Wingman - LLM API testing

Postman for LLM APIs. A simple yet powerful tool to test LLM APIs.

What it does

• Send messages to LLM providers
• Edit system prompts or choose among popular ones
• Allows quick testing and error debugging

What it does not

• Store your data: prompts, keys or responses (it's only a frontend)
• Persist history and API keys between sessions
• Serves as a chat assistant

Wingman is free and open source software (FOSS) under MIT license. Made for the community by the community. If you think that it deserves more highlight, share it with your peers and give us a star on GitHub.
