DSPy is a framework from Stanford NLP for building and optimising LLM pipelines programmatically, compiling declarative modules into effective prompts instead of manual tweaking. You configure a model with your own key directly in code or through provider environment variables, and all calls run from your environment through LiteLLM with no DSPy-hosted proxy. Distributed as a Python library. MIT licensed, 37,229 stars, last commit the day of review.

Why this trust score (84/100)

Trust measures how the tool treats your API key and how much of that has been verified. It contains no popularity signal.

  • Key Safety 22/25 — The key is supplied by an environment variable or local config file you control.
  • Request Routing 17/20 — Requests go straight from you to the AI provider.
  • Transparency 20/20 — Source is public under MIT, so anyone can check how the key is handled.
  • Privacy 14/15 — Local-first: it works without sending your data anywhere. Can be self-hosted, so the data path stays inside infrastructure you control.
  • Maintenance 10/10 — Actively developed — commits within the last three months.
  • Verification Confidence 1/10 — Compiled from public documentation by an AI-assisted pass, not independently confirmed.

How your API key is handled

Your API key is supplied via an environment variable or local config file. Requests are sent directly to the AI provider. Because it can be self-hosted, your key never has to touch a third-party backend.

Setup

Install the tool, set your provider API key as an environment variable (or in its config file), and pick a model.
