CodeGateway

CodeGateway is an OpenAI-compatible AI gateway that gives developers unified access to Anthropic's Claude, OpenAI's models, and more through a single endpoint. Because it speaks the standard OpenAI API format, any tool you already use — Claude Code, Cursor, Codex CLI, Cline, Continue — works after a one-line change to the base_url. There is no SDK swap and no code rewrite, so you can get started without touching your existing workflow.

Smart routing picks a backend based on latency and cost, and it fails over automatically during peak load, so your requests stay reliable even when traffic spikes. Responses stream in real time over SSE, and Anthropic-compatible as well as Codex Responses endpoints are also supported. Built-in usage analytics show real-time token usage, model distribution, and cost breakdowns, which you can export anytime for auditing.

Billing is pay-as-you-go with no subscription and no monthly minimum: top up from just $5, and every new account receives $2 of free trial credit to explore the service. Payments accept cards as well as Alipay and WeChat Pay. Integration takes about five minutes, and you can switch models without rewriting your code.
