Private, fast inference for coding agents

Open-weight models. Zero data retention. Zero training. Long-context, multi-region speed.

zro.moonmath.ai · Pricing · Integrations

zro is the CLI that connects your coding agent to the Zro inference endpoint. It launches the agent of your choice with isolated, Zro-owned configuration — so it never touches your everyday agent setup, credentials, or session history.

No training on your prompts or completions. Zero request retention. Runs on privacy-forward, multi-region infrastructure. Optimized for the long-context, tool-heavy workloads coding agents depend on.

npm install --global @moonmath-ai/zro
zro login
zro claude

Run zro models for the models available to your key, or see zro.moonmath.ai/pricing. Region availability is shown when you create an API key.

Quick start

zro login                 # website or API key login
zro claude                # open Claude Code on the default model
zro codex -m <model>      # pick a model for this session
zro models                # browse the model catalog
zro status                # connection, installed tools, last session, usage

zro <tool> --install installs a missing agent and opens it in one step.

Installation

• Requirements: Node.js 22 or later on macOS, Linux, or Windows.
• Install: npm install --global @moonmath-ai/zro (also pnpm add --global @moonmath-ai/zro).
• Upgrade: zro install --upgrade (upgrade zro); zro install <tool> --upgrade or zro install [email protected] / zro install claude --version 2.1.105 for an agent.
• Agent-assisted setup: SETUP_PROMPT.md has copy-paste prompts for end-user installs and local development checkouts.

Authentication

Sign in once, then launch any supported agent:

zro login                    # website or API key login
zro login --manual           # enter an API key directly
zro login --no-browser       # print an approval URL (e.g. remote box)
zro logout                   # remove the stored login

• Website login creates a revocable API key after approval, encrypted to an ephemeral CLI-held public key. Set ZRO_DEVICE_NAME to label the device.
• ZRO_API_KEY takes precedence over the stored key at ~/.config/zro/credentials.json; Codex App keeps its own copy under ~/.config/zro/codex-app/.env; zro logout removes both.
• The credential is verified against the inference API before any launch.

Supported coding agents

| Agent | Install | Notes | | --- | --- | --- | | Claude Code | zro install claude | Anthropic's coding agent | | Codex CLI | zro install codex | OpenAI's terminal agent | | Codex App | zro install codex-app | OpenAI's desktop app | | Kilo Code | zro install kilo | Kilo's terminal coding agent | | Oh My Pi | zro install omp | Power-user terminal agent | | OpenCode | zro install opencode | Open-source coding agent | | Grok Build | zro install grok | xAI's coding agent | | Hermes | zro install hermes | Nous Research's agent | | OpenClaw | zro install openclaw | Personal AI assistant | | Pi | zro install pi | Minimal coding agent | | Prime Agent | zro install prime | Prime Intellect's self-improving RLM agent |

Each adapter launches the installed tool as a child process with isolated, Zro-owned configuration. Session files are temporary; Codex App uses a persistent Zro-owned home. Pass native tool arguments after -- (for example zro oc -- --help). The last tool/model pair is remembered and reopened with zro again.

Usage

zro                         # interactive agent picker
zro claude                  # open directly on the default model
zro codex -m <model>        # choose a model for this session
zro omp -m <model>          # launch Oh My Pi through Zro
zro kilo -m <model>         # launch Kilo Code through Zro
zro oc -- --help            # short aliases + native tool arguments
zro again                   # reopen the last tool/model pair
zro models                  # readable model catalog
zro install [email protected]  # pin an agent version
zro feedback                # send feedback to the Zro team
zro claude --dry-run        # secret-safe session preview
zro codex --json            # machine-readable preview

Pricing

Plans are spend-based with expected usage, so actual totals vary by model mix, prompt shape, output length, and cache reads. See the live pricing page.

| Plan | Per month | Yearly | Expected usage | | --- | --- | --- | --- | | Pro | $20 | $16/mo | ~1B tokens | | Max | $60 | $48/mo | ~5B tokens |

• Usage packs are available with or without a subscription and expire after 90 days.
• Monthly spend resets on the same calendar cadence for monthly and yearly subscribers.
• There are no prorated refunds on cancellation; access stays active to the end of the period.

Safety

• Normal agent configs are never edited.
• Temporary session files live under ~/.cache/zro/sessions and are removed when the agent exits.
• Kilo Code and Oh My Pi run with a temporary home and XDG profile; only sanitized preferences and safe assets are copied in. Provider credentials, MCP definitions, sessions, databases, dependency trees, and secret files stay outside the profile.
• Kilo and Oh My Pi telemetry, OTLP export, automatic updates, sharing, and remote control are disabled; model and MCP requests still go to the configured Zro endpoints.
• API keys are masked in human and JSON previews. --dry-run writes nothing and starts nothing.
• macOS, Linux, and Windows are supported.
