PromptShuttle
De-couple your prompts from your code
PromptShuttle is a prompt template manager, allowing non-technical users to collaborate on prompts and manage active versions for different environments which are exposed through the API.
It logs requests and responses, and replaces [[tokens]] with values provided through the API. You can also proxy requests to OpenAI, Anthropic, Gemini and Groq and thus simplify billing.
