Yes - it is Apache-2.0 licensed, so it is free for commercial use with attribution.
The framework itself is free - but you will need a model to drive it, which usually means your own API key or a local model.
Frameworks bundle opinions about loops and tools; this SDK gives you harness structure with freedom on the rest. Choose it when you want control without starting from zero.
The README and the official docs site are the fastest path: run the quickstart example first, then adapt it to your use case.
