Crucible: what it does well

    PyRIT: what it does well

    • Supports automated and human-led red teaming.
    • Includes single- and multi-turn attack strategies.
    • Offers command-line, shell, and graphical interfaces.
    • Scorers can use LLMs, Azure AI Content Safety, or custom logic.
    • Built-in memory supports SQLite or Azure SQL.

    What to know first

    • Requires a Python environment and configured AI endpoints.
    • Local installation prerequisites list Python 3.10 through 3.14.
    • Frontend contributor setup requires Node.js 22 or higher.
    • Shared or deployed configuration should use Azure Key Vault; plaintext .env files are less secure.
