IronClaw pros
- Open source with transparent code and flexible deployment options.

- Setup complexity higher due to security hardening requirements
Mastra cons
- TypeScript-only — not suitable for Python-heavy stacks
- Younger ecosystem compared to LangChain or CrewAI
- Primarily a development framework — not a ready-to-use personal assistant
IronClaw gotchas
