Agent frameworks

Choosing a framework means choosing how work will be orchestrated, not only which library gets installed.

This page compares orchestration styles, runtimes and control models so you can place each option correctly without pretending there is a universal winner.

How to read this comparison

  1. 1

    Model

    Pick the control model first

    Decide whether your team needs role routing, state graphs or typed outputs before comparing frameworks.

  2. 2

    Runtime

    Map the toolchain to the stack

    Language matters only when it matches hosting, typing and integration constraints.

  3. 3

    Reality check

    Treat this as an editorial board, not a benchmark

    The page shows architecture patterns and workflow fit. It does not claim a live reliability ranking.
