Update #6

A little more color for your Harness.

DeeCreatorOctober 9, 2026

We've been playing around with colors and thought it was time to give Harness a few new looks. From subtler, darker tones to something bolder, more ways to make it feel like your own. Which color is your favorite?

Update #5

Bring your buddy to Harness.

DeeCreatorOctober 5, 2026

Your coding setup is personal — your Harness should be too. Today we’re shipping custom characters. Give your desk companion a new look, make it yours. Can’t wait to see what you come up with.

Update #4

Harness goes beyond code. Build whatever.

DeeCreatorSeptember 29, 2026

We started Harness with coding agents — why stop there? Now your agents get real tools: Blender, CircuitJS, MuJoCo, Godot, Strudel. Each craft gets its own harness with a live viewer to see and steer as you go. All open source.

Update #3

All your agents just got a 🎃 for Halloween.

DeeCreatorSeptember 28, 2026

We released a limited-edition Harness. A device that shows what Claude Code and Codex are doing and pings you when they're done. What color should we do next?

Update #2

You guys love Harness. So we decided to open source it.

DeeCreatorSeptember 18, 2026

Our repo includes everything: desktop app, mobile app, firmware, schematic, and 3D industrial design. Time to build your own harness.

Update #1

Harness now runs Command Code, made for the team who built it.

DeeCreatorAugust 14, 2026

The Command Code team wanted to see their agent on Harness. So we made them one. Yours can be customized too.

The way we use computers changed. The hardware didn't.

Mouse and keyboard held for forty years. Then agents arrived. Typing became the slow way to work. Tracking which agent is doing what, on which machine, became a full-time job — Harness is the device for that. Skip typing, just say one sentence. The work goes to the right agent, on whichever computer or server it lives on. It drives every agent you already use, and the newest ones.

All your machines, one device.

Your laptop, the desktop under your desk, a box in the cloud - Harness shows every agent running on all of them, right by your keyboard. See which one's running, which one's stuck, which one finished an hour ago.

Swipe through every agent.

Claude Code, Codex, OpenCode, Cursor, and a dozen more. Swipe to see which one's working, which one's done, which one needs you — "Review PR #212" needs your answer while "Changelog" still has 2 minutes left. Tap and say the next task.

Close the lid. Agents keep going.

Close the laptop, quit the app, restart - your agents keep working on every machine. Harness tells you the moment one's done, and shows you what ran while you were gone.

One Tap. Say the task. Step away.

Tap on the face and speak: "watch the deploy pipeline and flag anything red" or "keep running the test suite until it passes." Harness dispatches the task to the agent already running on your laptop, your server, or the cloud. Line up several tasks — Harness pings you when work finishes, or when something needs your call.

Every task. Every agent. One glance.

The round display carries three things and nothing else: what is running and for how long, down to the second; the finished work, streamed on the moment it returns; and what your harness has spent today, down to the cent and readable across the room. No chat window, no feed, no personality — Harness doesn't talk back, it gets back to you, with one quiet tone when work returns. Voice in, work out, quiet in between.

A circle. A stand. Nothing else.

Harness is a single matte-black disc — one material, one colour, no buttons to find and no menus to learn. The whole face is the tap surface. The stand ships in the box and is part of the product: a low, weighted cradle that holds Harness upright at the base of your monitor, facing you like an instrument. USB-C on the bottom edge, a loop up top for the days the desk comes with you.

Your agents. Your machines. Your Harness.

Claude Code, Codex, Cursor, OpenCode, Pi, Hermes, Command Code, Devin, Muse, Amp, Kilo, Grok, Antigravity, Copilot, and more — the agents you already run, on the machines you already own. Nothing to migrate, nothing to rewrite. When they finish a task, hit a loop, or complete a goal, Harness catches the signal and brings it back to your desk. One face for every agent. Speak into it. See the work on it.

End-to-end encryption.

The agent runs where it already runs — your laptop, your server. Files, diffs, commits, logs, the repo itself: all of it stays there. The only thing that comes back to Harness is what got done, and what needs you to confirm. We don't keep a copy of the work either.
