Your engineering workbench,
in the browser.
Terminal, Kubernetes, Data, Git, and Board — five professional apps that run in your browser and drive a secure engine on your own machine. Nothing leaves your hardware.
One account · Free for all five apps · macOS, Linux & Windows
One suite
Five apps. One workbench.
Each app is a focused, professional tool — and they share one account, one secure local engine model, and a price of zero.
Terminal
The terminal that thinks in blocks.
A modern terminal where every command is a clean, copyable block. Organise sessions into named groups, drive real interactive shells, and run one command across many sessions at once — all executing locally on your machine.
- Block-based output
- Session groups & tabs
- Interactive shells
- Parallel execution
Kubernetes
A full Kubernetes console, one pane of glass.
Connect every cluster in your kubeconfig and work them like a native IDE — browse and edit any resource, stream logs, exec into pods, port-forward, manage Helm, and read live metrics. No kubectl required.
- Multi-cluster
- Live logs & exec
- Port-forward
- Helm & metrics
Data
Every database, one query workbench.
Connect to any database — SQL (PostgreSQL, MySQL, CockroachDB, SQLite), document (MongoDB), key-value (Redis), graph (Neo4j), object stores, and streaming (Apache Kafka) — browse the full object tree and run queries, all executing on your own machine. Cloud systems connect through least-privilege connectors that run in your own cloud.
- SQL · NoSQL · graph · streaming
- Adaptive object tree
- Query playground
- Cloud connectors
Git
A desktop-grade Git client in your browser.
Everything you normally drop to the CLI for — status, diffs, history, branches, push/pull, stash, tags, blame, and cross-history search — in one fast, repo-aware panel backed by libgit2.
- Status & inline diff
- Commit graph & history
- Branches & push/pull
- Blame & search
Board
An infinite canvas for system design.
A fast, infinite whiteboard tuned for architecture and system diagrams — shapes, smart connectors, sticky notes, freehand ink, and frames, with full undo and one-click export. Your boards persist locally.
- Infinite canvas
- Shapes & connectors
- Frames & sticky notes
- PNG / SVG export
How it works
The browser is the surface. Your machine is the engine.
Unlike SaaS dev tools, OpenEng never sends your code, clusters, or repos to a server. The UI lives in the browser; all the work happens on your hardware.
Install the engine
One checksum-verified line installs the small native engine for the app you want — no build step, no toolchain.
curl -fsSL https://openeng.ai/engine/terminal/install.sh | bashOpen the app & sign in
Sign in once in your browser. The app shows a one-time command to start your engine — your sign-in token baked in, single-use.
terminal.openeng.appPaste the command it gives you
Run the command the app shows — the engine starts on your machine and the page connects automatically, sealed end-to-end.
# paste the start command from the appConnection is sealed per frame with a fresh, unique key — end-to-end, even on your own machine. How we keep it private →
Why OpenEng
Serious tools that respect your machine.
Local-first & private
Your code, clusters, and repositories never leave your machine — every frame that reaches the browser is sealed end-to-end.
Free, every app
Every feature across Terminal, Kubernetes, Data, Git, and Board is free — no tiers, no subscriptions, nothing to unlock.
Native power, zero install UI
A real PTY, real libgit2, real kube clients — driven from a browser tab that’s always up to date.
Everywhere you work
The engine runs on macOS, Linux, and Windows; the apps open in any modern browser.
FAQ
Questions, answered.
The short version: four professional dev apps, free, running on your own machine.
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.
Every app. Every feature. Free.
All five OpenEng apps — Terminal, Kubernetes, Data, Git, and Board — are free to use. No tiers, no subscriptions, nothing to unlock. Just install an engine and open the app.
