Features

Everything you need for perfect prompts

DSPyLab combines the power of the DSPy framework with an intuitive interface so you can optimize your prompts like an expert.

Real DSPy

Uses Stanford's DSPy framework, not simulations. ChainOfThought, Predict, and more real modules.

Multiple Variants

Generate up to 5 variants with different temperatures. The system evaluates and selects the best one automatically.

LLM-as-Judge

Automatic evaluation of clarity, specificity and effectiveness. Scores from 1-10 for each variant.

80+ Models

GPT-4o, Gemini 3, O1/O3, and more. OpenAI + Google Gemini with transparent pricing.

Detailed Analytics

Track tokens, costs and usage by model. Complete billing and statistics dashboard.

Reusable Blocks

Save contexts, prompts and outputs as blocks. Build prompts like LEGO.
