Comparison Preset
AutoGen is the more prudent choice for an enterprise setting, primarily due to risk and stability. It carries a defined CC-BY-4.0 license, has zero known vulnerabilities, and a high bus factor of 9/10, which are all critical for long-term maintainability and security reviews. Its 58k GitHub stars and over 850k monthly downloads demonstrate broad adoption and a substantial support community. Mastra's 'NOASSERTION' license status presents an unacceptable legal ambiguity for enterprise use. AutoGen's maturity, proven over 1005 days, provides a more stable and defensible foundation for business-critical systems.
Overview
