native Claude Code, Codex & Gemini — others via live panes
Built with DevReins
DevReins runs on your dev machine and talks to your phone over an encrypted connection. When an agent stalls or hits a permission prompt, your phone gets pinged instead of you finding out in the morning.
The agent below is simulated, but the flow and panels are the real product — agents, files, git, and a terminal on your machine. In a few seconds it will ask permission to run a command: one tap to approve, redirect, or stop, with full transcript context. Works natively with Claude Code, Codex, and Gemini — and drives Cursor, Aider, or any terminal agent through live session panes. Nothing to install.
Back at the keyboard, every agent tiles side by side in one window. Same loop — an agent below is about to need you.
I'm a robotics software engineer. Most of my side projects are written by agents that run while I'm doing something else, and DevReins exists because of one recurring, annoying problem.
I work full-time in robotics and run several products on the side — a civic-tech platform, a compliance tool, trading experiments. Nearly all of that code is written by agents that run while I'm at work or asleep. And the same thing kept happening: an agent would hit a permission prompt at 11pm, sit there waiting for a yes, and I'd find it the next morning. A whole night of progress lost to a question I could have answered in five seconds. So I built the thing that buzzes my phone, shows me exactly what the agent wants, and lets me answer it from bed, the gym, or the grocery line. I've been running it every day since.

There's no card to enter and nothing to buy yet. I want people using it hard and telling me what breaks. Paid tiers come later, and only for the hosted parts: the relay, push at scale, and the iOS app.
Claude Code, OpenAI Codex, Cursor CLI, Gemini CLI, and Aider — and any agent that runs in a terminal on your machine. DevReins watches the sessions themselves, so it isn't tied to one vendor.
No. DevReins is self-hosted: the server runs on your dev box and traffic to your phone is end-to-end encrypted. The relay only forwards ciphertext — it can't read your code, terminal output, or conversations.
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.
No. Remote desktop gives you a tiny screen and a mouse. DevReins is built around your agents: it notifies you the moment one stalls or needs approval and lands you on the exact blocking context — then gives you files, git, and a terminal to act.
Yes — log in from Safari and add DevReins to your home screen; it runs as a full-screen web app. A native iOS app ships with Pro.
Free during early access — no credit card, no trial timer. Pro ($19/mo: managed relay, push notifications, native iOS app) opens in v1.1.
One email when Pro opens. Maybe one before that if something big ships. That's it.
