CORS Chat tool enables browser-based chat with OpenAI-Responses-compatible APIs via CORS
↗
CORS Chat is a web UI that lets developers test OpenAI-Responses-compatible endpoints with CORS support directly in the browser.
Engineers can exercise LLM endpoints without building a server-side proxy, reducing setup time for local testing. The tool’s ability to persist chats, export JSON, and render SVG images while tokens stream gives immediate debugging insight, especially for models like Qwen 3.8 27B running in LM Studio.
