Update #6

A little more color for your Harness.

DeeCreatorOctober 9, 2026

We've been playing around with colors, and we thought it was time to give Harness a few new looks.

From subtle, darker tones to something a little bolder, you now have more ways to make Harness feel like your own.

Same little companion, just with a fresh coat of personality. Which color is your favorite?

Update #5

Bring your buddy to Harness.

DeeCreatorOctober 5, 2026

Your coding setup is personal. We think your Harness should be too.

Today, we're shipping custom characters for the Harness device. Give your little desk companion a new look and make it feel more like yours.

We've always wanted Harness to be more than just another tool sitting on your desk. Now you can give it a little personality, too.

Can't wait to see what characters you come up with.

Update #4

Harness goes beyond code. Build whatever you're curious about.

DeeCreatorSeptember 29, 2026

We started Harness with coding agents. But why stop at code?

Now you can give your agents real tools to work with. Design 3D models in Blender, build circuits in CircuitJS, simulate robots in MuJoCo, make games with Godogen, or create music in Strudel. Each craft gets its own harness, with the tools and a live viewer so you can see what's happening and steer as you go.

It's all open source. Start with code, then see where your curiosity takes you.

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.

Bring your own agent.

Every agent Harness runs today joined through an open protocol. Yours can too. Ship a CLI command or deploy an HTTP endpoint — both open source on GitHub.

Set a Loop. It runs on schedule.

Say the schedule once — "every 9am, check the overnight deploy" — and it runs. Every day, every hour, every Monday morning, whatever you set. You get pinged only when there's something worth seeing. Not another Slack ping to ignore.

Set a Goal. It runs until done.

Not prompt, then prompt, then prompt. A Goal takes one instruction and runs it to done. Say "get all billing tests passing" once. The agent runs, fails, fixes, reruns, until every test passes. You get pinged when the goal is met.

Tap twice. Say the task. Step away.

Double-tap 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.
