Lightweight, yet comprehensive prompt playground architecture that lets FileMaker developers create, version, and compare prompts and their outputs across multiple LLMs through free or paid models via any provider e.g. OpenRouter or locally via LM Studio . Endpoints, Models, Sources can all be dynamic making it a trully exciting way to track your prompt libaries and see them in action and compare results over time with a prompting and execution log.
This uses only native FileMaker 2025 script steps. No plugins or addons . FileMaker 2025 makes all of this possible without the Insert From URL step too.
This repository includes the full XML copy and DDR, so you can explore the schema in detail using DDR tools like FM Perception or InspectorPro.
- Create a New Prompt / Edit Existing Prompts.
- Edit and Automatically save Version History.
- Run a Prompt from Playground with dynamic variables for models, endpoint, temperature settings etc.
- Keep track of executions, models, prompts and version.
- 🔀 Route prompts to multiple models and compare outputs side by side
- 📝 Create and version JSON based prompts directly inside FileMaker and also pass in data from the database
- 🧪 Run controlled experiments
- 💾 Log every execution
or there is also a custom GPT from the same authaor for creating powerful, structured JSON Prompts . This GPT is based on the smart metamprompting technique outlined at https://github.com/binu-alexander/metaprompter by the same author. https://chatgpt.com/g/g-68aea2a957a8819186af31f366b178df-baxter-prompt-butler-json.
