Neox open source
A terminal AI coding agent (CLI), the agent runtime under it, an SDK and an agent operating system, all open source under Apache-2.0. Bring your own model key and run it locally, no account needed.
OpenNeox
An open-source AI coding agent for the terminal: it reads code, runs commands and edits files with the model you choose. The Neox client runs on the same runtime.

OpenNeoxOS
A self-hosted operating system for AI agents: every agent is a real OS process with kernel-enforced boundaries, an append-only event ledger, and git-worktree collaboration.
Processes die; the conversation doesn’t. An append-only ledger rebuilds state at any point, so a restarted agent picks up where it stopped.
On Linux, declared capabilities become landlock, network-namespace and cgroup2 rules that child processes inherit. On macOS it degrades to Seatbelt (writes only), and the self-check reports which layer is in effect.
Several agents on one project each get a git worktree branch; sync, merge, handoff and rollback are plain git.
Crossing a boundary asks a human instead of crashing; once approved the process relaunches with the wider scope and the conversation continues. Credentials never enter a confined process.
