Rein: Coding Agents, Anywhere

Rein — Remote control for your coding agents

Rein puts your AI coding agents in your pocket. Kick off work, watch it run, steer it when it drifts, and ship from your phone, using the agents and machines you already trust.

YOUR AGENTS, YOUR INFRASTRUCTURE

Rein doesn’t lock you into a house model or a rented sandbox. Point it at the agents you already run, like Claude Code or OpenCode, on your own hardware. Your keys, your environment, your repos.

START WORK THE SECOND IT HITS YOU

Ideas don’t wait for you to get back to your desk. Spin up an agent to chase a bug, draft a feature, or dig through an unfamiliar part of the codebase the moment you think of it. Long-running jobs keep going whether the app is open or not. Check back when it matters.

STAY IN THE LOOP

See live output as it happens. When an agent stalls, guesses wrong, or asks a question, you’re there to answer. No waiting on a finished run to find out it went sideways an hour ago. Redirect mid-task, approve the risky step, or kill it and start over.

TALK INSTEAD OF TYPE

Describe the fix out loud while you’re walking, away from your keyboard, or half-awake. Rein turns loose thinking into real instructions your agent can act on, so nothing gets lost between the idea and the commit.

REVIEW AND SHIP WITHOUT A LAPTOP

Read diffs built for a small screen, move through files and commits, and merge when it’s ready. From quick fixes to real features, close the loop from the same place you opened it.

• Connect to the agents you already run
• Keep your keys, environment, and repos yours
• Launch and monitor work from your phone
• Step in live: redirect, approve, or stop
• Voice in, code out
• Review diffs and merge on mobile

Take the reins from anywhere.
