AutoGen is Microsoft's programming framework for building multi-agent AI applications and coding agents that converse, use tools and execute code. Model clients such as OpenAIChatCompletionClient accept an api_key argument directly, or read it automatically from OPENAI_API_KEY, AZURE_OPENAI_API_KEY or GEMINI_API_KEY environment variables, with no Microsoft-hosted key or account required. The code is MIT licensed (LICENSE-CODE); GitHub reports CC-BY-4.0 at the top level because that license covers the accompanying research and docs.

Why this trust score (88/100)

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. Key handling was located in the published source.
  • 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 8/10 — Commits within the last six months.
  • Verification Confidence 7/10 — Key handling was found in the published source by BYOAIK's scanner.

What was checked

Verification tier: SOURCE_VERIFIED — derived from the evidence below, not set by hand.

  • [REPORTED · RESEARCH] This listing was compiled by an AI-assisted research pass over the tool's public website, README and documentation. No person independently confirmed it.
  • [STRONG · SOURCE_SCAN] The user supplies their own OpenAI key: the project references its API key variable. source
  • [CONFIRMED · SOURCE_SCAN] Most recent commit 2026-04-06 — about 4 month(s) ago. source

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.
