Everything you might ask about OpenEng.
What it is, whether it is free, where your code goes, which platforms it runs on, and how to get started.
What is OpenEng?
OpenEng is a suite of four professional developer apps — Terminal, Kubernetes, Git, and Board — that run in your browser but execute on a small engine you run on your own machine. The browser is a thin UI; all the real work happens locally on your hardware.
Is OpenEng free?
Yes. Every app and every feature is free to use. There are no tiers, subscriptions, or paywalls — you just install an engine and open the app.
Where does my code go? Is it private?
Your code, repositories, clusters, terminal output, and boards never leave your machine — all work runs locally. The browser app drives a local engine over a sealed channel relayed by OpenEng’s broker; every frame is sealed end-to-end, so the broker only ever passes through ciphertext it can’t read.
Which operating systems does OpenEng support?
The engine runs on macOS (Apple silicon and Intel), Linux (x86-64 and ARM64), and Windows (x86-64). The apps themselves open in any modern browser.
How do I install OpenEng?
Install the small native engine for the app you want with a one-line script, then open the app in your browser and sign in once. The app shows you a one-time command to start the engine (it carries your sign-in token) — copy it, run it, and the page connects automatically.
Do I need to sign in?
Yes — you sign in once with Google inside the app to pair your browser with your local engine. After that, your browser reaches your engine through OpenEng’s broker, which relays only sealed frames it can’t read.
Is OpenEng open source?
No, OpenEng is not open source. It is free to use and private by architecture — your data stays on your hardware — but the source code is not publicly available.
