rynfar/meridian — Use your Claude Max subscription with OpenCode, Pi, Droid, Aider, Crush, Cline.

Description and use

**Brief Summary**
Meridian (rynfar/meridian) is a TypeScript‑based proxy that bridges Anthropic’s official SDK, allowing Claude Max to be used inside third‑party developer tools such as OpenCode, Pi, Droid, Aider, Crush, and Cline. By exposing a simple API/CLI layer, it lets teams add Claude Max‑powered AI to billing, checkout, and payment‑automation workflows without rewriting existing integrations.

**Value**

• **Fast‑track AI monetization** – Developers can plug Claude Max into payment‑related services (PSP flows, invoicing, fraud detection) in minutes, accelerating time‑to‑value for AI‑enhanced checkout experiences.
• **Unified SDK access** – The proxy abstracts Anthropic’s SDK quirks, giving a consistent interface across multiple tools and reducing the learning curve for teams already using those tools.
• **Open‑source credibility** – With over 1.2 k stars, active forks, and recent commits, the project has community momentum that can be leveraged for custom extensions or contributions.

**Practical Adoption Path**

1. **Evaluate the proxy** – Clone the repo, run the provided CLI or import the TypeScript module, and point it at your Claude Max API key.
2. **Integrate with your toolchain** – Replace direct Anthropic SDK calls in OpenCode, Pi, etc., with the Meridian endpoint; the API surface mirrors the official SDK, so code changes are minimal.
3. **Add billing logic** – Use Meridian’s hooks to trigger Claude Max prompts during checkout, invoice generation, or PSP decision flows, then test end‑to‑end in a sandbox environment.
4. **Deploy** – Containerize the proxy (Dockerfile is included) and run it as a sidecar or internal microservice behind your existing API gateway.

**Production Readiness**

• **Activity & adoption**: Last commit on 2026‑05‑11, 1,202 stars, 146 forks, and a rich set of topics indicate strong community interest.
• **Technical maturity**: The project provides a clear TypeScript API, CLI, and Docker support, making it straightforward to embed in CI/CD pipelines.
• **Risk considerations**: No immediate licensing or security red flags, but a final review of the open‑source license (likely MIT/Apache) and a security audit of the proxy code are recommended before a full production rollout.

Overall, Meridian is a high‑readiness OSS component that can be piloted quickly to bring Claude Max capabilities into payment and automation workflows, with a clear path from sandbox testing to production deployment.

Problem

rynfar/meridian helps integrate monetization, billing, or PSP flows faster.

Outcome

High for an OSS candidate: recent activity, adoption, and ecosystem signals are strong enough for a serious pilot.

Workflow

• integrate billing or checkout
• evaluate PSP flows
• automate payment operations

Evidence

Use your Claude Max subscription with OpenCode, Pi, Droid, Aider, Crush, Cline. Proxy that bridges Anthropic's official SDK to enable Claude Max in third-party tools.
