AI agents are the most crowded category in open source right now, which makes selection the hard part rather than availability. Dozens of projects implement broadly the same decision loop; what actually separates them is the tool interface, the error handling when a model returns nonsense, and whether you can extend them without forking.
Every project below is described by what it does and what you can realistically build on top of it, so you can judge fit before spending a week reading source.
