Zro CLI is an MIT-licensed command-line tool that runs your existing agent harnesses — Claude Code, Codex, OpenCode, Hermes — against open models, so you can point the coding harness you already use at an open-weight backend. It is self-hostable and early: 2 stars, near-zero traction, created 2026-07-22, last pushed 2026-09-24.
Teams standardize on a coding harness — Claude Code, Codex, OpenCode, Hermes — but that usually locks the model behind it too. Zro CLI's angle is model portability: keep the harness your team already knows and point it at open models from the command line, so the backend becomes a choice rather than a fixed dependency. For a team weighing cost, data-control, or self-hosted inference, being able to swap the model without swapping the workflow is the useful lever. The honest read: at 2 stars this is early and lightly proven, and the exact breadth of harness and model support is the project's own claim — so test the specific harness/model combination you care about before you rely on it in a real workflow.
