OpenEng Chat
Beta nowA coding agent that never leaves your machine.
A local coding and integration agent. The browser is a thin client; model inference, repository indexing, file edits, and every conversation happen inside a sealed engine on your own hardware. No prompt, model file, or line of your code leaves the device.
In the app
Install the engine
Open the app & sign in
Chat in your browserThe app gives you a one-time command to start the engine — copy & run it.
Chat features
Everything you reach for, built in.
Models on your hardware
Run open-weight models locally through llama.cpp or mistral.rs, with downloads managed by the engine. Nothing is sent to a hosted inference API.
Repository-aware
A tree-sitter repo map lets the agent navigate and edit real codebases by structure rather than by guessing at file names.
Drives your other apps
Chat speaks to the sibling Terminal, Kubernetes, Git, and Data engines over the same sealed channel, so one conversation can run a command, inspect a cluster, and query a database.
Chat groups
Group conversations under a shared name and system prompt, and point each group at the connections it is allowed to touch.
MCP servers
Attach Model Context Protocol servers to give the agent extra tools, hosted by the engine alongside its built-in ones.
Private by construction
The UI reaches the engine over a per-frame sealed loopback channel. Conversations and model files are stored on your machine, never on an OpenEng server.
Runs on your machine, not our servers.
Chat is a thin browser client of a local engine you run yourself. Your shells and output stay on your hardware, and every frame that crosses the wire is sealed end-to-end.
