LangGraph
Graph-structured agent orchestration with real control over state and branching. Powerful once it clicks; the learning curve is steeper than the docs admit, and you will read the source.

How I tested it
I ran LangGraph on Python 3.12, version 0.3, across two weeks of ordinary project work — the refactors, the migrations, the test coverage. Not a benchmark harness; the real, unglamorous middle of building something. Last retested 9 days ago, and the notes below come from that run.
Where it lands
The honest read after that stretch is in the verdict and the rating, both of which I revisit on every retest. When either moves, the changelog says why. Nothing here is a one-time score.
Verdict
Not a daily driver yet, but moving in the right direction. Worth watching, and worth a retest next quarter.
