Opper CLI

The official Opper CLI, distributed as the npm package @opperai/cli. Source: github.com/opper-ai/cli. Requires Node.js ≥ 20.12.

The CLI is more than a thin wrapper over /v3/call. It also launches coding agents (Claude Code, OpenCode, Codex, Hermes, Pi) with their model traffic routed through Opper, installs bundled skills, and wires AI code editors to Opper.

Install

npm i -g @opperai/cli
opper --version
