LangGraph didn't win the "which agent framework" argument by being the friendliest. It won by being the one that doesn't fall over.
Weaviate kept its promise on the license. It quietly built the plumbing to change that later.
Ollama is still the easiest on-ramp to local AI. It's also had its first real security scare.
The SDK didn't get replaced by the Agents API. It got a sibling.
This isn't Microsoft's first agent framework. It's Microsoft admitting the first two weren't going to converge on their own.
CrewAI didn't get worse. It got a name change, a smaller price sheet, and a genuine security scare it actually fixed properly.
ADK is genuinely serious engineering. "Free" is true of the framework, not of what running it actually costs.
Aider still works. The question is whether "still works" is good enough in 2026.
Each one has a free tier or a free open-source core, per its review.

ADK is genuinely serious engineering. "Free" is true of the framework, not of what running it actually costs.

Aider still works. The question is whether "still works" is good enough in 2026.
The obvious choice if your work already lives in Microsoft 365. For everyone else it is a decent free app inside a confusing pricing maze.
