Route Codex and Claude Code through private open-model inference with Zro

Zro is a private inference endpoint built for coding agents that want open-weight models without wiring and operating their own serving stack. Its public docs position it as an OpenAI-compatible and Anthropic-compatible API for chat and messages, plus a CLI launcher that can start tools such as Codex CLI, Claude Code, OpenClaw, OpenCode, Hermes, and Pi with temporary provider configuration.

The practical angle is simple: if you want to test MiniMax M3 or GLM-5.2 inside a coding-agent workflow while keeping prompts away from default closed-model providers, Zro gives you a ready-made endpoint and launcher path. The integration docs show one-command setup with npm install -g @moonmath-ai/zro, zro login, and zro launch codex --model glm-5.2.

Pricing is not a free unlimited deal. Zro lists Pro at $20/month, Max at $60/month, separate $0.02 web searches, and usage packs for extra spend. Product Hunt also shows a launch offer: code PRODUCTHUNT for one month of Zro Pro free, limited to the first 100 users. Treat that as time-sensitive and verify availability before relying on it.

Caveats: the privacy and retention statements are vendor claims, not an independent audit in these sources. The site says current inference regions include Finland and France, so non-EU latency and data-residency needs should be checked before moving production workloads. The published token totals are estimates, not fixed allowances.
