Introducing: Mainplane🛫 A new open-source AI agent I built from scratch in Go

Local agents die with your laptop. Cloud agents can't reach your work. Mainplane lives on your server and drives all your computers

> Your old computers → always-on AI shed
> Shared file server for all computers
> Use a Claude/ChatGPT plan on regular usage limits
> Browser + computer use on Mac, Windows and Linux

One line to install

100% open source, MIT ↓

I cannot believe the difference
adding “agents are incredibly intelligent, make all tasks extremely ambitious” had on my Astra swarm

I realize most people haven't seen how OpenAI models write in swarms when they think nobody is looking

Complete neuralese

Everything in this video was made by Mainplane

Here is how:

1. Opus 5.5 wrote a script: what to say, what to open, what to type
2. My Mainplane got linked to a MacBook, a Windows laptop, a Linux box, my Mac mini and my 5090 PC
3. It drove each computer itself: opened the apps and typed with native computer use
4. It recorded each computer's screens directly and with timestamps
5. Then it stitched together the videos to transfer focus between the machines

No human processing needed. What you see is what you get

Requirement that computer use be done in background and with shell not allowed is arbitrary

It’s so much more powerful to allow full computer access, including shell, on agents own computer

1/ Today we're launching Cua Driver Bench, together with Scale AI's AgentEnv.

Can an agent do a desktop task in the background while you keep working undisturbed? On macOS, Cua Driver fully passed 58%, Codex computer use 33%, Vercel's agent-desktop 20%, browser-use 3%.
