DeepSeek Harness or Hermes — you only need one, and I'll show you which.
One of them just pulled 113,000 GitHub stars in two days.
The other has 226,000 and six months of head start.
Both are free. Both are open source.
By the end you'll know exactly which one should be running your business.
And there's a third answer almost nobody talks about — stay to the end for that one.
You've got two agents open.
Both free. Both open source. Both promising to run your whole business.
So you pick one.
Three weeks later you find out the other one was better at the exact thing you needed.
You've already wired your workflows into the wrong one.
That's the real cost — not the money, the rebuild.
That's the plan — but only if you know what each one is actually best at first.
This whole page is that, tested on my own machine.
The model got the attention. The harness is the bigger story.
It reads your files, runs commands, changes code and searches the web — on your own machine.
What you're watching: a real task on my machine — I ask it to list the workspace and write a summary. Watch the steps appear one at a time: glob, read, read, read, think, write. It finished in 5 steps and produced notes.md. Real session, played back at ~2× speed.
The model, the tools, the memory, the search, the subagents, even the loop that makes it think — all plugins.
What you're watching: I asked the harness to count its own plugins. The app you click on is 129. The same agent with no screen is 81. The 48 that vanish are the interface itself — so even the window is a plugin you can unplug. Real commands, real output from my machine.
Most agents arrive welded shut. This one arrives as parts, with instructions.
And when you pull a plugin out, everything it added rolls back with it. No leftover mess, no broken pieces hiding in your setup.
The plugin system underneath is called Cordis — and it's been running a public chatbot project called Koishi for years.
From Nous Research, launched 25 February 2026 — and it talks to you everywhere you already are.
Most agents wake up every morning with amnesia. This one doesn't.
What you're watching: my own Hermes profile. Three memory files, 213 skill files it has written for itself, and six jobs that run on a schedule while I'm asleep. That's the part people love, and it's real.
Run both for a few weeks and three real differences show up. The third one decides it.
One dashboard where Hermes, DeepSeek Harness, Claude, OpenClaw and free Claude Code all plug in — sharing one memory of your business.
Nothing is hidden. Every task shows you exactly what the agent did, and you can replay all of it.
What you're watching: the trajectory panel on the run from earlier. Every prompt, every context block, every tool call and its result — scrollable, searchable, in order. If something goes wrong, you can see exactly where.
Hermes is powerful, but fiddlier. Its own commit log tells that story better than I can.
What you're watching: I read Hermes' own commit history on my machine. Six session and state fixes. Five Windows fixes. Sixty-three of the last hundred and twenty commits are fixes. To be fair to Nous Research, shipping fixes fast is a good sign — but you feel those bugs in the meantime.
I run Hermes every day and it does jobs nothing else does.
These are its own release notes, not my opinion.
It's a developer preview, and DeepSeek says so themselves — things will move around as it matures.
Composio benchmarked eight harnesses on long-running work tasks — same model in every one, so only the harness changed.
DeepSeek Harness is too new to have been in that test, so watch for the next round. One test doing the rounds this week: someone asked it to build a full interactive teaching website from scratch — it finished in about 20 minutes, with working animations, accurate diagrams, and summary and quiz sections nobody asked for.
Ask for a landing page, a research report, a fix on your site — same model, different harness, different quality.
The old argument was "Hermes has scheduled tasks, Harness can't run while you sleep." That argument is already dead.
The deeper point: any feature you like in Hermes can be built into the Harness. The plugin system is the feature. Voice, messaging, memory bridges — they're all on the community list already.
Hermes still does things the Harness doesn't do out of the box — and six months of work went into exactly that.
Same install, four different agents — and Creator mode lets you build a fifth.
What you're watching: the real mode switcher on my machine. Standard is the full agent. Code mode chains many tool calls into one program. Minimal strips it to two tools. Creator mode lets you inspect the running system and build your own presets.
Hermes watches and pings my phone. The Harness does the heavy building. Each in the lane it's good at.
What you're watching: my own Agent OS. Hermes sits in the sidebar with every other engine, and the DeepSeek tab has a Coder / Harness toggle. Same dashboard, same memory of my business, both agents one click apart.
Wrong: "I'm not technical — plugins and configs aren't for me."
Right: One command opens a page in your browser. You type what you want in plain English and watch it work. It's a reading skill now, not a coding skill.
Wrong: "This changes every week — I'll wait until it settles."
Right: The changing is the reason to start now. The people who started in February are six months ahead, and the dust isn't going to settle. The gap just grows.
Wrong: "I don't have time to learn another tool."
Right: That's backwards, and I say it kindly. These agents exist to give time back. The real cost isn't learning the tool — it's the hours you keep spending on work an agent could already be doing.

Hundreds of thousands of people are setting up AI agents to do real work — this month.
These tools are free. The models behind them keep getting cheaper or free outright. The only thing separating the people getting results from the people watching videos about it: the first group set something up and let it run.
This page tells you which agent to pick. The Agent Operating System is the part that saves you the months of wiring — your Harness, your Hermes, your Claude, your OpenClaw and your free Claude Code in one dashboard, with your workflows built in.
I've added tools for videos, SEO agents, AI avatars, the lot. Since Harness launched this week, the daily tutorials are covering it right now — how to set it up, which plugins are worth adding, how to run it next to Hermes so each one covers the other's gaps.
Readers bookmark this page and pick the wrong engine anyway. Operators join, install it this week, and have both agents working by Friday.
