A free VS Code extension that lets developers test prompts in their editor — without the overhead of formal evaluation tools and infrastructure.
When I update a prompt, I need to verify that it works across a range of different inputs. Usually, that means tediously running the prompt again and again with different inputs, every time I make a change.
Mind Rig me re-run a prompt against 10 different inputs and see all the results side-by-side in my code editor. Basically saves a fixed batch of test inputs so I can re-run the same data set each time I tweak the prompt.
Also runs multiple models at once and compares speed/cost/quality outputs. Supports hundreds of models via Vercel Gateway. Also shows request/response JSONs + usage stats.
- Free and open-source
- Supports Ruby, PHP, Go, C# and Java in addition to JS/TS/Python.
- Connect your Vercel AI Gateway API key to access 100s of model providers.
- Most importantly, it matches your editor's colour theme 🎨
- We also have a Discord community if you need any help getting set up.
