Local Gateway 'my-free-code' Released, Integrating 9 Coding Agents

The local gateway 'my-free-code' has been released, enabling 9 coding agents such as Claude Code and Codex to share model configurations by converting between Anthropic Messages and OpenAI Responses formats. This tool does not make model usage free; instead, it efficiently routes requests to providers offering free or low-cost tiers.

Key Features and Architecture

• Format Conversion: Supports major endpoints like /v1/messages and /v1/responses, providing an admin interface and authentication endpoints.
• Routing and Failover: Supports specifying top-tier models by grade and sequential attempts via FALLBACK_MODELS. It prevents duplicate generation when switching providers after streaming output has started, and excludes failed providers for 2 seconds.
• Provider Connection: Maintains public model names so that client tools cannot distinguish the actual response provider.

Scope and Limitations

• Providers: 50 providers including NVIDIA NIM, OpenRouter, Groq, and DeepSeek are registered, but currently only 46 OpenAI-compatible paths work due to the lack of dedicated adapters for 4 providers such as Azure OpenAI.
• Target Audience: Designed for individual users who alternate between multiple terminal coding tools. It is designed with the assumption of a local environment (127.0.0.1) and is unsuitable as a team-shared gateway.
• License: Follows the MIT license. Users must separately verify each provider's terms of service (such as prohibitions on bypassing free tiers).
